Regent Admission Index (RAI) Score
The Regent Admission Index (RAI) combines four factors that strongly predict success at Iowa's regent universities: ACT score, high school percentile rank, high school grade-point average (GPA), and the number of high school courses completed in core subject areas. A student's RAI score is used for admission to the College of Liberal Arts and Sciences and is one of the criteria used for admission to the College of Engineering. It also is used in awarding some University of Iowa scholarships.

How to calculate your RAI:

2 x ACT Composite Score (or the SAT Equivalent)

1 x High School Percentile Rank

5 x Number of Core Courses Completed

Which core courses count in the RAI?
Any college-prep course in English, mathematics, science, social studies, and foreign language can be used in calculating a student’s RAI score. To be considered for admission, students must have taken (or plan to take) at least 15 college-prep courses (full-year) including the following:

• 4 years of English
• 3 years of mathematics, including Algebra I, Algebra II, and geometry (Engineering requires a 4^th year of mathematics)
• 3 years of social studies (Engineering requires only 2 years)
• 2 years of the same foreign language
• 3 years of science, including one year from two of theses areas: biology, chemistry, and physics; and a third year from any science area.

All other courses in these areas (above and beyond those required for admission), can be used in calculating the RAI. High school counselors can help students and parents determine which courses qualify as “college-prep” or students can call the Office of Admissions.

How to calculate your percentile rank
To calculate your percentile rank, subtract your position in your high school class from the number of students in that class, divide the resulting number by the number of students in your class, and multiply by 100. The Online RAI Calculator can compute this for you.

If your high school does not rank, you will not be able to calculate an RAI score, so we will base our admission decision on a holistic review of your application materials.
