This report describes the process of developing and validating the enhanced ACT. The report describes the changes made to the test content and the processes by which these design decisions were implemented. The authors describe how they shared the overall scope of the enhancements, including the initial blueprints, with external expert panels,…

As testing programs transition from paper to online testing, they must study mode comparability to support the exchangeability of scores from different testing modes. To that end, a series of three mode comparability studies was conducted during the 2019-2020 academic year with examinees randomly assigned to take the ACT college admissions exam on…

For this project, ACT developed math and science items that attempted to represent unique aspects of cultures, raise awareness of social justice issues, promote cultural learning, be authentic and relatable, be comprehensible, and represent people in positive, nonstereotypical ways. Creating culturally relevant items was a new challenge for ACT…

Starting in April 2025, ACT will introduce enhanced forms of the ACT® test for national online testing, with a full rollout to all paper and online test takers in national, state and district, and international test administrations by Spring 2026. ACT introduced major updates by changing the test lengths and testing times, providing more time per…

This report summarizes some of the evidence supporting interpretations of scores from the enhanced ACT, focusing on reliability, concurrent validity, predictive validity, and score comparability. The authors argue that the evidence presented in this report supports the interpretation of scores from the enhanced ACT as measures of high school…

The present study examined the relationship between working memory capacity (WMC) and comprehension on a multiple text assessment from the ACT test for college preparedness in which texts are available during question answering. Specifically, it was of interest whether differences in relations would be seen across different question types. Only…

Speeded tests set time limits so that few examinees can reach all items, and power tests allow most test-takers sufficient time to attempt all items. Educational achievement tests are sometimes described as "timed power tests" because the amount of time provided is intended to allow nearly all students to complete the test, yet this…

This meta-analysis examined the validity of an alternative to traditional assessments called the Wonderlic which is a brief measure of general mental ability. Our results showed significant, positive correlations between Wonderlic scores and academic performance in general ([r-bar] = 0.26), between Wonderlic scores and undergraduate GPA in…

This mixed-methods study explored American College Test (ACT) composite scores and Tennessee Value-Added Assessment System (TVAAS) growth scores in connection with a student's race, socioeconomic status, and gender as well as perceived factors that promote or inhibit success on the ACT. Quantitative data were collected from existing TVAAS data for…

To meet graduation requirements, public school students in Florida must participate in and pass any statewide, standardized assessments required for a standard diploma or earn identified concordant scores or comparative scores, as applicable, for the cohort year in which they entered in ninth grade (M-DCPS, 2024). One of the statewide assessments…

The American College Test (ACT) serves as the most utilized college admissions test in the United States. With disparities existing in the scores of Black males on the ACT exam compared to their peers, it is imperative to explore how these students are perceiving and experiencing the ACT. This study explored how Black male students experience the…

Colleges and universities have become increasingly concerned that requiring standardized test scores for admission is an impediment to campus diversity, and these objections have grown with the recent focus on societal inequities. In addition, the pandemic led to the cancellation of test administrations, which, in turn, caused many institutions to…

This ex-post facto quantitative study examined how a comprehensive STEM education program impacts high school students' ACT math and science scores as well as their attitudes toward STEM. Using data from one STEM-designated school, the researcher examined ACT math, science, and STEM results for students who took the ACT in the Spring of 2024,…

Despite extensive research on assessing collocational knowledge, valid measures of academic collocations remain elusive. With the present study, we employ an argument-based approach to validate two Academic Collocation Tests (ACTs) that assess the ability to recognize and produce academic collocations (i.e., two-word units such as "key…

As access to higher education increases, it is important to monitor students with special needs to facilitate the provision of appropriate resources and support. Although metrics such as the "reading readiness" ACT (formerly American College Testing) of provide insight into how many students may need such resources, they do not specify…
