Community Auditing

Princeton University's Community Auditing Program (CAP) enables members of the community, high school graduates ages 18 and above, to audit, or sit in on, University lectures on a non-credit basis for $200 per course unless otherwise noted. Auditors must live in New Jersey or be within a 50 mile radius of Princeton University. On average, 150-175 classes are available each semester for auditing. No credit or certification is given for CAP classes. However, certified teachers currently working in New Jersey and Au Pairs may obtain written verification for classes they have audited.
