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).

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…

The validity of prediction equations based on American College Testing (ACT) Program test scores and high school grades is investigated. Presented are separate results for prediction equations based on ACT scores only, on high school grades only, and on both kinds of prediction jointly. Also included is a discussion of the relationship between…
