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 a master of business administration 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.
