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 aged 18 and older, 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.

Please note that the University’s primary commitment is to degree-seeking and credit-seeking students. Auditors’ course requests will be processed after these groups have registered.

Senior Auditors and Community Auditors Program Updates

The Senior Auditors program, formerly offered by the CU Boulder Alumni Association, along with the Community Auditors program previously offered by Continuing Education, have been incorporated into the new Continuing Education Auditors program.

The Spring 2024 application will be available on January 2, 2024. Please refer to the Auditors enrollment page for information on how to apply, register for courses, and current auditor restrictions.

The Instructor Permission form may be printed out and returned in person or submitted online. Submit your Instructor Permission form early, before the course enrollment period starts, to avoid processing delays.


Now that you’ve selected your favorite Continuing Education courses, email or print the information, including class number, to more easily search Buff Portal and enroll. Still have questions? Contact an advisor.
