Small Business Research Programs:
August 17, 2021
SBIR and STTR
Marcy E. Gallo
The Small Business Innovation Research (SBIR) program was established in 1982 by
Analyst in Science and
the Small Business Innovation Development Act (P.L. 97-219) to increase the
Technology Policy
participation of small innovative companies in federally funded research and

development (R&D). The act requires federal agencies with extramural R&D budgets of
$100 million or more to set aside a portion of these funds to finance an agency-run SBIR

program. As of 2021, 11 federal agencies operate SBIR programs. A complementary program, the Small Business
Technology Transfer (STTR) program, was created by the Small Business Research and Development
Enhancement Act of 1992 (P.L. 102-564) to facilitate the commercialization of university and federal R&D by
small companies. Agencies with extramural R&D budgets of $1 billion or more are required to set aside a portion
of these funds to finance an agency-run STTR program. As of 2021, five federal agencies operate STTR
programs.
Both the SBIR and STTR programs have three phases. Phase I funds feasibility-related R&D related to agency
requirements. Phase II supports further R&D efforts initiated in Phase I that meet particular program needs and
exhibit potential for commercial application. Phase III is focused on commercialization of the results of Phase I
and Phase II grants; the SBIR and STTR programs do not provide funding in Phase III.
The SBIR and STTR programs have been extended and reauthorized several times since their initial enactments.
In 2016, the programs were extended through September 30, 2022, by the National Defense Authorization Act for
Fiscal Year 2017 (P.L. 114-328). In 2018, Congress extended the authority of existing pilot programs and created
new pilot programs associated with the SBIR and STTR programs, among other activities, as part of the John S.
McCain National Defense Authorization Act for Fiscal Year 2019 (P.L. 115-232). Among its provisions, the act
extended (through FY2022) the pilot programs authorizing the use of SBIR and STTR funds for (1)
administrative costs, outreach, and contract processing activities, and (2) technology development, testing,
evaluation, and commercialization assistance; required the Department of Defense (DOD) to create a pilot
program to accelerate the process for awarding SBIR and STTR awards; and required federal agencies with SBIR
and STTR programs to establish a Commercialization Assistance Pilot Program.
Through FY2018, the most recent year with published annual report data, federal agencies had made 171,680
awards totaling $51.0 billion under the SBIR and STTR programs. In FY2018, agencies awarded $2.8 billion in
SBIR funding. DOD and the Department of Health and Human Services (HHS) accounted for more than three-
fourths of SBIR funding in FY2018. While the majority of SBIR grants made in FY2018 were Phase I awards
(65%), more than three-fourths (78%) of SBIR funding went to Phase II awards. In FY2018, agencies awarded
$382.4 million in STTR funding. DOD and HHS accounted for more than three-fourths of STTR funding (80%).
Like the SBIR program, most STTR grants (72%) were for Phase I awards, while most funding (68%) went to
Phase II awards.
In exercising its oversight of the SBIR and STTR programs, Congress has expressed continuing interest in the
amount of agency funding set aside for the programs, the effectiveness of efforts seeking to improve
commercialization outcomes, the share of awards and funding received by women-owned and minority and
disadvantaged firms, the geographic distribution of awards and funding, and the Small Business Administration’s
responsibilities under the programs, including agency coordination, policy guidance, and data collection.

Overview1
Congress established the Small Business Innovation Research (SBIR) program in 1982 to expand
the role of small businesses in federal research and development (R&D). When establishing the
program, Congress declared that technological innovation plays an important role in job creation,
productivity improvements, and U.S. competitiveness; that small businesses are among the most
cost-effective performers of R&D and particularly capable of bringing R&D results to market in
the form of new products; and that, despite the role of small businesses as “the principal source of
significant innovations in the Nation,” the vast majority of federally funded R&D is performed by
large businesses, universities, and federal laboratories.2 With this in mind, Congress established
the SBIR program to advance four objectives:
 to stimulate innovation,
 to use small businesses to meet federal R&D needs,
 to foster and encourage the participation of minority and disadvantaged persons in
technological innovation, and
 to increase private sector commercialization of innovations derived from federally
funded R&D.3
In 1992, Congress established the Small Business Technology Transfer (STTR) program.4 Similar
in design to the SBIR program, STTR was created to facilitate the commercialization of
university and federal R&D by small companies.
Execution of the SBIR and STTR programs is decentralized. Both the SBIR and STTR statutes
require that federal agencies with extramural R&D budgets in excess of specified amounts set
aside a percentage of such funds to conduct their own SBIR and STTR programs.5 Currently, 11
federal departments and agencies operate SBIR programs and 5 operate STTR programs. The
Small Business Administration (SBA) helps to coordinate the SBIR and STTR programs,
establishes overall policy guidance, reviews agencies’ progress, and reports annually to Congress
on the operation of the programs.
Through FY2018, the most recent year with complete data, federal agencies had made 171,680
SBIR and STTR awards to small businesses to develop and commercialize innovative
technologies. The total amount awarded was $51.0 billion. Figure 1 shows SBIR and STTR
funding for FY2000-FY2018.

5 The percentages identified in law which must be set aside for SBIR and STTR are minimums; agencies may set aside
more than these percentages. Federal R&D funding can be characterized as either extramural or intramural depending
on the individuals and organizations performing the R&D. Extramural R&D is performed by organizations outside the
federal sector that perform R&D with federal funds under contract, grant, or cooperative agreement, including
universities and colleges, industrial firms, federally funded research and development centers, state and local
governments, and foreign performers. Intramural R&D is performed by employees of a federal agency in or through
government-owned, government-operated facilities.

Data Sources and Limitations
This report uses the data reported to SBA and included in the required annual reports to Congress
for the information and analysis presented below. The latest annual report data available to CRS
is for FY2018. While the SBA, through its SBIR.gov website, does makes available certain data
on SBIR and STTR awards from the inception of the SBIR and STTR programs through the
current fiscal year, the award database is considered “live data” and open for continuous revision
throughout the year.6 Additionally, as of the date of this report, the award database for FY2021 is
incomplete (i.e., eight agencies have not posted data for FY2021). While the award database for
FY2019 and FY2020 is complete (i.e., each of the agencies with SBIR and STTR programs has
posted its data), SBA does not independently review such data for quality or accuracy until the
data is used as part of the required annual report. According to SBA, “the review process does
identify places where data is inaccurate,” and “after the agencies and SBA work to ensure the data
is accurate it goes through a formal OMB [Office of Management and Budget] review.”7 As of the
date of this report, SBA has not completed the FY2019 annual report, however, SBA has
indicated that “once the annual report is complete the number of changes to the award database

related discussion.)
Small Business Innovation Research
SBIR Overview
The Small Business Innovation Research (SBIR) program was established under the Small
Business Innovation Development Act of 1982 (P.L. 97-219) and has subsequently been
reauthorized or extended multiple times, most recently in 2016 when the program was extended
through September 30, 2022.9 Under the program, each federal agency with an extramural R&D
budget greater than $100 million is required to allocate a portion of that funding to conduct a
multi-phase R&D grant program for small businesses. The objectives of the SBIR program
include stimulating technological innovation, increasing the use of the small business community
to meet federal R&D needs, fostering and encouraging participation in innovation and
entrepreneurship by minorities and socially and economically disadvantaged individuals, and
expanding private sector commercialization of innovations resulting from federally funded R&D.
Currently, 11 federal agencies participate in the SBIR program: the Departments of Agriculture
(USDA), Commerce (DOC), Defense (DOD), Education (ED), Energy (DOE), Health and
Human Services (HHS), Homeland Security (DHS), and Transportation (DOT); the
Environmental Protection Agency (EPA); the National Aeronautics and Space Administration
(NASA); and the National Science Foundation (NSF).
Each participating agency operates its own SBIR program under the provisions of the law and
regulations, as well as with guidance issued by the U.S. Small Business Administration in its
Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR)
Program Policy Directive
(referred to hereinafter as the Policy Directive).10 According to some
analysts, this approach allows for general consistency across SBIR programs, while allowing each
agency a substantial degree of control and flexibility in the execution of its program in alignment
with its overall mission and priorities.11 (See “Improving Technology Commercialization and
Trade-Offs Among Program Objectives”
herein for related discussion.)
In FY2017 and later years, federal agencies participating in the SBIR program are required to set
aside at least 3.2% of their extramural R&D funds for the SBIR program. In FY2018, the
aggregate level of SBIR funding for all federal agencies was $2.776 billion ($1.610 billion for the
10 participating civilian agencies and $1.166 billion for DOD). The aggregate level of SBIR
funding for the civilian agencies ($1.610 billion) accounted for approximately 3.25% of the
participating agencies’ aggregate extramural R&D funding, as reported to SBA. Overall, the
civilian agencies participating in the SBIR program obligated the required 3.2%; however,
individually, 6 of the 10 civilian agencies failed to comply with the minimum spending
requirement. Specifically, HHS, NASA, USDA, ED, DOT, and EPA did not meet the SBIR
spending requirement in FY2018. The percentage of SBIR funding set aside from DOD’s

