Some schools, like the University of Santo Tomas, due to their Spanish heritage, follow Spanish academic attire such as the academic biretta and mozetta. The birreta and mozetta are worn by those from the Graduate School and the Faculty of Medicine and Surgery. Graduates of the Bachelors' programs wear the traditional mortarboard, hood and gown. The professors of the University wear their academic regalia during the Missa de Apertura or the Opening Mass of the Academic Year aside from Solemn Investitures (graduation ceremonies) and other academic activities. The academic colours are unique to this university as these depend on the official color of the faculty or college a student or an academe belongs into.
