The Senior Auditors Program provides Colorado residents, ages 55 and older, the opportunity to attend classes on the 鶹 campus. Tuition is free and participants pay just an administrative fee to cover registration, application processing and IT support. The program was established in 1973 and is coordinated through the CU-鶹 Alumni Association. Course availability is dependent upon enrollment limits, with tuition-paying students given priority, and on fire code restrictions, which determine the number of students allowed in a room. Grades are not awarded and auditors do not receive credit toward a degree.
