Auditing at CU Boulder

The spring 2024 auditor program is now closed to new applicants.

In the meantime, we encourage you to prepare for the upcoming semester.

Find a class to audit
  • Review the restricted courses. Auditors are not eligible to enroll in courses on this list or may need additional department approval as well as the instructor’s approval.
  • Use the CU Boulder Class Search site to see open courses that are not closed or waitlisted.
  • Narrow your search by changing the filters on that page, including Campus, Subject, and Instruction Mode, and update the semester, if needed.
Review auditor costs
  • Spring and Fall terms: Auditors under the age of 55 pay a flat rate of $250.00 per term. Auditors aged 55 and older pay a flat rate of $80 per term (for CU Boulder alumni), and a flat rate of $95 per term (for non-alumni).
