Courses numbered 8000-9999, taught by members of the graduate faculty, are advanced graduate courses and seminars which provide educational experiences at the highest level in a graduate student’s program of study. Courses numbered 6000-6999 are fundamental knowledge courses; those numbered 7000-7999, except master’s research (7000) and thesis (7300), are technique and professional courses. Courses numbered 6000-7999 are normally taken early in the graduate student’s program of study. Joint undergraduate/graduate courses, numbered 4000-4999/6000-6999 and 5000-5999/ 7000-7999, in which undergraduate and graduate students are simultaneously enrolled are not normally used to provide the core requirements of a graduate degree program. Such courses may be used as electives and as service courses taken in other departments.