extramural R&D funds in FY2018 accounted for 2.38% of DOD’s extramural R&D funding, as
reported to SBA, well below the required 3.2%.12 Overall, DOD did not meet the minimum
spending requirement for the SBIR program; however, 4 of the 12 DOD components SBA
collects data from did comply with the spending requirement—Defense Advanced Research
Projects Agency (DARPA), U.S. Special Operations Command (SOCOM), Defense Threat
Reduction Agency (DTRA), and Defense Logistics Agency (DLA) (See “Agency Compliance
with Mandatory Minimum Expenditures”
herein for related discussion.)
SBIR Phases
The SBIR program is a three-phase program. The purposes and parameters of each phase are
discussed below.
Phase I
In Phase I, an agency solicits contract proposals or grant applications to conduct feasibility-
related experimental or theoretical research or research and development (R/R&D) related to
agency requirements. The scope of the topic(s) in the solicitation may be broad or narrow,
depending on the needs of the agency. Phase I grants are intended to determine “the scientific and
technical merit and feasibility of ideas that appear to have commercial potential.”13 Generally,
SBIR Phase I awards are not to exceed $150,000, adjusted for inflation, though the law provides
agencies with the authority to issue awards that exceed this amount (the Phase I award guideline)
by as much as 50%.14 In addition, agencies may request a waiver from the SBA to exceed the
award guideline by more than 50% for a specific topic.15 In general, the period of performance for
Phase I awards is up to six months, though agencies may allow for a longer performance period
for a particular project.
Phase II
Phase II grants are intended to further R/R&D efforts initiated in Phase I that meet particular
program needs and that exhibit potential for commercial application. In general, only Phase I
grant recipients are eligible for Phase II grants. There are two exceptions to this guideline: (1) a
federal agency may issue an SBIR Phase II award to a Small Business Technology Transfer
(STTR) Phase I awardee to further develop the work performed under the STTR Phase I award;16
and (2) through FY2022, the National Institutes of Health (NIH), DOD, and ED are authorized to
make Phase II grants to small businesses that did not receive Phase I awards. Exercise of either of
these exceptions requires a determination from the agency head that the small business has
demonstrated the scientific and technical merit and feasibility of the ideas and that the ideas
appear to have commercial potential.17

Small Business Research Programs: SBIR and STTR

Phase II awards are to be based on the results achieved in Phase I (when applicable) and the
scientific and technical merit and commercial potential of the project proposed in Phase II as
evidenced by: the small business concern’s record of successfully commercializing SBIR or other
research; the existence of second phase funding commitments from private sector or non-SBIR
funding sources; the existence of third phase, follow-on commitments for the subject of the
research; and the presence of other indicators of the commercial potential of the idea.18
The Policy Directive generally limits SBIR Phase II awards to $1 million, adjusted for inflation,
(the Phase II award guideline), though the directive provides agencies with the authority to issue
an award that exceeds this amount by as much as 50%. As with Phase I grants, agencies may
request a waiver from the SBA to exceed the Phase II award guideline by more than 50% for a
specific topic.19 In general, the period of performance for Phase II awards is not to exceed two
years, though agencies may allow for a longer performance period for a particular project.
Agencies may make a sequential Phase II award to continue the work of an initial Phase II award.
The amount of a sequential Phase II award is subject to the same Phase II award guideline and
agencies’ authority to exceed the guideline by up to 50%. Thus, agencies may award up to $3
million, adjusted for inflation, in Phase II awards for a particular project to a single recipient at
the agency’s discretion, and potentially more if the agency requests and receives a waiver from
the SBA. For sequential Phase II awards, some agencies require third party matching of the
agency’s SBIR funds.
Phase III
Phase III of the SBIR program is focused on the commercialization of results achieved with
Phase I and Phase II SBIR funding. The SBIR program does not provide funding in Phase III.
Phase III funding is expected, generally, to be generated in the private sector. However, some
agencies may use non-SBIR funds for Phase III funding to support additional R&D or contracts
for products, processes, or services intended for use by the federal government. In addition, the
law directs agencies and prime contractors “to the greatest extent practicable,” to facilitate the
commercialization of SBIR and STTR projects through the use of Phase III awards, including
sole source awards.20
Technical Assistance
In addition to funding provided in Phases I-III, the law also allows agencies to award SBIR Phase
I recipients up to $6,500 per year, and Phase II award recipients up to $50,000 per project, for
technical and business assistance, in addition to the amount of the base award, or to provide such
assistance through an agency-selected vendor.21 This funding is intended to provide SBIR
recipients with services such as access to a network of scientists and engineers engaged in a wide
range of technologies; assistance with product sales, intellectual property protections, market
research, market validation, and development of regulatory plans and manufacturing plans; or
access to technical and business literature available through online databases. These services are
provided to help SBIR awardees make better technical decisions, solve technical problems,

18 15 U.S.C. §638(e)(4)(b).
19 According to SBA, as of November 2019, agencies may issue a Phase II award up to $1,710,531 without seeking a
waiver from SBA.

minimize technical risks, and develop and commercialize new commercial products and
processes.22
SBIR Eligibility
A small business’s eligibility for the SBIR program is contingent on its location, number of
employees, ownership characteristics, and other factors. Eligibility to participate in the SBIR
program is limited to for-profit U.S. businesses with a location in the United States. Eligible
companies must have 500 or fewer employees, including employees of affiliates. The small
business must be
(1) more than 50% directly owned and controlled by one or more citizens or permanent
resident aliens of the United States, other small business concerns (each of which is more
than 50% directly owned and controlled by individuals who are citizens or permanent
resident aliens of the United States), an Indian tribe, Alaskan Native Corporation (ANC) or
Native Hawaiian organization (NHO) (or a wholly owned business entity of such tribe, ANC
or NHO), or any combination of these; or
(2) more than 50% owned by multiple venture capital operating companies, hedge funds,
private equity firms,23 or any combination of these, with no single such firm owning more
than 50% of the small business;24 or
(3) a joint venture in which each entity to the joint venture meets the requirements in
paragraphs (1) and (2) above.25
Agencies are restricted on how much of their SBIR funds they can make available for awards to
small businesses that are more than 50% owned by venture capital operating companies, hedge
funds, or private equity firms. The NIH, DOE, and NSF may award no more than 25% of their
SBIR funds to such small businesses; all other SBIR agency programs are limited to using 15%
of their SBIR funds for such awards.26
Small businesses that have received multiple prior SBIR/STTR awards must meet certain bench-
mark requirements for progress toward commercialization to be eligible for a new Phase I award
(see “Improving Technology Commercialization and Trade-Offs Among Program Objectives”
herein for related discussion). For both Phase I and Phase II, the principal investigator’s primary
employment must be with the small business applicant at the time of award and during the
conduct of the proposed project.27

24 According to SBA, “The exception to this is if the VC is itself more than 50% directly owned and controlled by one
or more individuals who are citizens or permanent resident aliens of the United States. In such a case, that VC is
allowed to have majority ownership and control of the awardee. In that case, the VC and the awardee, and all other
affiliates, must have a total of 500 employees or less.” Source: SBA, “Frequently Asked Questions: VC Participation,”

Generally, R/R&D work under an SBIR award must be performed in the United States, though
agencies may allow a portion of the work to be performed or obtained outside of the United
States under “rare and unique” circumstances.28
Recent and Historical SBIR Awards Data29
In FY2018, the most recent year for which the SBA has published annual report data on SBIR
awards, agencies made awards for $2.776 billion, including 3,135 Phase I awards totaling $600.8
million and 1,703 Phase II awards totaling $2.142 billion. The success rate30 was 16% for Phase I
SBIR proposers and 55% for Phase II proposers.
While more than half of SBIR awards made in FY2018 were Phase I awards (65%), more than
three-fourths of SBIR funding went to Phase II awards (78%).31 Between FY2000 and FY2018,
funding for Phase I remained relatively stable while Phase II funding generally increased. See
Figure 2.

