Community Auditing Program

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 $175 per course unless otherwise noted. On average, 200 classes are available each semester for auditing. No credit or certification is given for CAP classes. However, certified teachers currently working in New Jersey may obtain written certification for classes they have audited.

Program Requirements

  • All auditors are required to register for classes through the CAP office. If you are not enrolled in a class, you may not attend that class. Those on wait lists may not attend the class until they are notified a seat has become available.
  • Those found attending a class they are not registered for will be suspended from the program for two full semesters beginning immediately. If you are a repeat offender of this rule, you will be prohibited from future participation in the Community Auditing Program.
  • Auditors are to attend only the lectures for which they are registered, and may not attend precepts, seminars, field trips, or language and science labs.
  • All communication about the program and/or classes must go through the CAP office. Auditors are NOT permitted to contact professors or departments directly. Those ignoring this policy will be suspended from the program for two full semesters beginning immediately.
  • The primary mission of the University is to serve as a preeminent educational and research institution for fully enrolled students. Thus, auditors are to be as unobtrusive as possible in the classroom and considerate of the fully enrolled students by doing the following:
  1. Refrain from commenting or asking questions during the class;
  2. Refrain from speaking or emailing the professor unless the professor initiates the communication;
  3. Refrain from entering or exiting the classroom or lecture hall once the class has started;
  4. Sit only in the back rows of the classroom or lecture hall; University students have first priority for seating.
  5. Refrain from purchasing books at the local bookstores or any bookseller until after the second week of classes has ended;
  6. Turn off cell phones and other electronic devices before entering the classroom.

Those auditors who do not adhere to the above requirements will be asked to leave the program.
