In recent ACT mode comparability studies, students testing on laptop or desktop computers earned slightly higher scores on average than students who tested on paper, especially on the ACT® reading and English tests (Li et al., 2017). Equating procedures adjust for such "mode effects" to make ACT scores comparable regardless of testing…

As part of ACT's Holistic Framework, ACT researchers developed a Behavioral Skills Framework that can be used to assess behavior in education and work settings. By utilizing specific statements of effective behaviors, known as performance level descriptors (PLDs) (e.g., communicating well in group tasks), the Behavioral Skills Framework is…

The percentage of students retaking college admissions tests is rising (Harmston & Crouse, 2016). Researchers and college admissions offices currently use a variety of methods for summarizing these multiple scores. Testing companies, interested in validity evidence like correlations with college first-year grade-point averages (FYGPA), often…

This study is an extension of two previous studies that provided profiles of persisting STEM majors overall (regardless of academic performance) and persisting STEM majors who earned semester GPAs of 3.0 or higher (Westrick, 2016, 2017). Using data from 25 four-year institutions, this study compared the mean ACT assessment scores, HSGPAs, and ACT…

In preparation for online administration of the ACT® test, ACT conducted studies to examine the comparability of scores between online and paper administrations, including a timing study in fall 2013, a mode comparability study in spring 2014, and a second mode comparability study in spring 2015. This report presents major findings from these…

Building upon the research findings in an earlier ACT Research Report (Westrick, 2016), this study used data from 119,131 students at 26 four-year institutions to make comparisons between STEM majors earning semester GPAs of 3.0 or higher and their STEM peers earning semester GPAs less than 3.0. The results indicate that the higher-performing…

ACT reporting categories and ACT Readiness Ranges are new features added to the ACT score reports starting in fall 2016. For each reporting category, the number correct score, the maximum points possible, the percent correct, and the ACT Readiness Range, along with an indicator of whether the reporting category score falls within the Readiness…

Using date from 120,612 students at 26 four-year institutions, this report provides a description of STEM majors entering four-year postsecondary institutions and those who persist through four years of study. The results indicate that persisting STEM majors enter college with very high levels of pre-college academic achievement as measured by the…

Research has shown that science, technology, engineering, and mathematics (STEM) majors who are more academically prepared--especially in terms of their mathematics and science test scores--are more likely to be successful across a variety of outcomes: cumulative grade point average (GPA), persistence in a STEM major, and ultimately earning a STEM…

This study examined the contributions of students' noncognitive characteristics toward explaining performance on the ACT® test, over and above traditional predictors such as high school grade point average (HSGPA), coursework taken, and school characteristics. The sample consisted of 6,440 high school seniors from 4,541 schools who took the ACT in…

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…

Education officials and journalists frequently track changes over time in the average ACT® College Readiness Assessment Composite scores and ACT College Readiness Benchmark attainment rates of individual high schools. Using standard statistical methods, I examined how often changes in these statistics are unambiguously positive or negative, rather…

The ACT College Readiness Benchmarks are the ACT® College Readiness Assessment scores associated with a 50% chance of earning a B or higher grade in typical first-year credit-bearing college courses. The Benchmarks also correspond to an approximate 75% chance of earning a C or higher grade in these courses. There are four Benchmarks, corresponding…

In recent years, state policymakers have increased high school course requirements--particularly in mathematics and science. This research examines whether stricter requirements have been effective at improving student outcomes. Student-level evidence from a state's recent reform suggests that higher requirements had little effect on trends in…

This "College Choice Report" is part of a report series that focuses on the ACT-tested high school graduating class of 2013. The focus of this year's "College Choice Report" is students' selection of a college major or program of study among the ACT-tested high school graduating class of 2013. This year's report is provided in…
