A student who wishes to qualify for the doctorate should formulate a program of study in consultation with his or her graduate adviser or committee. The course and research requirements for the doctoral degree in each subject are determined by the faculties concerned, although all programs are subject to review by the dean of the Graduate School-New Brunswick. The minimum total requirement of nonresearch courses varies by program, although it rarely exceeds 48 credits. The student must offer a minimum of 24 credits in research toward the degree. The minimum combined total credit requirement is 72 credits. No more than 12 credits of advanced undergraduate courses (300 or 400 series with added G prefixes) may be offered toward the degree. No more than 50 percent of a student's formal coursework may be taken in professional school courses. In most programs, a student is able to complete coursework in two years of full-time study. Courses taken to satisfy the requirements for a master's degree may, with program approval, be counted toward the doctorate. The time of transition from coursework to guided or independent research is determined by the faculty of the student's program. The entire doctoral program should be completed no later than seven years after the student first registers in the Graduate School-New Brunswick.
