Summary

The length of time a congressional staff member spends employed in a particular position in Congress—or congressional staff tenure—is a source of recurring interest to Members, staff, and the public. A congressional office, for example, may seek this information to assess its human resources capabilities, or for guidance in how frequently staffing changes might be expected for various positions. Congressional staff may seek this type of information to evaluate and approach their own individual career trajectories. This report presents a number of statistical measures regarding the length of time House committee staff stay in particular job positions. It is designed to facilitate the consideration of tenure from a number of perspectives.

This report provides tenure data for a selection of 13 staff position titles that are typically used in House committee offices, and information on how to use those data for different purposes. The positions include Chief Clerk, Chief Counsel, Communications Director, Counsel, Deputy Staff Director, Minority Professional Staff Member, Minority Staff Director, Press Secretary, Professional Staff Member, Senior Professional Staff Member, Staff Assistant, Staff Director, and Subcommittee Staff Director. House committee staff tenure data were calculated as of March 31, for each year between 2006 and 2016, for all staff in each position. An overview table provides staff tenure for selected positions for 2016, including summary statistics and information on whether the time staff stayed in a position increased, was unchanged, or decreased between 2006 and 2016. Other tables provide detailed tenure data and visualizations for each position title.

Between 2006 and 2016, staff tenure, based on the trend of the median number of years in the position, appears to have increased by six months or more for staff in nine position titles in House committees. The median tenure was unchanged for four positions. These findings may be consistent with overall workforce trends in the United States.

Pay may be one of many factors that affect an individual's decision to remain in or leave a particular job. House committee staff holding positions that are generally lower-paid typically remained in those roles for shorter periods of time than those in generally higher-paying positions. Lower-paying positions may also be considered entry-level roles; if so, tenure for House committee employees in these roles appears to follow national trends for other entry-level jobs, which individuals hold for a relatively short period of time. Those in more senior positions, where a particular level of congressional or other professional experience is often required, typically remained in those roles comparatively longer, similar to those in more senior positions in the general workforce.

Generalizations about staff tenure are limited in some ways, because each House committee serves as its own hiring authority. Variations from office to office, which might include differences in job duties, work schedules, office emphases, and other factors, may limit the extent to which data provided here might match tenure in another office. Direct comparisons of congressional employment to the general labor market may have similar limitations. Change in committee leadership, for example, may cause staff tenure periods to end abruptly and unexpectedly.

Staff Tenure in Selected Positions in House Committees, 2006-2016

Introduction

The length of time a congressional staff member spends employed in Congress, or job tenure, is a source of recurring interest among Members of Congress,1 congressional staff, those who study staffing in the House and Senate,2 and the public. There may be interest in congressional tenure information from multiple perspectives, including assessment of how a congressional office might oversee human resources issues, how staff might approach a congressional career, and guidance for how frequently staffing changes may occur in various positions. Others might be interested in how staff are deployed, and could see staff tenure as an indication of the effectiveness or well-being of Congress as an institution.3

This report provides tenure data for 13 staff position titles that are typically used in House committees, and information for using those data for different purposes. The positions include the following:

Data Source and Concerns

Publicly available information sources do not provide aggregated congressional staff tenure data in a readily retrievable or analyzable form. Data in this report are based on official House pay reports, from which tenure information arguably may be most reliably derived, and which afford the opportunity to use complete, consistently collected data. Tenure information provided in this report is based on the House's Statement of Disbursements (SOD),4 published quarterly by the House Chief Administrative Officer, as collated by LegiStorm, a private entity that provides some congressional data by subscription.5

House committee staff tenure data were calculated for each year between 2006 and 2016. Annual data allow for observations about the nature of staff tenure in House committees over time. For each year, all staff with at least one week's service6 on March 31 were included. All employment pay dates from October 2, 2000, to March 24 of each reported year are included in the data.

Utilizing official salary expenditure data from the House may provide more complete, robust findings than other methods of determining staff tenure, such as surveys; the data presented here, however, are subject to some challenges that could affect the interpretation of the information presented. Tenure information provided in this report may understate the actual time staff spend in particular positons, due in part to several features of the data.

