An important thing to consider when looking at Iowa Public Universities (Iowa, Iowa State and Northern Iowa) is the Regent Admissions Index or RAI. This is a formula used by these universities to grant admission. This is basically a combination of ACT or SAT score, Class rank and GPA of core courses taken. The best information available is on the High School website. Feel free to contact your HS counselor if you have any questions. Markhovey@ccaschools.org or GrantElsbern@ccaschools.org.
