Colorado residents aged 55 and older may participate in the Senior Auditors Program. Created in 1973 by the Board of Regents and administered by the Alumni Association, this program allows mature students to keep up to date with the latest research without paying tuition. Tuition is free! The only cost to auditors is an administrative fee to cover IT services and registration assistance. CU-Boulder alumni are entitled to a discount on associated fees. Visit the senior auditor information page for more information or go to the Alumni Association in the Koenig Alumni Center to register.