Figure 1 provides potential examples of congressional staff, identified as Jobholders A-D, in a given position.7 Some individuals, represented as Jobholder A, may have an unknown length of prior service before October 2, 2000, when the data begin. In the data captured for this report, no jobholders fall into this category. The earliest date at which House committee staff included in this report received pay was October 4, 2000. Thus, the tenure periods of all staff for which data are provided completely begin within the observed period of time; some tenure periods, as represented by Jobholders B and C, also end within the observed period. The data last capture those who were employed in House committees as of March 31, 2016, represented as Jobholder D, and some of those individuals likely continued to work in the same roles after that date.

Note: No staff in positions identified in this report received pay before October 4, 2000; therefore, no staff in this report fall into the Jobholder A category.

Data provided in this report represent an individual's consecutive time spent working in a particular position in a House committee. They do not necessarily capture the overall time worked in a House office or across a congressional career. If a person's job title changes, for example, from staff assistant to professional staff member, the time that individual spent as a staff assistant is recorded separately from the time that individual spent as a professional staff member. If a person stops working for the House for some time, that individual's tenure in his or her preceding position ends, although he or she may return to work in Congress at some point. No aggregate measure of individual congressional career length is provided in this report.

Other data concerns arise from the variation across committees and lack of other demographic information about staff.

Potential differences might exist in the job duties of positions with the same or similar title, and there is wide variation among the job titles used for various positions in congressional offices. The Appendix provides the number of related titles included for each job title for which tenure data are provided. Aggregation of tenure by job title rests on the assumption that staff with the same or similar title carry out the same or similar tasks. Given the wide discretion congressional employing authorities have in setting the terms and conditions of employment, there may be differences in the duties of similarly titled staff that could have effects on the interpretation of their time in a particular position.

As presented here, tenure data provide no insight into the education, age, work experience, pay, full- or part-time status of staff, or other potential data that might inform explanations of why a congressional staff member might stay in a particular position.

Presentation of Tenure Data

Tables in this section provide tenure data for selected positions in House committees and detailed data and visualizations for each position. Table 1 provides a summary of staff tenure for selected positions since 2006. The data include job titles, average and median years of service, and grouped years of service for each positon. The "Trend" column provides information on whether the time staff stayed in a position increased, was unchanged, or decreased between 2006 and 2016.8 Table 2-Table 14 provide information on individual job titles over the same period.

In all of the data tables, the average and the median length of tenure columns provide two different measures of central tendency,9 and each may be useful for some purposes and less suitable for others. The average represents the sum of the observed years of tenure, divided by the number of staff in that position. It is a common measure that can be understood as a representation of how long an individual remains, on average, in a job position. The average can be affected disproportionately by unusually low or high observations. A few individuals who remain for many years in a position, for example, may draw the average tenure length up for that position. A number of staff who stay in a position for only a brief period may depress the average length of tenure. Another common measure of central tendency, the median, represents the middle value when all the observations are arranged by order of magnitude. The median can be understood as a representation of a center point at which half of the observations fall below, and half above. Extremely high or low observations may have less of an impact on the median.


Using Position Data Tables

Position data are found in Table 2 through Table 14, and each of these tables provides information on a separate job title.

Section A provides the number of individuals with a particular job title and provides a chart that illustrates this information. The number of staff over time might offer insight into the operations and activities in House committees, or the House more generally.

Section B provides the annual average and median tenures for that position. Average and median are reported for each position because one measure may be more appropriate than the other, depending upon which data are being examined and for what purpose.

Section C provides the percentages of staff who had been working in that job for up to one year, one to five years, and five or more years. Below the tables in Section C, visualization provides percentages for three selected years: 2006, 2011, and 2016.

Section D provides more detailed information for staff in each position over the past five years. For the years 2012-2016, the percentage of staff in each job is displayed in annual increments for 1-10 years of service, in addition to categories for less than a year of service and more than 10 years. The average and median for each annual increment over this five-year period is also provided. The figure at the bottom of Section D visually displays this information for 2012, 2014, and 2016. Because the available data begin in October 2000, at least 10 years of staff tenure data are available by 2012, which enables more detailed information to be provided about those who have worked between five and 10 years.

