Returning students (those not enrolled during the immediately preceding semester, excluding summer session) should first secure written permission from the college where they were last enrolled before getting their Admission Slip (UP Form 4) from the Office of the University Registrar. They should then proceed to the University Health Service for a physical and medical examination before registering in their respective colleges.

Former students who have attended another institution since attending the University must qualify on the same basis as new transfer students.
