​No one is permitted to attend a class for which he or she has not been properly registered. Credit is accumulated on the basis of quarter hours. The unit of credit is one quarter hour granted for 45 minutes of classroom work a week. The normal class extends over a ten-week period (or an accelerated five-week period in the summer). All courses carry four quarter hours of credit (2 2/3 semester hours), unless otherwise noted.

Graduate music students enrolled for six or more quarter hours of credit are considered full-time. Those registered for less than 6 quarter hours of credit are considered less than half-time.

Graduate courses are numbered as 400 level courses. Graduate students must enroll for 400 level courses.