Individual elements of data in this report may provide more useful insights when compared to other data provided. Combined, certain statistics may be used to infer changes in tenure over time or address other questions of interest. The overall average and median for a position found in Table 1, for example, might be compared to the equivalent measures in a particular year from Section B of that job position table, and could illustrate how typical or atypical average or median tenure in that year is. The aggregate average or median distributions provided in the "% by Position" columns of Table 1 could similarly be used in comparison to Section C of a job position table to evaluate the percentage distributions for a given year.

The tenure percentage distributions may be helpful for determining continuity or turnover patterns for job positions. A broad, overall measure of turnover is provided in Table 1, but more information can be found in the job position tables, in Sections C and D. A position with a large proportion of staff remaining for five or more years, relative to the proportion of staff remaining for under one year, for example, could indicate a position that jobholders typically remain in for longer periods of time. Comparing these distributions over time could indicate that a job is becoming more stable, or, conversely, that greater turnover is occurring. When performing any assessment with these percentages, it is important to consider the number of staff in a particular role; a percentage change may seem dramatic when the overall number of staff is small, but reflect changes of only one or a few individuals. . It may be helpful to convert percentages to number of staff, by multiplying the percentage by the staff count in Section A for the corresponding year. Although this report does not measure staff tenure in terms of "cohorts" who all begin during a certain year, this type of information may be inferred from the detailed annual breakdowns provided in Section D. A read of Section D diagonally—down one row to the next calendar year and right one column to the next year of service—may help address questions related to tenure for staff hired in, or working during, a particular year.

Assessing Tenure Data

Generalizations about staff tenure are limited in at least three potentially significant ways, including the following:

Considering tenure in isolation from demographic characteristics of the congressional workforce might limit the extent to which tenure information can be assessed. Additional data on congressional staff regarding age, education, and other elements would be needed for this type of analysis, and are not readily available at the position level. Finally, since each House committee serves as its own hiring authority, variations from committee to committee, which for each position may include differences in job duties, work schedules, office emphases, and other factors, may limit the extent to which data provided here might match tenure in a particular office. Despite these caveats, a few broad observations can be made about staff in House committees.

Between 2006 and 2016, staff tenure, based on the trend of the median number of years in the position, appears to have increased by six months or more for staff in nine position titles10 in House committees. The median tenure was unchanged11 for four positions.12 This may be consistent with overall workforce trends in the United States.13Although pay is not the only factor that might affect an individual's decision to remain in or leave a particular job, staff in positions that generally pay less typically remained in those roles for shorter periods of time than those in higher-paying positions.14 Some of these lower-paying positions may also be considered entry-level positions in some House committees; if so, House office employees in those roles appear to follow national trends for others in entry-level types of jobs, remaining in the role for a relatively short period of time.15 Similarly, those in more senior positions, which often require a particular level of congressional or other professional experience, typically remained in those roles comparatively longer, similar to those in more senior positions in the general workforce.

Notes: As used in this report, "trend" is an indication of the general course of median staff tenure in each position over time, based on a linear regression model. The resulting trend line (which is available to congressional staff upon request), could increase, decrease, or remain unchanged. Each position's trend line varies between 2006 and 2016, but the variability demonstrates negligible change for most positions. To distinguish positions with readily measurable changes in their tenure, a benchmark of change in trend is set to an increase or decrease of six months' tenure over the 11 years observed. "Unchanged" in this context is defined as an increase or decrease in the median trend of tenure of fewer than six months between 2006 and 2016.

Appendix. Job Title Categories

There is wide variation among the job titles used for various positions in congressional offices. Between October 2000 and March 2016, House and Senate pay data provided 13,271 unique titles under which staff received pay. Of those, 1,884 were extracted and categorized into one of 33 job titles used in CRS Reports about Member or committee offices. Office type was sometimes related to the job titles used. Some titles were specific to Member (e.g., District Director, State Director, and Field Representative) or committee (positions that are identified by majority, minority, or party standing, and Chief Clerk) offices, while others were identified in each setting (Counsel, Scheduler, Staff Assistant, and Legislative Assistant).

