All university degrees are formally conferred during the Commencement ceremony on Old Campus. During the ceremony, the dean of Yale College and deans of the graduate and professional schools formally present their approved candidates to the president. The president, in turn, confers the degrees and admits new graduates to each degree’s “rights and responsibilities.” Student marshals from each residential college and school accept symbolic diplomas from the president on behalf of their colleagues. The ceremony lasts approximately 1 hour and 15 minutes.