($1.166 billion, 42%) and HHS ($930.9 million, 34%). The next three highest SBIR funding
agencies (DOE, NSF, and NASA) together accounted for almost 22%. The remaining agencies
accounted for nearly 3%. See Figure 3.

The allocation of SBIR funding between Phase I and Phase II awards varies among agencies.
Agencies that allocated the largest share of their SBIR funding to Phase I awards in FY2018 were
EPA (48%), DOT (42%), and ED (36%). Agencies that allocated the largest share of their SBIR
funding to Phase II awards in FY2018 were DOD (85%), DHS (78%), and NASA (78%). Figure

, Tables 2, 3, and 8.
In FY2018, women-owned small businesses received 407 Phase I awards (13% of all Phase I
SBIR awards) totaling $79.3 million (13% of total Phase I funding), and 212 Phase II SBIR
awards (12%) totaling $253.5 million (12%).32 Socially and economically disadvantaged
businesses received 209 Phase I awards (7% of all Phase I SBIR awards) totaling $38.9 million
(6% of total Phase I funding), and 97 Phase II SBIR awards (6%) totaling $98.1 million (5%).33
Companies in Historically Underutilized Business Zones (HUBZones) received 106 Phase I
awards (3% of all Phase I awards) totaling $17.7 million (3% of total Phase I funding) and 38
Phase II awards (2%) totaling $37.0 million (2%).34
Figure 6 shows the aggregate funding level and number of SBIR awards by state for FY2014-
FY2018 (the latest five-year period for which annual report award data by state are available).
Although every state, the District of Columbia, and Puerto Rico received awards during this
period, SBIR funding was concentrated among certain states. The two states that received the
largest number and amount of SBIR awards during this period—California (5,041 awards totaling
$2.539 billion) and Massachusetts (2,590 awards totaling $1.386 billion)—accounted for 33% of
the total number of SBIR awards and 33% of the total funding for this period.
The top ten states—California, Massachusetts, Virginia, Maryland, Colorado, New York,
Pennsylvania, Texas, Ohio, and North Carolina—accounted for more than two-thirds of SBIR
awards and funding. This concentration is similar to overall federal R&D funding for FY2018.
Eight of the top ten states in SBIR funding are also among the top ten states in overall federal
R&D funding in FY2018 (which accounted for 54% of total federal R&D funding).35 In contrast,
the ten states with the fewest number of SBIR awards and lowest aggregate award amounts—
North Dakota, Alaska, Puerto Rico, Mississippi, South Dakota, Idaho, West Virginia, Wyoming,
Nebraska, and Maine—accounted for about 1% of awards and total funding during this period.

32 According to SBA, women-owned small businesses are small businesses that are “at least 51% owned by one or
more women, or in the case of any publicly owned business, at least 51% of the stock is owned by women, and women
control the management and daily business operations;” SBA, Small Business Innovation Research Program Policy
Directive
, May 2, 2019, p. 67.
33 According to SBA, socially and economically disadvantaged businesses must meet the eligibility requirements set
forth in 13 C.F.R. part 124, subpart B; SBA, Small Business Innovation Research (SBIR) and Small Business
Technology Transfer (STTR) Program Policy Directive
, May 2, 2019, p. 66.

Small Business Technology Transfer
STTR Overview
The Small Business Technology Transfer program was created by the Small Business Research
and Development Enhancement Act of 1992 (P.L. 102-564) and has been reauthorized several
times, most recently in 2016 when the program was extended through September 30, 2022.37
Modeled largely after the SBIR program, the STTR program seeks to facilitate the
commercialization of university and federal R&D by small companies. Under the program, each
federal agency with an extramural R&D budget of $1 billion or more is required to allocate a
portion of its R&D funding to conduct a multi-phase R&D grant program for small businesses.
The STTR program provides funding for research proposals that are developed and executed
cooperatively between a small firm and a scientist in an eligible research institution38 and that are
aligned with the mission requirements of the federal funding agency.

37 Section 1834 of the National Defense Authorization Act for Fiscal Year 2017 (P.L. 114-328).
38 According to the SBA, an eligible “research institution” is defined, for purposes of the STTR, as
One that has a place of business located in the United States, which operates primarily within the
United States or which makes a significant contribution to the U.S. economy through payment of
taxes or use of American products, materials or labor, and is: (1) A non-profit institution as defined
in section 4(3) of the Stevenson-Wydler Technology Innovation Act of 1980 (that is, an
organization that is owned and operated exclusively for scientific or educational purposes, no part
of the net earnings of which inures to the benefit of any private shareholder or individual); or (2) A

Currently, five agencies participate in the STTR program: DOD, DOE, HHS, NASA, and NSF. In
FY2016 and later years, federal agencies participating in the STTR program are required to set
aside at least 0.45% in funding for the program. In FY2018, total STTR award funding among all
STTR-participating federal agencies was $382.4 million ($207.0 million for the four participating
civilian agencies and $175.4 million for DOD). The aggregate level of STTR funding for the
civilian agencies accounted for 0.44% of the participating agencies’ aggregate extramural R&D
funding, as reported to SBA. Specifically, HHS and NASA complied with the minimum spending
requirement of 0.45%, while the DOE and NSF failed to comply. The percentage of STTR
funding set aside from DOD’s extramural R&D funds was 0.36%, as reported to SBA, also below
minimum spending requirement. However, 3 of the 12 DOD components SBA collects data from
did comply with the spending requirement—SOCOM, DTRA, and DLA.
The SBA emphasizes three principal differences between the STTR and SBIR programs:
 Under STTR, the small business and its partnering research institution must
establish an intellectual property agreement detailing the allocation of intellectual
property rights and rights to carry out follow-on research, development, or
commercialization activities.
 Under STTR, the small business partner must perform at least 40% of the R&D,
and the research institution partner must perform at least 30% of the R&D.
 The STTR program does not require the principal investigator to be primarily
employed by the small business, a requirement of the SBIR program.39
As with the SBIR program, each participating agency operates its own STTR program under the
provisions of the law and regulations, as well as with guidance issued by the SBA in its Policy
Directive
. According to some analysts, this approach allows for general consistency across STTR
programs, while allowing each agency a substantial degree of control and flexibility in the
execution of its program in alignment with its overall mission and priorities.40 (See “Improving
Technology Commercialization and Trade-Offs Among Program Objectives”
herein for related
discussion.)
STTR Phases
Like the SBIR program, the STTR program has three phases. The purposes and parameters of
each phase are discussed below.

in accordance with the Federal Acquisition Regulation issued in accordance with section 35(c)(1)
of the Office of Federal Procurement Policy Act (or any successor regulation). A non-profit
institution can include hospitals and military educational institutions, if they meet the definition
above.

