Answer:
Degrees are conferred upon all candidates during the Commencement ceremony, but students do not receive individual diplomas. At the Old Campus ceremony, symbolic diplomas are presented to student marshals, who accept them on behalf of fellow degree candidates. The official Latin diplomas are distributed at a separate ceremony in each residential college and professional school. Diplomas for the Graduate School are presented in Woolsey Hall and Horchow Hall.
Diploma ceremonies in some colleges and schools may last until 1:45 p.m., so lunch could be later than usual for many guests. A packed snack might be prudent, especially for younger or older family members.
