About 4,500 graduating students will take part in one of eight official commencement ceremonies scheduled at UCSB over eight days starting June 7 and concluding June 14. The campus’s commencement exercises attract an estimated 40,000 visitors to the Santa Barbara area each year.

As is traditional at UCSB, the ceremonies are organized by college, level of degree and field of study so that each student can be individually recognized. Chancellor Henry Yang will shake the hand of each graduate from the College of Creative Studies, the College of Engineering, the College of Letters and Science, the Donald Bren School of Environmental Science and Management and the Graduate Division.

The College of Creative Studies will lead off with its ceremony at 11 a.m. Sunday in Campbell Hall. The Donald Bren School of Environmental Science and Management will conduct its ceremony at 10 a.m. June 12 in the Bren Hall Courtyard.