Phase I
In Phase I, an agency solicits contract proposals or grant applications to conduct feasibility-
related experimental or theoretical research or research and development (R/R&D) related to
agency requirements. The scope of the topic(s) in the solicitation may be broad or narrow,
depending on the needs of the agency. Phase I grants are intended to determine “the scientific and
technical merit and feasibility of the proposed effort and the quality of performance of the [small
business] with a relatively small agency investment before consideration of further Federal
support in Phase II.”41 Generally, STTR Phase I awards are limited to the same award guideline
amount as SBIR Phase I awards (see “SBIR Phases” above). Similar to SBIR Phase I awards,
agencies may issue STTR Phase I awards that exceed the guideline amount by as much as 50%
and may request a waiver from the SBA to exceed the award guideline by more than 50% for a
specific topic.42 In general, the period of performance for Phase I awards is not to exceed one
year, though agencies may allow for a longer performance period for a particular project.
Phase II
Phase II grants are intended to further R/R&D efforts initiated in Phase I that meet particular
program needs and that exhibit potential for commercial application. In general, only Phase I
grant recipients are eligible for Phase II grants.43 Awards are to be based on the results achieved in
Phase I and the scientific and technical merit and commercial potential of the project proposed in
Phase II. The Policy Directive generally limits STTR Phase II awards to $1 million, adjusted for
inflation (the Phase II award guideline). As with Phase I grants, agencies may issue awards that
exceed this guideline by as much as 50% and may request a waiver from the SBA to exceed the
guideline by more than 50% for a specific topic.44 In general, the period of performance for Phase
II awards is not to exceed two years, though agencies may allow for a longer performance period
for a particular project. Agencies may make a sequential Phase II award to continue the work of
an initial Phase II award. This sequential Phase II award is also subject to the Phase II award
guideline amount and agencies’ authority to exceed the guideline by up to 50%. Thus, agencies
may award up to $3 million, adjusted for inflation, in Phase II awards for a particular project to a
single recipient at the agency’s discretion, and potentially more if the agency requests and
receives a waiver from the SBA. For sequential Phase II awards, some agencies require third-
party matching of the agency’s STTR funds.
Phase III
Phase III of the STTR program is focused on the commercialization of the results achieved
through Phase I and Phase II STTR funding. The STTR program does not provide funding in

, May 2, 2019, p. 68.
42 According to SBA, as of November 2019, agencies may issue a Phase I award up to $256,580 without seeking a
waiver from SBA.
43 “A federal agency may, however, issue an STTR Phase II award to an SBIR Phase I awardee to further develop the
work performed under the SBIR Phase I award…. An agency must base its decision upon the results of work performed
under the Phase I award and the scientific and technical merit and commercial potential of the Phase II proposal. The
Phase I Awardee must meet the eligibility and program requirements of the Phase II program from which it will receive
the award in order to receive the Phase II award.” Source: SBA, Small Business Innovation Research (SBIR) and Small
Business Technology Transfer (STTR) Program Policy Directive,
May 2, 2019, p. 69.

Phase III. Phase III funding is expected, generally, to be generated in the private sector. However,
some agencies may use non-STTR funds for Phase III funding to support additional R&D or
contracts for products, processes, or services intended for use by the federal government. In
addition, the law directs agencies and prime contractors “to the greatest extent practicable,” to
facilitate the commercialization of SBIR and STTR projects through the use of Phase III awards,
including sole source awards.45
Technical Assistance
The law also allows agencies to award STTR Phase I recipients up to $6,500 per year, and Phase
II award recipients up to $50,000 per project, for technical and business assistance, in addition to
the amount of the base award, or to provide such assistance through an agency-selected vendor.
This funding is intended to provide STTR recipients with services such as access to a network of
scientists and engineers engaged in a wide range of technologies; assistance with product sales,
intellectual property protections, market research, market validation, and development of
regulatory plans and manufacturing plans; or access to technical and business literature available
through online databases. These services are provided to help STTR awardees make better
technical decisions, solve technical problems, minimize technical risks, and develop and
commercialize new commercial products and processes.46
STTR Eligibility
A small business’ eligibility for the STTR program is contingent on its location, number of
employees, ownership characteristics, and other factors. The partnering research institution must
meet eligibility qualifications as well. Eligibility to participate in the STTR program is limited to
for-profit U.S. businesses with a location in the United States. Eligible companies must have 500
or fewer employees, including employees of affiliates.
The small business must be
(1) more than 50% directly owned and controlled by one or more citizens or permanent
resident aliens of the United States, other small business concerns (each of which is more
than 50% directly owned and controlled by individuals who are citizens or permanent
resident aliens of the United States), an Indian tribe, Alaskan Native Corporation (ANC), or
Native Hawaiian Organization (NHO), a wholly owned business entity of such tribe, ANC, or
NHO, or any combination of these; or
(2) a joint venture in which each entity to the joint venture meets the requirements in
paragraph (1) above.47
Unlike the SBIR program, the STTR program does not have authority to make awards to small
businesses that are more than 50% owned by multiple venture capital (VC) operating companies,
hedge funds, private equity firms, or any combination of these. However, as with SBIR, the
STTR program may make awards to companies that are majority-venture capital backed if the VC
firm is itself more than 50% directly owned and controlled by one or more individuals who are
citizens or permanent resident aliens of the United States. In such a case, that VC is allowed to

have majority ownership and control of the awardee; however, the VC and the awardee, and all
other affiliates, must have a total of 500 employees or less.48
In addition, small businesses that have received multiple prior SBIR/STTR awards must meet
certain benchmark requirements for progress toward commercialization to be eligible for a new
Phase I award. For both Phase I and Phase II, the principal investigator’s primary employment
must be with either the small business or the partnering research institution at the time of award
and during the conduct of the proposed project. Generally, R/R&D work under the STTR must be
performed in the United States, though agencies may allow a portion of the work to be performed
or obtained outside of the United States under “rare and unique” circumstances.49
The partnering research institution must be located in the United States, and be either a nonprofit
college or university, a domestic nonprofit research organization,50 or a federally funded research
and development center (FFRDC).51
For both Phase I and Phase II, not less than 40% of the R/R&D work must be performed by the
small business, and not less than 30% of the R/R&D work must be performed by the single,
partnering research institution. Agencies may choose whether to determine these percentages
using either contract dollars or labor hours, but must explain this in the solicitation.52
Recent and Historical STTR Awards Data53
In FY2018, the most recent year for which the SBA has published annual report data on STTR
awards, agencies made awards for $381.7 million, including 568 Phase I STTR awards totaling
$121.6 million and 224 Phase II STTR awards totaling $260.1 million. The success rate was 19%
for Phase I STTR proposers and 47% for Phase II proposers. While 72% of STTR grants made in
FY2018 were for Phase I awards, more than 68% of STTR funding went to Phase II awards.
Figure 7 shows Phase I and Phase II STTR funding for FY2000-2018. In FY2004, the minimum
percentage that participating agencies were required to set aside for the STTR program doubled
from 0.15% to 0.30%. The STTR set-aside remained at 0.30% through FY2011. In the first year
the set-aside doubled (FY2004), total funding for STTR approximately doubled. However, from
FY2004 to FY2011, Phase I aggregate funding fell by about 25% while Phase II aggregate
funding increased by about 74%. From FY2012 to FY2016 the STTR set-aside increased in steps

Directive
, May 2, 2019, p. 85.
50 As defined in 15 U.S.C. §3703(3) a nonprofit institution is “an organization owned and operated exclusively for
scientific or educational purposes, no part of the net earnings of which inures to the benefit of any private shareholder
or individual.”
51 Chapter 35 of the Federal Acquisition Regulation provides the following explanation and purposes of FFRDCs:
An FFRDC meets some special long-term research or development need which cannot be met as
effectively by existing in-house or contractor resources. FFRDC’s enable agencies to use private
sector resources to accomplish tasks that are integral to the mission and operation of the sponsoring
agency.... FFRDC’s are operated, managed, and/or administered by either a university or
consortium of universities, other not-for-profit or nonprofit organization, or an industrial firm, as an

