Debilitating test anxiety is a general threat to validity if it biases assessment scores. Moreover, if bias differs between demographic groups, anxiety also raises concerns about test fairness. This study applied structural equation modeling to investigate possible measurement bias due to anxiety on the ACT® assessment and relationships among…

One of the major claims of the report of University of California's Task Force on Standardized Testing is that SAT and ACT scores are superior to high-school grades in predicting how students will perform at UC. This finding has been widely reported in the news media and cited in several editorials favoring UC's continued use of SAT/ACT scores in…

On May 21, 2020, the University of California (UC) Board of Regents unanimously approved the suspension of the standardized test requirement (ACT/SAT) for all California freshman applicants until fall 2024. UC plans to create a new test that better aligns with the content the University expects students to have mastered for college readiness.…

The Every Student Succeeds Act requires that English Learners (ELs) are included in annual state testing (grades 3-8 and once in high school) and included in each state's accountability system disaggregated by subgroup to ensure that they receive the support they need to learn English, participate fully in their education experience, and graduate…

The number of applications to postsecondary institutions continues to increase year over year, and in most cases, the number of applications exceeds the number of students admitted. The use of standardized tests continues to grow to help in these admissions decisions. Due to both high usage rates and the changing demographics of our nation's…

This study compares two methods of defining groups for the detection of differential item functioning (DIF): (a) pairwise comparisons and (b) composite group comparisons. We aim to emphasize and empirically support the notion that the choice of pairwise versus composite group definitions in DIF is a reflection of how one defines fairness in DIF…

For more than seventy-five years, standardized tests have been considered a vital tool for gauging students' readiness for college. However, few people--including students, parents, teachers, and policy makers--understand how tests like the SAT or ACT are used in admissions decisions. Once touted as the best way to compare students from diverse…

Proficiency with written communication (WC) is critical for success in college and careers. As a result, institutions face a growing challenge to accurately evaluate their students' writing skills to obtain data that can support demands of accreditation, accountability, or curricular improvement. Many current standardized measures, however, lack…

The test-optional movement in the United States emerged largely in response to criticism of standardized admissions tests as inadequate and potentially biased measures of postsecondary promise. Although anecdotal reports suggest that test-optional policies have improved campus diversity, empirical research has not yet confirmed this claim.…

In this research report, we review commonly held beliefs about test-optional policies and practices. Focusing solely on empirical evidence, we highlight research findings that directly address the state intentions and actual outcomes of such practices. Throughout the paper, we raise concerns with test-optional policies as they pertain both to…

In this technical brief, the authors summarize empirical evidence from their full report comparing the stated intentions and actual outcomes of test-optional practices. An overview of five commonly stated assertions of test-optional practices along with empirical evidence that contradicts these assertions is provided in this brief. [For the full…

Most American colleges and universities require standardized entrance exams when making admissions decisions. Scores on these exams help determine if, when and where students will be allowed to pursue higher education. These scores are also used to determine eligibility for merit based financial aid. This testing persists even though half of the…

Views on testing--its purpose and uses and how its data are analyzed--are related to one's perspective on test takers. Test takers can be viewed as learners, examinees, or contestants. I briefly discuss the perspective of test takers as learners. I maintain that much of psychometrics views test takers as examinees. I discuss test takers as a…

This manual contains information about the American College Test (ACT) Plan® program. The principal focus of this manual is to document the Plan program's technical adequacy in light of its intended purposes. This manual supersedes the 2011 edition. The content of this manual responds to requirements of the testing industry as established in the…

Data from college admissions tests can provide a valuable measure of student achievement, but the non-representativeness of test-takers is an important concern. We examine selectivity bias in both state-level and school-level SAT and ACT averages. The degree of selectivity may differ importantly across and within schools, and across and within…
