USAC's programs offers additional services to the campus and surrounding communities. For example, each year approximately 40,000 students, faculty and staff attend programs of the Campus Events Commission, including a low-cost film program, a speakers program which presents leading figures from a wide range of disciplines, and performances by dozens of entertainers. Two to three thousand UCLA undergraduates participate annually in the more than twenty voluntary outreach programs run by the Community Service Commission. A large corps of undergraduate volunteers also participate in programs run by the Student Welfare Commission, such as AIDS Awareness, Substance Abuse Awareness, Blood Drives and CPR/First Aid Training.
