Part 2 of 2 - Diploma Distribution. The Processional and Main Program ceremony is in Part 1. The 144th Annual Commencement for Oregon State University was held on June 15, 2013. The Class of 2013 stands in their last line at OSU, when they (finally!) receive their diplomas. Oregon State is fairly unique in that each graduate who attends Commencement walks away with their own diploma - not a cover, but the actual diploma with their name on it.