Small Business Research Programs: SBIR and STTR

Issues for Consideration
Since establishing the SBIR and STTR programs, Congress has sought to better understand and
address challenges to the programs’ effectiveness. The following section provides an overview of
selected ongoing issues that Congress may consider.
Eligibility of Venture Capital-Backed Small Businesses
Much of the debate over the reauthorization of the SBIR and STTR programs in 2011 revolved
around a regulation that required at least 51% ownership by an individual or individuals to be
eligible for participation in the programs.54 Some experts argued that participation by small firms
that are majority-owned by venture capital companies, hedge funds, and private equity firms
should be permitted. Proponents of this change maintained that, particularly in the biotechnology
sector, the most innovative companies were not able to use the SBIR program because they did
not meet these ownership criteria. Opponents of altering the eligibility requirements argued that
the program is designed to provide financial assistance where venture capital is not available.
They asserted that the program’s objective is to bring new concepts to the point where private
sector investment is feasible.
The SBIR/STTR Reauthorization Act of 2011 (enacted as Division E of the National Defense
Authorization Act for Fiscal Year 2012, P.L. 112-81) authorized NIH, DOE, and NSF to award up
to 25% of their SBIR funds to small firms that are majority-owned by venture capital (VC)
companies, hedge funds, or private equity firms. The law also authorized all other SBIR
participating agencies to award up to 15% of their SBIR funds to such small firms. Prior to the
use of this authority, an agency must submit a written determination to SBA and Congress that
explains how including such firms in the SBIR program will
 induce additional venture capital, hedge fund, or private equity firm funding of
small business innovations;
 substantially contribute to the mission of the federal agency;
 demonstrate a need for public research; and
 otherwise fulfill the capital needs of small business concerns for additional
financing for SBIR projects.55
P.L. 112-81 also required the U.S. Government Accountability Office (GAO) to conduct a study
every three years on the impact of allowing small firms majority-owned by venture capital
companies, hedge funds, and private equity firms to participate in the SBIR program.56 In 2021,
GAO released its most recent report examining federal agencies’ use of the authority.57 GAO
found that four agencies—NIH, ED, DOE’s Advanced Research Projects Agency-Energy (ARPA-
E), and DOD—submitted written determinations to SBA for the use of the authority between
FY2015 and FY2020; only NIH, ED, and DOD actually made awards using the authority during

54 In 2003, an SBA administrative judge ruled that the term “individuals” means only natural persons and does not
include venture capital funds, pension funds, and corporate entities for purposes of an SBIR award, see National
Research Council, Venture Funding and the NIH SBIR Program, Washington, DC, 2009, Appendix F, “SBA
Administrative Ruling on Appeal of Cognetix, Inc,,” p. 95.

the FY2019 and FY2020 period under review.58 According to GAO, NIH—the only agency to use
the authority with any regularity—made 43 awards totaling over $30.5 million, ED made one
award for $899,072, and DOD made one award for $149,900. GAO indicated that agencies use
the authority provided by P.L. 112-81 for a variety of reasons, including “they believe that it helps
deploy the strongest innovations, fills potential gaps in private sector investment, or are interested
in ideas regardless of the source.”59 In contrast, as previously reported by GAO, federal agencies
with SBIR programs that decided not to use the authority provided for by P.L. 112-81 cite the
following reasons:
 the level of interest by small firms majority-owned by venture capital companies,
hedge funds, and private equity firms was unknown or anticipated to be small;
 the agency believed that small firms majority-owned by venture capital
companies, hedge funds, and private equity firms were not in need of SBIR
funds;
 the agency’s SBIR program was focused on early-stage research and small firms
majority-owned by venture capital companies, hedge funds, and private equity
firms focus on later stage R&D;
 given limited funding, the agency had an adequate number of qualified SBIR
applicants without expansion of the program to small firms majority-owned by
venture capital companies, hedge funds, and private equity firms; and
 the agency desired more information on the use of the authority by other
agencies.60
Additionally, GAO found that some federal agencies viewed the required written determination as
“potentially stringent,” necessitating rigorous analysis and evidence to support the use of the
authority.61 However, according to GAO, SBA officials do not approve or deny a written
determination and instead view it as “a notification letter, serving to inform SBA and Congress of
the agency’s plans.”62
The National Defense Authorization Act for Fiscal Year 2020 (P.L. 116-92) included a provision
establishing a pilot program under DOD’s SBIR program that would allow DOD to allocate up to
10% of its SBIR funding in a given fiscal year to small firms majority-owned by venture capital
companies, hedge funds, and private equity firms without making a written determination to SBA
or Congress. P.L. 116-92, however, limits the pilot program to entirely domestic majority-owned
small firms or those that meet certain requirements related to foreign ownership.

Congressionally Mandated Studies by National Academies of Sciences,
Engineering, and Medicine
Over 20 years, the National Academies of Sciences, Engineering, and Medicine has issued 19 consensus studies
assessing the SBIR and STTR programs of the five largest agencies with such programs—DOD, NIH, DOE, NSF,
and NASA—in addition to examining the overall effectiveness of the SBIR and STTR programs. Additionally, the
National Academies has issued three reports summarizing the proceedings of symposia and workshops focused on
the goals of the SBIR and STTR program to encourage the participation of minority and disadvantaged persons in
technological innovation and to foster the commercialization of federally funded R&D.
P.L. 106-554 mandated that federal agencies with an SBIR program budget over $50 mil ion in FY1999 (i.e., DOD,
NIH, DOE, NSF, and NASA) enter into a cooperative agreement with the National Academies to

conduct a comprehensive study of how the agency’s SBIR program has stimulated technological innovation
and used small businesses to meet federal R&D needs; and

make recommendations, as appropriate, with respect to improvements to an agency’s SBIR program.
The study was directed to include a review of the quality of research being conducted under the program, an
evaluation of the economic and noneconomic benefits achieved by the SBIR program, and an analysis of whether
federal agencies, in fulfil ing their procurement needs, are making sufficient effort to use small businesses that have
completed a Phase II award, among other areas.

P.L. 112-81extended the mandate and required DOD, NIH, DOE, NSF, and NASA to enter into a
cooperative agreement with the National Academies for an assessment of their SBIR program every four
years. Additionally, P.L. 112-81 directed the National Academies to conduct a comprehensive study of how
the STTR program has stimulated technological innovation and technology transfer.

National Academies’ reports on the SBIR and STTR programs are available at https://www.nap.edu/.
Improving Technology Commercialization and Trade-Offs Among
Program Objectives
A statutory goal of the SBIR and STTR programs is to foster the development and
commercialization of new technologies. Success in achieving this goal can take different forms.
For example, a technology could meet an agency need and be procured by that agency (e.g., a
specialized component or material for a NASA spacecraft), or a technology could fill a need in
the commercial marketplace (e.g., a biological process for producing enzymes and specialty
chemicals, including fragrances) or both. Over the years, Congress has included a number of
provisions focused on improving commercialization. For example, P.L. 112-81 made DOD’s
commercialization pilot program permanent (renaming it the Commercialization Readiness
Program) and P.L. 115-232 required all other agencies participating in the SBIR and STTR
programs to establish a Commercialization Assistance Pilot Program (the authority for the pilot
program expires on September 30, 2022). Activities under DOD’s Commercialization Readiness
Program increase connectivity between SBIR and STTR awardees, prime contractors, and DOD
acquisition officials while the Commercialization Assistance Pilot programs of other agencies
provide subsequent Phase II awards to select firms.
Some analysts have cautioned against placing too much emphasis on commercialization for
evaluating the success of the SBIR and STTR programs. These analysts argue that
commercialization is only one of the four overarching SBIR/STTR program goals, so too strong
of a focus on this one goal might diminish the emphasis on the others.63 A report by the National
Academies underscored how the SBIR/STTR program goals of stimulating innovation, meeting

