The Senior Auditors Program provides Colorado residents, ages 55 and older, the opportunity to attend classes on the 麻豆影院 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-麻豆影院 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.
