Enter your unweighted GPA, SAT or ACT score, and class rank to calculate your Academic Index (AI) — the formula Ivy League coaches use to evaluate recruited athletes. You'll see your AI score, a CGS (Converted Grade Score), a converted test score, and an interpretation of where you stand on Ivy League recruiting standards.

The Academic Index is a numeric score, typically ranging from about 60 to 240, that Ivy League schools use to evaluate the academic qualifications of recruited athletes. It combines a student's GPA/class rank and standardized test scores into a single number so coaches and admissions offices can quickly assess academic eligibility.
The AI is calculated by adding a Converted Grade Score (CGS), which is derived from your GPA or class rank, to a Converted Test Score derived from your SAT or ACT. Each component is scaled to produce a final AI score. Roughly two-thirds of the index is weighted toward test scores and one-third toward grades/rank, depending on the specific formula version used.
Ivy League athletic programs require that a team's average Academic Index meets or exceeds a school-specific minimum (typically around 176). Individual recruited athletes generally need an AI of at least 171, though this varies by sport and school. Athletes with AI scores below 167 are rarely admitted as recruited athletes.
Yes. If your school does not report class rank, Ivy League programs typically substitute your unweighted GPA to compute the Converted Grade Score. This calculator uses your GPA directly in that scenario, which is standard practice among Ivy League athletic departments.
Yes, all Ivy League athletic programs — from football and basketball to track & field and rowing — must comply with Academic Index requirements. Each team's average AI is monitored, and coaches cannot recruit athletes whose AI is significantly below the band average without jeopardizing the team's eligibility.
The ACT composite score is converted to an equivalent SAT-like scale using an official concordance table, and then that converted score is used to calculate the Converted Test Score component of the AI. This calculator applies that standard ACT-to-AI conversion automatically when you select ACT.
No. A strong Academic Index is a necessary threshold but not sufficient on its own. Ivy League admissions remain holistic — essays, recommendations, extracurriculars, and the overall application still matter enormously. The AI determines whether a coach can actively support your application, not whether you will be admitted.
Scores above 220 are considered excellent and reflect near-perfect GPAs and test scores. Scores in the 176–219 range are competitive for Ivy League athletic recruitment. Scores between 167–175 are borderline, and scores below 167 make Ivy League athletic recruitment very unlikely.
