Community Auditors at CU Boulder

We are delighted you are interested in joining the CU Boulder community as an auditor. Auditing allows you the opportunity to attend university classes for no academic credit. Listen to lectures given by our world-class faculty and get more involved with the campus.

Community members age 18-54, who are not registered students but wish to listen in on regularly scheduled lectures, are eligible to audit courses during the fall, spring, and summer semesters.

Senior Auditors

If you are a Colorado resident age 55 or over, the CU Boulder Alumni Association offers a special Senior Auditors Program. Contact the CU Boulder Alumni Association via phone at 303-492-8484 or via email at for more information.
