Students who have been awarded a master of philosophy   degree may proceed directly toward the Ph.D. if they are admitted into the   program and continue their registration. On the other hand, these students   may elect to allow their registration to lapse for as long as four years   without paying a restoral fee. To activate a lapsed registration, the   student must submit an application for readmission to the Graduate   School-New Brunswick at any time within the four-year window. With   the program director's endorsement, readmission is automatic within   the four years. (See Readmission in the Academic Policies and Procedures   chapter.) After more than four years, holders of the master of philosophy   degree may apply for readmission, but their graduate director may require   them to take a refresher course or meet other requirements for readmission.
