The designation of graduate students as full or part time is necessary for the regulations governing tuition charges, student fees, statistical records, time limits for degrees, residence requirements, and any other issues affected by such status. A graduate student registered for 9 or more credits has full-time status; a student registered for fewer than 9 credits has part-time status; 6 credits is half-time status. The School of Business-Camden requires an M.B.A. student to be registered for 12 or more credits to have full-time status. In addition to regular coursework, the following also are included in the calculation of credits: research courses, regular courses taken not-for-credit, and graduate and teaching assistantships (usually 6 credits each). Graduate and teaching assistants must remain in good standing in their own programs. In addition to their half-time academic appointments, assistants are required to register for a minimum of 6 credits of coursework or research, thereby qualifying for full-time status.
