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 who do not live in New Jersey must live within a 50 mile commuting distance of Princeton University.
  • 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. If you are a repeat offender of this rule, you will be prohibited from future participation in the Community Auditing Program.
  • Those on a wait list for a class, may not attend the class until they are notified a seat has become available, and have registered for the class.
  • Auditors may register for up to 3 University classes per semester. Auditor Only classes are not counted as University classes.
  • Auditors do not take exams or participate in class. They may not attend precepts, seminars, field trips, language labs or science labs.
  • Auditors may not bring guests to class.
  • 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. Turn off cell phones and other electronic devices before entering the classroom.
  6. Refrain from inviting professors out to coffee or lunch.

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

If you have a question for a professor, kindly forward it to and we will contact the professor on your behalf.
