NOTE: Estimates are based on all students who took the ACT assessment during their sophomore, junior, or senior year, and who graduated from high school in the spring of the respective year shown. If a student tested more than once, only his/her most recent test record was used. Test-takers were asked to self-identify a single racial/ethnic group. Race categories exclude persons of Hispanic ethnicity.
