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.

Program Rules

  • All auditors are required to register for classes through the CAP office.
  • All auditors must live no more than 50 miles from the Princeton University campus in Princeton, New Jersey.
  • All auditors must be fully vaccinated and provide proof of their COVID-19 vaccination and booster record.
  • All auditors must submit a weekly COVID-19 PCR test to be eligible to attend in-person classes.
  • You may only attend classes that you are enrolled in. Those found attending a class they are not registered for will be suspended from the program for two full semesters beginning immediately.

  • Auditors do not take exams, join labs or precepts, or participate in class. All communication about the program and/or classes must go through the CAP office.

  • Refrain from commenting or asking questions during the class;
  • Refrain from speaking or emailing the professor unless the professor initiates the communication;
  • Arrive to class on-time and refrain from exiting until the class has ended;
  • Turn off cell phones and other electronic devices before entering the classroom;
