Developmental education courses have been designed to support underprepared students, as they attempt to bridge the gap in academic knowledge among students who enter postsecondary education underprepared for college-level coursework. The effectiveness of these programs, however, particularly in terms of promoting degree attainment, remains an…

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…

In this study, I examined several ecological factors at play when students make use of test preparation. I first looked at students' usage of test preparation and followed that with an examination of the relationship between family income and test preparation use. Finally, I examined familial support in preparing for admissions exams. Many…

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…

The COVID-19 pandemic caused widespread disruptions to the educational system in Nebraska and across the world. At the onset of the pandemic in March 2020, schools in Nebraska were forced to replace on-site instruction with virtual instruction. During the 2020-2021 academic year, many students learned online or under hybrid learning formats.…

Employment status in high school has been shown to have a negative relationship with measures of academic achievement which some researchers have attributed to student characteristics such as demographics and socioeconomic status. The current study investigated differences in the demographic and socioeconomic characteristics of "working…

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…

Professional standards for educational testing recommend that both the overall standard error of measurement and the conditional standard error of measurement (CSEM) be computed on the score scale used to report scores to examinees. Several methods have been developed to compute scale score CSEMs. This paper compares three methods, based on…

As pushes for increased accountability in higher education continue, postsecondary institutions are interested in identifying early on students who are at-risk of leaving their institution. With this in mind, this study sought to identify incoming first-year student information (such as that available on the ACT student record) that postsecondary…

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…

It was estimated that 92% of 2004 high school graduates in the United States planned to continue their education after high school. Why might students not plan to go to college? Common concerns include inadequate academic preparation, a lack of understanding of the enrollment process, and the perceived economic benefit of college attendance. This…

This study examined the effects of differential grading in science, technology, engineering, and mathematics (STEM) and non-STEM fields over eight consecutive semesters. Using data from 62,122 students at 26 four-year postsecondary institutions, students were subdivided by institutional admission selectivity levels, gender, and student major…
