The Iowa Regents Admission Index (RAI) is a formula used by Iowa’s three public universities—University of Iowa, Iowa State University, and University of Northern Iowa—to help determine admission eligibility for first-time freshmen. The RAI considers a student’s grades, class rank, standardized test scores, and rigor of high school coursework.
The RAI combines several factors:
Grade Point Average (GPA) – Weighted by the rigor of courses (core subjects like English, Math, Science, and Social Studies).
Class Rank – Where you stand compared to your high school classmates.
Standardized Test Scores – ACT or SAT results.
Each factor is assigned a point value, and the total RAI score helps universities evaluate eligibility for admission.
(3 x ACT composite score)
+ (30 x Cumulative GPA)
+ (5 x Number of years of RAI-approved high school courses completed in the core subject areas)
= RAI score (score of 245 qualifies for automatic admission as a freshman)
RAI is used for admission decisions at Iowa’s public universities.
It can also affect scholarship eligibility.
Students with a RAI score meeting or exceeding the university minimum are considered automatically eligible for admission.
Take challenging courses in core subjects to maximize your GPA component.
Prepare for the ACT or SAT to earn higher points for standardized testing.
Know your class rank and work with your counselor to understand how it factors into your RAI score.
HCHS counselors can provide your estimated RAI score and explain how your courses and test scores impact it.
