The Senior Auditors Program provides 蜜糖直播 residents, ages 55 and older, the opportunity to attend classes on the University of 蜜糖直播 Boulder 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 蜜糖直播-Boulder 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.
