Athletics

  • Division: NCAA Division I (Big Ten)
  • Total athletes: 650 (354 men, 296 women)
  • Sports: 21 varsity (10 men's, 11 women's)
  • Athlete pct: ~1.8% of undergrads

Simulation Notes

  • Category: flagship_public
  • The dramatically lower CS acceptance rate (~7%) vs overall (~42%) is a key characteristic. For the simulation, using the overall rate is appropriate since we model university-level admissions, but the notable field flags this.
  • Strong in-state bias (71% of freshmen are Illinois residents)
  • Very generous financial aid for low-income students ($3,883 net cost for <$30K)

Purdue University

Admissions Overview

  • Overall acceptance rate: 49% (Class of 2028, from 78,745 applicants)
  • Fall 2025 projected: ~43% on ~87K applicants
  • Early Action rate: ~54% vs Regular Decision ~46%

  • Freshman class size: ~11,000

Engineering Selectivity

  • Engineering acceptance rate: 34.7% (SAT 1380-1520, GPA 3.89-4.00)
  • Much more selective than university overall for engineering and CS

Yield

  • Yield rate: 29.1% (Fall 2024, highest since Common App adoption; historically 25-27%)
  • Unexpectedly high yield led to overcrowding, triggering more restrictive future admissions
