This study investigates the benefits of no-stakes educational testing during students' summer vacation as a strategy to mitigate summer learning loss. Fifty-one students in Grades 3-8 from the Every Child Valued (ECV) and Lawrence Community Center (LCC) summer programs in Lawrenceville, NJ, took short, online assessments throughout the summer,…

Several researchers (e.g., Klein, Hamilton, McCaffrey, & Stecher, 2000; Koretz & Barron, 1998; Linn, 2000) have asserted that test-based accountability, a crucial component of U.S. education policy, has resulted in score inflation. This inference has relied on comparisons with performance on other tests such as the National Assessment of…

States are increasingly interested in including measures of student achievement growth, or "value- added," in evaluating teachers. Annual state assessments, however, which are the typical measure of student growth, usually cover only reading and math teachers and only in grades 4-8. These state assessments thus cannot …

States and school districts are exploring alternatives to state tests for measuring teachers' contributions to student learning. One approach applies statistical value-added methods to alternative student assessments such as commercially available tests and end-of course tests. The evidence suggests that these methods can reliably distinguish…

This paper addresses likely error rates for measuring teacher and school performance in the upper elementary grades using value-added models applied to student test score gain data. Using realistic performance measurement system schemes based on hypothesis testing, we develop error rate formulas based on OLS and Empirical Bayes estimators.…

In educational tests, subscores are often generated from a portion of the items in a larger test. Guidelines based on mean squared error are proposed to indicate whether subscores are worth reporting. Alternatives considered are direct reports of subscores, estimates of subscores based on total score, combined estimates based on subscores and…

Reliability and validity are two characteristics that must be considered whenever information about student achievement is collected. However, those characteristics--and the methods for evaluating them--differ in large-scale testing and classroom testing contexts. This article presents the distinctions between reliability and validity in the two…

Research studies have shown that a smaller percentage of students with learning disabilities participate in state assessments than do their peers without learning disabilities. Furthermore, there is almost always a performance gap between these groups of students on these assessments. It is important to evaluate whether a performance gap on a…

One promising application of diagnostic classification models (DCM) is in the area of cognitive diagnostic assessment in education. However, the successful application of DCM in educational testing will likely come with a price--and this price may be in the form of new test development procedures and practices required to yield data that satisfy…

This report describes results from field-testing of POWERSOURCE[C] formative assessment alongside professional development and instructional resources. The researchers at the National Center for Research, on Evaluation, Standards, & Student Testing (CRESST) employed a randomized, controlled design to address the following question: Does the…

ACT is often asked whether student scores on the ACT[R] test can be used to make "norm-referenced" or "standards-referenced" comparisons. Norm-referenced interpretations compare students to one another, while standards-referenced interpretations measure student performance against predefined content standards. This brief shows…

It is essential for all students to be ready for college and career when they graduate from high school. Postsecondary educators expect high school graduates to be prepared academically for success in postsecondary education, which in turn influences success in the work world. Employers continue to call for workers to have the tools needed to…

Extensive education research on the contribution of teachers to student achievement produces two generally accepted results. First, teacher quality varies substantially as measured by the value added to student achievement or future academic attainment or earnings. Second, variables often used to determine entry into the profession and…

Accountability for educational quality is a priority at all levels of education. Low-stakes testing is one way to measure the quality of education that students receive and make inferences about what students know and can do. Aggregate test scores from low-stakes testing programs are suspect, however, to the degree that these scores are influenced…

"America in Black and White: One Nation Indivisible: Race in Modern America," by Stephan and Abigail Thernstrom, has become important in the movement to abolish affirmative action in higher education. Suggests the book seriously misinterprets and misuses evidence to make its case, refuting specific results the book cites related to…