federal research needs, increasing commercialization, and fostering diversity in innovation and
entrepreneurship “appear to be in conflict”:
A well-known challenge of innovation processes, however, is the gap between research
and commercialization. Individuals skilled at research tend to have much lower capability
for translating their research into products and then commercializing them, and vice
versa…. Many expressions of the program’s goals emphasize commercialization, which
could lead to a funding prioritization of projects that promise short-term commercialization
potential over those with potential for longer-term innovation potential…. Essentially the
program asks that agencies and awardees solve research problems, solve
commercialization problems, and diversify participation at the same time as a means to
address the overall societal mission of their agencies.64
Given SBIR/STTR agencies’ wide range of missions—from general missions, such as advancing
fields of science, to more specific missions, such as providing for the national defense—some
analysts have recommended that Congress continue to provide flexibility to agencies in the
operation of their programs.65 Other analysts have suggested that agencies should reorient their
SBIR and STTR programs “to focus more sharply on one of the program’s objectives:
commercializing innovations derived from federal R&D.”66 Such proponents and others have
offered a number of recommendations for increasing the commercialization success of agency
SBIR and STTR programs, including (1) requiring agencies to increase the weight of a project’s
commercialization potential in funding decisions; (2) increasing the recruitment of peer reviewers
with product and business development expertise; (3) allowing firms to use technical and
business assistance funds to hire in-house marketing and business expertise instead of requiring
assistance be provided by third party vendors; (4) centralizing management of an agency’s SBIR
and STTR programs; and (5) increasing topic flexibility in solicitations (i.e., ensuring that
agencies include a broad or “other” category in solicitations).67
Congress might consider statutory changes that alter or clarify the priority of commercialization
relative to the other goals of the SBIR and STTR programs (i.e., stimulating innovation, meeting
federal R&D needs, and fostering diversity). Based on recent academic studies, if Congress is
concerned with driving economic growth through the SBIR and STTR programs (as opposed to
supporting small businesses generally) it might consider changes that place more emphasis on
indicators of likely success such as firm age and growth potential as part of the application
process.

Small Business Research Programs: SBIR and STTR

Tracking Commercialization
Data collection has been and remains an issue for the SBIR and STTR programs according to
several reports. Federal agencies with SBIR and STTR programs are required to submit a variety
of data to SBA related to each small business that applies for or receives a Phase I or Phase II
award. SBA is required to collect this data and maintain it in a database for use in evaluating the
programs. Two data elements are relevant to assessing the transition of a Phase II award to Phase
III (i.e., commercialization).68 At the end of each Phase II award, the recipient is required to
report the following: (1) data on revenue from the sale of new products or services resulting from
R&D under the award; and (2) data on investments from any source other than the SBIR and
STTR programs to further the R&D conducted under the award.69 Additionally, recipients are
asked to voluntarily update the database annually for a period of five years after completion of the
Phase II award.70 Furthermore, when a small business applies for a new Phase II award, the small
business is required to update the database for any prior Phase II awards. According to the SBA,
they have a web-based portal where small businesses can submit relevant Phase III data to the
database; however, “because SBA cannot require companies to provide this information to the
site, this data has limited use in providing meaningful information regarding commercialization
success of Phase II awards.”71
The most common metric for assessing whether a Phase II award has been commercialized or
transitioned to Phase III is the sale of products, processes, or services resulting from the award.72
In general, participating federal agencies appear to view any sales as an indication that a Phase II
award has been successfully commercialized. However, the National Academies has raised
questions on what constitutes commercial success as indicated by sales:
What is the appropriate benchmark for sales? Is it any sales whatsoever, sufficient sales to
cover the costs of awards, sales that lead to breaking even on a project, or sales that reflect
a commercial level of success and viability? The latter at least would likely be different for
each project in each company.73
In 2016, the National Academies stated the following regarding the need for new data sources to
assess the SBIR and STTR programs:
Congress often seeks evidence about the effectiveness of programs or indeed about whether
they work at all. This interest has in the past helped to drive the development of tools such

68 As described by the Policy Directive, Phase III refers to work that derives from, extends, or completes an effort made
under prior SBIR and STTR funding agreements, but is funded by sources other than the SBIR and STTR programs.
Phase III includes the following: (1) the commercial application of SBIR and STTR funded R&D that is financed by
nonfederal sources of capital; (2) SBIR- and STTR-derived products or services intended for use by the federal
government, but funded by non-SBIR/STTR sources of federal funding; and (3) the continuation of R&D that has been
competitively selected using peer review, funded by non-SBIR/STTR sources of federal funding.

71 Email from SBA to CRS, March 12, 2019.
72 There is some variability in the definition of sales among the studies examined. For example, the National
Academies studies define sales to include the sale of products, processes, or services resulting from a SBIR/STTR
award, in addition to revenue associated with the licensing of a technology resulting from a SBIR/STTR award.
However, studies performed on behalf of DOD define sales to include the sale of new products or services, follow-on
R&D contracts, royalties from the licensing of technologies developed under Phase II awards, sales by licensees of
Phase II technologies, and sales by spin-out companies commercializing Phase II technologies.

as the Company Commercialization Record database at DOD. However, in the long term
the importance of tracking lies in its use to support program management. By carefully
analyzing outcomes and associated program variables, program managers should be able
to manage more successfully. We have seen significant limitations to all of the available
data sources.74
Additionally, the National Academies noted that one of the primary means of collecting
information—surveying firms that received SBIR and STTR awards—“involve[s] multiple
sources of potential bias that can skew results in different directions.”75 These potential biases
include the following: (1) successful and more recently funded firms are more likely to respond;
(2) success is self-reported; (3) failed firms are difficult to contact; (4) not all successful projects
are captured; (5) some firms are unwilling to fully acknowledge the SBIR and STTR contribution
to project success; and (6) a lag time in commercialization.76 Regarding lag time, the National
Academies added
Not only do outcomes lag awards by a number of years, but also the lag itself is highly
variable. Some companies have sales within 6 months of award conclusion; others take
decades. In addition, often the biggest impacts take many years to peak even after products
have reached markets.77
With these caveats about data collection, the National Academies and others have found that
about half of SBIR and STTR awards at DOD, NIH, DOE, NSF, and NASA are commercialized
as measured by the generation of any sales. For example:
 A 2019 study of DOD’s SBIR and STTR programs found that 58% of recipients
of DOD Phase II SBIR/STTR awards made between FY1995 and FY2012 had
been successfully commercialized by 2018. The study surveyed more than 4,400
companies that had received nearly 17,000 awards. The small businesses
surveyed reported $121 billion in total combined sales.78
 In 2018, the National Cancer Institute (NCI), an institute of the National
Institutes of Health, released a study examining outcomes associated with all
Phase II SBIR/STTR awards made by the NCI between FY1998 and FY2010. Of
the 648 awards examined, 53% were commercialized as measured by the
generation of any sales. The small businesses surveyed reported combined total
sales of $9.1 billion.79
 A 2016 report by the National Academies assessed outcomes associated with
DOE Phase II SBIR/STTR awards made between FY2001 and FY2010.
According to the report, 49% of the 269 Phase II awards examined generated
revenue from the sale of products or services associated with the SBIR/STTR

