ACT retesting occurs when students take the ACT® test multiple times with the goal of improving their scores and postsecondary credentials. In this paper, the author examines preliminary data for the 2022 ACT-tested graduating cohort to better understand the ACT score gains that occur with retesting. The author presents the following six things to…

Students exhibit a variety of test-related behaviors before and during the American College Testing (ACT®) test. Previous ACT research has identified associations between test-related behavior and ACT test performance. For example, test preparation has been shown to be associated with modest ACT Composite score gains on the second ACT testing…

This study employs hierarchal linear modeling to examine whether high school grade inflation occurred between 2010 and 2021, including for students who were tested during the pandemic. The study does so while simultaneously accounting for student and school characteristics. This is the first study, to the current authors' knowledge, that makes use…

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…

We derived an index of high school academic rigor by optimizing the prediction of first-year college GPA based on high school courses taken, grades, and indicators of advanced coursework. Using a large data set (n~108,000) and nominal parameterization of high school course outcomes, the high school academic rigor (HSAR) index capitalizes on…

This study explores inflation in high school grade point average (HSGPA), defined as trend over time in the conditional average of HSGPA, given ACT® Composite score. The time period considered is 2004 to 2011. Using hierarchical linear modeling, the study updates a previous analysis of Woodruff and Ziomek (2004). The study also investigates…

This study examines the differential effects on student subgroups of using the ACT® College Readiness Assessment Composite (ACTC) score and high school grade point average (HSGPA) for making admission decisions. The subgroup characteristics investigated include race/ethnicity, gender, and income. For each student subgroup, we examine the effect of…

Prior research has demonstrated gaps in the academic success of college student subgroups defined by race/ethnicity, income, and gender. We studied trends over time in the success of students in these subgroups in particular first-year college courses: English Composition I, College Algebra, social science courses, and Biology. The study is based…
