Auditor Restrictions

The following course instruction modes are available to auditors:

  • Boulder Main Campus: All instruction modes are available
  • Continuing Education Campus: CE Online Credit term-based classes and CE Evening Credit classes (in-person, hybrid remote/online, hybrid in-person/online-remote)

Current degree students receive enrollment priority. Auditors will only be added to open courses. Auditors will not be enrolled in closed or waitlisted courses regardless of instructor permission. Course enrollment numbers can change rapidly at the beginning of the term; your requested classes will need to be open at the time of auditor enrollment. Auditors are limited to 21 credit hours’ worth of course enrollment each term.

An auditor may not switch from being an auditor to enrolling in a course for credit within the same semester. Community members interested in learning more about taking courses for credit can visit the ACCESS program page or contact an academic advisor.

Participants in the Auditors Program must be over the age of 18 and not be registered as either a degree-seeking or nondegree student at CU Boulder. Auditors are not considered students and do not receive the same privileges as enrolled or nondegree students. Registered auditors receive class instruction, access to the online learning management system, and library privileges only. Acceptance to the University of Colorado Boulder as an auditor does not guarantee eligibility for regular degree or nondegree status.

Admitted students, either enrolled or suspended, may not attend courses as an auditor. If an admitted degree student is interested in participating in a class without receiving credit, the student must enroll in the course for no credit and select that as their grading option. Courses taken for no credit are assessed the same tuition rate as courses taken for credit.

The following classes are not available to auditors:

  • Any class that is at its enrollment capacity (closed) or has a waitlist
  • Any course with a travel component
  • LAB and REC (recitation) sections of classes, including MLS (main lab section) standalone classes