award. Additionally, 78% of the 269 Phase II awards attracted additional
investment.80
Multiple Award Recipients and Role in Commercialization
Another topic that has received attention from Congress and others is the role of multiple award
recipients (i.e., small firms that receive multiple SBIR and STTR awards) in the SBIR and STTR
programs. Some experts express concern that such firms depend on the SBIR and STTR
programs for a disproportionate share of their revenue, that they may not seek revenue outside of
the programs, and that they have a poor track record of commercialization. According to the
National Academies, studies examining the commercialization record of multiple award
recipients “present conflicting evidence” and do not assess the performance of these firms in
“important non-commercial outcomes such as procurement and basic research.”81 Further, the
National Academies stated
Firms that win multiple awards may differ from one another in several important ways. For
instance, a frequent winner that is struggling to commercialize due to the non-incremental
nature of its technology is quite different from one that acquires frequent grants as part of
its business model. Second, firms may establish long SBIR/STTR track records as part of
a mutually symbiotic relationship with the funding agency, especially in cases in which
SBIR/STTR winners are uniquely equipped to meet specific procurement needs. These
firms develop deep relationships with their funders over years of SBIR/STTR activity
within a single agency. This vertical accumulation of awards within a single agency may
lead firms to help expand agency capacities well beyond what a typical SBIR/STTR
awardee can accomplish. On the other hand, more horizontally oriented firms may be
searching for awards across multiple agencies to match their own specific technologies or
to take advantage of an established familiarity with the application process.82
For some who view the SBIR and STTR programs primarily as a means to stimulate economic
growth, multiple award recipients should not be the focus of the programs. Instead, such
advocates argue that the SBIR and STTR programs should be focused on growth-oriented small
firms, which typically are younger firms or start-ups.83 According to the National Academies
While the barriers and transactions costs facing small businesses are well understood as
justifications for government intervention, it has become clear that younger small
businesses are the dominant drivers of traditional metrics of economic growth
(Haltiwanger, Jarmin, and Miranda, 2013). Firm age, therefore, is an important moderating
variable in assessments of any program that aims to support small firms.84
In 2011, Congress responded to concerns over multiple award recipients by requiring each federal
agency with an SBIR or STTR program to establish a system for measuring the success of a small
business in commercializing its SBIR/STTR-funded research.85 To address the requirement, SBA,

in conjunction with federal agencies, created a commercialization benchmark for the purpose of
determining eligibility for additional SBIR and STTR awards.86 According to SBA, the
commercialization benchmark applies to SBIR and STTR Phase I applicants that have received
16 or more Phase II awards over the past 10 fiscal years, excluding the last two fiscal years. To be
eligible for a new Phase I award, such small businesses are required to have achieved a minimum
level of commercialization activity resulting from work performed under their past Phase II
awards. Specifically, the small business “must have received, to date, an average of at least
$100,000 of sales and/or investments per Phase II award received, or have received a number of
patents resulting from the SBIR work equal to or greater than 15% of the number of Phase II
awards received [by the company] during the period.”87 However, according to GAO, “SBA and
the participating agencies have assessed small businesses against the Commercialization
Benchmark only once, in 2014, because of challenges in collecting and verifying the accuracy of
data.”88 GAO recommended that SBA work with participating agencies to (1) to improve the
reliability of its SBIR and STTR award data; and (2) implement the Commercialization
Benchmark or, if that is not feasible, revise the benchmark so that it can be implemented.89
According to the SBIR and STTR program website, “As of April of 2021, SBA is enforcing the
Commercialization Benchmark and is compiling a list of companies that will be deemed
ineligible to submit a proposal for a new Phase I (or Direct-to-Phase II) award due to failure to
meet the Commercialization Benchmark requirement.”90 It remains unclear, however, if concerns
about the reliability and quality of SBIR and STTR award data has been resolved.
Fostering Diversity in Technological Innovation
Another statutory goal of the SBIR and STTR program is to foster and encourage the
participation of minority and disadvantaged persons in technological innovation. Assessments of
agency SBIR and STTR programs by the National Academies and others have consistently found
that federal agencies are not effectively increasing the number of women-owned or minority-
owned small businesses applying for the SBIR or STTR programs and that women-owned or
minority-owned small businesses that have applied, in general, have been less successful in the
application process.91 Some Members of Congress have also been concerned about the
geographic diversity of small businesses participating in the programs (i.e., ten states received the
majority of SBIR and STTR awards and funding). Congressional efforts have focused primarily
on increasing outreach efforts associated with the SBIR and STTR programs. For example, the
Federal and State Technology (FAST) Partnership Program provides outreach, financial support,
and technical assistance to small businesses with a “particular emphasis on helping women,

socially/economically disadvantaged individuals, and applicants from underrepresented or rural
areas compete in the SBIR and STTR programs.”92
In 2013, the National Academies hosted a workshop to examine the diversity and inclusion
challenges associated with the SBIR and STTR programs. Individuals participating in the
workshop offered a number of suggestions which fell into three broad categories—expanding the
pool of applicants, eliminating barriers in award applications and selection, and providing greater
education and support for entrepreneurship training and commercialization efforts.93 Examples of
the suggestions offered include the following:
 Improve outreach through existing programs and partnerships that serve
disadvantaged populations.
 Use the funds from the administrative pilot program for enhancing program
management, improving outreach, and reducing barriers to completing
applications.
 Focus on the increasing the pipeline of talented women and minorities to advance
program diversity.
 Institute a federal “phase zero” program similar to programs in Florida, Vermont,
and other states that award applicants funds to hire consultants to help prepare
stronger proposals, including technology development and commercialization
strategies.
 Require a one-page commercialization plan for Phase I applications except for
applications focused on basic research.94
Agency Compliance with Mandatory Minimum Expenditures
Federal agencies participating in the SBIR and STTR programs are required to expend at least a
statutorily defined minimum percentage of their extramural research funding annually. While
agency compliance has improved over the years, some issues remain.
In a September 2013 report, GAO found that 8 of the 11 agencies participating in the SBIR
program and 4 of the 5 agencies participating in the STTR program failed to consistently comply
with spending requirements for FY2006-FY2011.95 In June 2014, GAO reported that three
agencies failed to comply with the SBIR requirement and three failed to comply with the STTR
requirement in FY2012.96 In May 2017, GAO found that 2 of the 11 SBIR agencies and 1 of the 5
STTR agencies failed to meet their spending requirements for FY2015 or their compliance could
not be determined.97 And in its FY2018 annual report SBA reported that the majority of federal

agencies participating in the SBIR program and the STTR program either failed to comply with
the mandatory minimum expenditure levels or compliance could not be determined.98
Among the factors affecting agencies’ failure to comply with the mandatory minimum
expenditure levels are challenges in calculating the amount to be set aside; the enactment of
appropriations after the start of the fiscal year; and differing agency interpretations of the
statutory requirement for “expended.”
Calculation of Extramural Research Funding and Set-Aside
The SBIR and STTR set-asides are based on an agency’s extramural budget for research or
research and development.99 The calculation of the amount of this budget can be complex for
some agencies. For example, several agencies support extramural R/R&D funding through
multiple subunits.100 In addition, agency extramural R/R&D funding can come from more than
one appropriations account, and such accounts can include activities and programs that are not
extramural R/R&D.101 Accordingly, each agency must determine its extramural R/R&D budgets
using a methodology that identifies extramural R/R&D funding as well as what is to be excluded
from this amount.102
Given the complexity of this challenge, Congress required each agency to report its methodology
to SBA annually within four months of enactment of its appropriation.103 The Policy Directive
states
If the minimum amount was not met, the agency must provide the reasons why and an
explanation of how the agency plans to meet the requirement in the future. Agencies may
provide an explanation of the specific budgeting process their agency uses to allocate funds
for the SBIR/STTR programs and describe any issues they may see with the compliance
determination procedure. Agencies may also indicate obligations made in the reporting
year using prior fiscal years of appropriation within available funding obligation periods.104
According to GAO, over the years, many agencies have submitted these reports to SBA too late
for SBA to provide timely feedback to the agencies after reviewing their methodologies and
exclusions. For example, in 2017 GAO found that 5 of the 11 agencies participating in the SBIR
and STTR programs submitted their required methodology reports on time.105 Additionally, in

98 SBA, Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) Programs
Annual Report for Fiscal Year 2018
, pp. 32-45.
99 “Extramural budget” is defined as “the sum of the total obligations for R/R&D minus amounts obligated for R/R&D
activities by employees of a federal agency in or through government-owned, government-operated facilities. See
Policy Directive,
p. 58.
100 For example, the Department of Energy extramural R/R&D budget includes funding in the Office of Science, Office
of Nuclear Energy, Office of Electricity Delivery and Energy Reliability, Office of Energy Efficiency and Renewable
Energy, Office of Environmental Management, Office of Fossil Energy, National Nuclear Security Administration, and
Advanced Research Projects Agency—Energy.
101 For example, more than one National Science Foundation account has extramural R&D funding as well as funding
that is not R&D.
102 Agencies are required to exclude, for example, subunits in the intelligence community from their extramural R&D
budget.

