The full academic dress is worn during solemn investiture ceremonies and special occasions, such as, Misa de Apertura, or the Mass of the Holy Spirit, and on installation of a new rector.
Biretta - Birettas are used by doctorate and master's degree holders. The black birettas used by the doctors have a colored tuft or fringes corresponding to the college color or field of study. The black birettas used by the master's degree graduates lack fringes. The Ecclesiastical Faculties use a four or a three horned biretta that bears a colored pom. The Faculty of Medicine and Surgery uses an octagonal biretta with yellow fringes.[3]
Mortarboard - Bachelor's degree holders use a black square mortarboard with colored tassels that correspond to their college color.[3][4]
Mozzettas are used by the doctorate and master's degree holders. The color depends on the academic field. The graduates of business and management, in particular, uses yellow mozzetta.[3]
Hoods are used by the bachelor's degree graduates. The color of the hood depends on the academic field.[3][4] The Faculty of Pharmacy's academic color is purple, but a second color is added to the hood of its 2 programs. Light blue is added to the B.S. Biochemistry graduates, while yellow is added to the B.S. Medical Technology graduates.
Each college in the university has a designated color. Some colleges follow the color system used in Spain. These are the "Faculties" (with the exemption of the Faculty of Engineering) and the College of Science. The Ecclesiastical faculties adapt the color system used in Pontifical universities. Graduates of doctor and master degrees use the color of the college associated with their academic field instead of the college colors of the Graduate School, which are gold, white, and blue. Below is a list of the college colors used of the university.[7]
