Perhaps most prominently, the Elementary and Secondary Education Act (ESEA), as amended by the Every Student Succeeds Act (ESSA; P.L. 114-95), requires the use of test-based educational accountability systems in states and specifies the requirements for the assessments that states must incorporate into state-designed educational accountability systems. These requirements are applicable to states that receive funding under Title I-A of the ESEA. More specifically, to receive Title I-A funds, states must agree to assess all students annually in grades 3 through 8 and once in high school in the areas of reading and mathematics. Students are also required to be assessed in science at least once within each of three specified grade spans (grades 3-5, 6-9, and 10-12). The results of these assessments are used as part of a state-designed educational accountability system that determines which schools will be identified for support and improvement based on their performance. The results are also used to make information about the academic performance of students in schools and school systems available to parents and other community stakeholders.\nAs student assessments continue to be used for accountability purposes under the ESEA as well as in many other capacities related to federal programs (e.g., for identifying students eligible to receive extra services supported through federal programs), this report provides Congress with a general overview of assessments and related issues. It discusses different types of educational assessments and uses of assessment in support of the aims of federal policies. The report aims to explain basic concepts related to assessment in accessible language, and it identifies commonly discussed considerations related to the use of assessments. The report provides background information that can be helpful to readers as they consider the uses of educational assessment in conjunction with policies and programs. This report accompanies CRS Report R45049, Educational Assessment and the Elementary and Secondary Education Act, by Rebecca R. Skinner, which provides a more detailed examination of the assessment requirements under the ESEA.\nThe following topics are addressed in this report:\nPurposes of Assessment: Assessments are developed and administered for different purposes: instructional, diagnostic, predictive, and evaluative. Increasingly, states are attempting to use assessments for these purposes within a balanced assessment system. A balanced assessment system often incorporates various assessment types, such as formative and summative assessments. Formative assessments are used to monitor progress toward a goal and summative assessments are used to evaluate the extent to which a goal has been achieved. \nTypes of Tests: Educational assessments can be either norm-referenced tests (NRTs) or criterion-referenced tests (CRTs). An NRT is a standardized test that compares the performance of an individual student to the performance of a large group of students. A CRT compares the performance of an individual student to a predetermined standard or criterion. The majority of tests used in schools are CRTs. The results of CRTs, such as state assessments required by Title I-A of the ESEA, are usually reported as scaled scores or performance standards. A scaled score is a standardized score that exists along a common scale that can be used to make comparisons across students, across subgroups of students, and over time. A performance standard is a generally agreed upon definition of a certain level of performance in a content area that is expressed in terms of a cut score (e.g., basic, proficient, advanced).\nTechnical Considerations in Assessment: The technical qualities of assessments, such as validity, reliability, and fairness, are considered before drawing conclusions about assessment results. Validity is the degree to which an assessment measures what it is supposed to measure. Reliability is a measure of the consistency of assessment results. The concept of fairness is a consideration of whether there is equity in the assessment process. Fairness is examined so that all participants in an assessment are provided the opportunity to demonstrate what they know and can do. \nUsing Assessment Results Appropriately: Assessment is a critical component of accountability systems, such as those required under Title I-A of the ESEA, and can be the basis of many educational decisions. An assessment can be considered low-stakes or high-stakes, depending on the type of educational decisions made based on its result. For example, a low-stakes assessment may be a formative assessment that measures whether students are on-track to meet proficiency goals. On the other hand, a state high school exit exam is a high-stakes assessment if it determines whether a student will receive a diploma. When the results of assessments are used to make high-stakes decisions that affect students, teachers, districts, and states, it is especially important to have strong evidence of validity, reliability, and fairness. It is therefore important to understand the purpose of educational assessments, and the alignment between the purpose and their use, and to give consideration to the appropriateness of inferences based on assessment results.\nA glossary containing definitions of commonly used assessment and measurement terms is provided at the end of this report.