2019, SBA reported that DOD had not provided SBA with the total R/R&D extramural funds the
agency obligated in FY2017 and that some DOD components had not submitted the required
reporting methodology.106
Another factor affecting the calculation of SBIR funding is that, in practice, agencies generally
calculate their SBIR set-asides based on their extramural R/R&D budgets and not on their
extramural R/R&D obligations as required by statute.107 An agency’s extramural R/R&D budget
reflects its spending plans for a fiscal year, whereas an agency’s extramural R/R&D obligations
reflect the amount of funds an agency actually obligates108 to spending in a fiscal year; a final
obligation figure for extramural R/R&D may not be calculable until the end (or very close to the
end) of a fiscal year. Thus, an agency’s extramural R/R&D obligations (and the minimum SBIR
set-aside amount) may be higher or lower than the level the agency anticipated in its extramural
R/R&D budget.
Enactment of Appropriations after Start of Fiscal Year
Enactment of appropriations after the start of a fiscal year may also affect the ability of agencies
to expend SBIR/STTR funds at the required level in that fiscal year. For example, if an agency
plans its expenditures around a level specified in a continuing resolution but then receives a
higher final appropriations, then expenditure of the additional amount to be set aside for
SBIR/STTR in that fiscal year may be difficult.
Agency Views of Requirement to “Expend” Funds
Some agencies participating in the SBIR and STTR programs receive multiyear appropriations
that allow funds to be carried over from one year to the next. Some program managers at such
agencies have indicated that they “may choose to spend their SBIR funds over multiple fiscal
years to help spend the funds properly and efficiently.” Others have indicated that they “might not
spend enough to meet the spending requirement in the current fiscal year, although the carried-
over funds may help the agency meet or exceed the spending requirement in the following
year.”109
Congress might consider statutory changes that alter or clarify how agencies are to determine the
amount to be set aside each year for SBIR and STTR, and whether those amounts must be spent
in the same fiscal year; obligated, in whole or in part, for expenditure over multiple fiscal years;
or expended without restriction to any given period.

legal liability by virtue of actions on the part of the other party beyond the control of the United
States. Payment may be made immediately or in the future. An agency incurs an obligation, for
example, when it places an order, signs a contract, awards a grant, purchases a service, or takes
other actions that require the government to make payments to the public or from one government
account to another.

SBA Delays in Meeting Statutory Reporting Requirements
The Small Business Act has required the SBA to report annually to Congress on the SBIR and
STTR programs since the inception of these programs. SBA compliance with this requirement has
been an ongoing issue. According to GAO, SBA issued its FY2012 report to Congress in
November 2014 and its FY2013 report in March 2016.110 The annual reports for FY2016 and
FY2017 were submitted in 2019 and the FY2018 report was submitted in 2021. As of the date of
this report, the SBA had not yet delivered its FY2019 report. Failure to produce these reports on a
timely basis may impede Congress’s exercise of its oversight responsibilities.
Among the issues that may affect the timeliness of SBA reporting are SBIR/STTR agencies’
delays in providing data to the SBA and adequate staffing levels at SBA devoted to producing the
report.111 For example, in the FY2017 SBIR/STTR annual report SBA stated
SBA received the DOD’s last FY17 Annual Report data upload on December 19, 2018,
which is over nine months late. As such, this limited the amount of time available to analyze
and validate the DOD data. It should be noted, the other 10 Participating Agencies
submitted the Annual Report information (including the methodology report) to SBA in a
timely fashion.112
Concerns About Fraud, Waste, and Abuse
Identification and elimination of fraud, waste, and abuse in the SBIR and STTR programs have
been abiding concerns of Congress. In 2011, Congress sought to address such concerns by
directing SBA to amend its Policy Directive to include measures to prevent fraud, waste, and
abuse.113 The Policy Directive requires federal agencies with SBIR or STTR programs to
implement the following minimum requirements:
 Require certifications from awardees at the time of award, after the award period,
and during the award funding lifecycle.
 Include on the agency’s SBIR and STTR program webpage, and in program
solicitations, information explaining how an individual can report fraud, waste,
and abuse.
 Designate at least one individual in the agency to serve as the liaison between the
SBIR and STTR program, the agency’s Office of Inspector General (OIG), and
the agency’s Suspension and Debarment Official (SDO) and ensure that inquiries
regarding fraud, waste, and abuse are referred to the OIG and, if applicable, the
SDO.
 Include on the agency’s SBIR and STTR program web page information
concerning successful prosecutions of fraud, waste, and abuse in the programs.
 Establish a written policy requiring all personnel involved with the SBIR and
STTR programs to notify the OIG if they suspect fraud, waste, and abuse and
ensure this policy is communicated to all SBIR and STTR personnel.

110 Ibid., p. 20.
111 Per the Policy Directive, agencies participating in the SBIR and STTR programs are required to submit their data to
SBA by March 15 each year for the previous fiscal year (for example, data for FY2019 was due to SBA by March 15,
2020).

Small Business Research Programs: SBIR and STTR

 Create or maintain an adequate system to enforce accountability through
suspension and debarment, fraud referrals, or other efforts to deter wrongdoing
and promote integrity.
 Ensure compliance with the eligibility requirements of the programs and the
terms of SBIR and STTR funding agreements.
 Work with the agency’s OIG with regard to its efforts to establish fraud detection
indicators, coordinate the sharing of information between federal agencies, and
improve education and training to SBIR and STTR program officials, applicants,
and awardees.
 Develop policies and procedures to avoid funding essentially equivalent or
duplicative work already funded by the same or another agency.
 Consider enhanced reporting requirements associated with SBIR and STTR
funding agreements.114
Additionally, Congress required GAO to publish a report every four years on agency efforts to
combat fraud, waste, and abuse. In June 2021, the most recent GAO report found
The 11 agencies participating in the Small Business Innovation Research (SBIR) and Small
Business Technology Transfer (STTR) programs largely implemented the Small Business
Administration’s (SBA) 10 minimum requirements for preventing fraud, waste, and abuse
in the programs. Most agencies fully implemented at least eight of the 10 requirements and
partially implemented the others; one agency, NASA, fully implemented all 10…. Multiple
agencies did not fully implement certain requirements, such as ones to collect eligibility
certifications and to have a process for tracking referrals to Offices of Inspector General
(OIG). Agency officials gave various reasons for partially implementing requirements,
such as their belief that they had met a requirement’s intent through other actions.
However, because agencies did not fully implement all 10 requirements, they may face
difficulties. For example, by not collecting program eligibility certifications, agencies may
find it complicated to hold individuals and businesses accountable if they misrepresent
their eligibility for SBIR and STTR awards.115
A 2019 report by the Department of Health and Human Services’ OIG found that “meeting the
minimum requirements [contained in the policy directive] does not fulfill OIG’s outstanding
recommendations, nor does it appear that it sufficiently prevents fraud, waste, and abuse in the
SBIR program.”116
Other Issues
Congress may explore a number of other issues that have been raised by various stakeholders or
examined by GAO as it continues oversight and examines the possible reauthorization of the
SBIR and STTR programs in 2022. For example, some have advocated for an increase in the
maximum size of awards, especially awards associated with the research and development of

biotechnology.117 Others have expressed concern over a perceived lack of resources devoted to
SBA oversight and administration of the programs.118 Another potential issue is timeliness. In
September 2020, GAO issued a report examining the timelines associated with the review and
issuance of awards by federal agencies in FY2019. According to GAO, more than three-quarters
of the agencies with SBIR and STTR programs issued such awards within the required
timeframes; however, GAO did not evaluate the time between Phase I and subsequent Phase II
awards, which some have raised as important for increasing the potential for
commercialization.119
