This study conducted in collaboration with a postsecondary institution highlights results from a concurrent validity study of administering ACT® section tests to their entering freshmen who previously took the ACT test in high school. Students' ACT scores obtained from section retesting were found to be as predictive of first-term grade point average (GPA) as scores obtained via traditional ACT testing. Additionally, ACT Superscores that were computed across test administrations that included single-subject section test events were found to be predictive of first-term GPA, alone and in combination with high school GPA. Moreover, the strength of this relationship did not significantly differ from that based on students' most recent ACT Composite scores.