Other job title variations reflect factors specific to particular offices, since each office functions as its own hiring authority. Some of the titles may distinguish between roles and duties carried out in the office (e.g., chief of staff, legislative assistant, etc.). Some offices may use job titles to indicate degrees of seniority. Others might represent arguably inconsequential variations in title between two staff members who might be carrying out essentially similar activities. Examples include the following:

The titles used in this report were used by most House committees, but a number of apparently related variations are included to ensure inclusion of additional offices and staff. Table A-1 provides the number of related titles included for each position used in this report or related CRS Reports on staff tenure. A list of all titles included by category is available to congressional offices upon request.

http://www.legistorm.com/. LegiStorm provides data from October 1, 2000, see "Congressional Salaries FAQ," https://www.legistorm.com/salaries/faq.html#How_far_back_does_your_salary_information_go_. Congressional staff pay data are taken by LegiStorm from the semiannual Report of the Secretary of the Senate and the SOD. LegiStorm provided staff and pay records to the Congressional Research Service covering the period October 1, 2000-March 31, 2016, for the Senate and House in a series of relational data files that combined information about staff from both chambers. LegiStorm data contained information on 170,108 individuals, including current and former congressional staff, Members of Congress, other government officials, and others; of those, 4,618 were employed by a House committee between 2000 and 2016. The LegiStorm-aggregated House and Senate pay data contained more than 1.23 million records, including 112,189 records of staff working for House committees that were used to derive tenure information provided in this report.

Staff were included if they were on payroll on March 31 of each year and had at least one week of service in the position. Staff with six or fewer days (0.0167 years) of service in the position on March 31 of each year were excluded.

Figure 1 provides a simplified view of congressional staff tenure; other possibilities for jobholder tenure periods exist but are not represented in this illustration. Some staff starting at the same time as Jobholder B might not have ended their service before March 31, 2016, and might have continued in the position after that date. No staff in positions identified in this report received pay before October 4, 2000; therefore, no staff in this report fall into the Jobholder A category.

As used in this report, "trend" is an indication of the general course of median staff tenure in each position over time, based on a linear regression model. The resulting trend line (which is available to congressional staff upon request), could increase, decrease, or remain unchanged. Each position's trend line varies between 2006 and 2016, but the variability demonstrates negligible change for most positions. To distinguish positions with readily measurable changes in their tenure, a benchmark of change in trend is set to an increase or decrease of six months' tenure over the 11 years observed. "Unchanged" in this context is defined as an increase or decrease in the median trend of tenure of fewer than six months between 2006 and 2016.

A measure of central tendency is a single value that represents the middle of a data distribution, or list of numbers. It is often used to summarize that set of data. There are a variety of ways to measure central tendency, including, but not limited to, the average and median.

Data provided by the Bureau of Labor Statistics (BLS) suggest that the tenure trend in the U.S. labor force for workers aged 25 and over is largely unchanged between 2006 and 2016. See U.S. Department of Labor, Bureau of Labor Statistics, Table 1. Median years of tenure with current employer for employed wage and salary workers by age and sex, selected years, 2006-16, Washington, DC, September 22, 2016, http://www.bls.gov/news.release/tenure.t01.htm. See also, Ibid, Employee Tenure Summary, http://www.bls.gov/news.release/tenure.nr0.htm. Staff working in congressional offices likely appear to be fairly representative of the general workforce in the United States. Nevertheless, direct comparisons of congressional employment to the general labor market may have limitations. Unlike congressional tenure data provided in this report by title, for example, BLS data are based on the entire U.S. workforce, and determine tenure statistics based on the time an employee spends with an employer rather than time in one specified job title. Comparisons between the two sets of employment tenure information should be drawn with care.

Those staff positions that typically earn a lower salary than others, including Counsel, and Staff Assistant, may be seen in some House committees as entry level, but both pay data (see ibid.) and tenure data presented in this report suggest that this might not be a consistent practice in every committee.
