100-299 Lower-Division Courses: Open to first-year students and sophomores unless otherwise restricted.

300-499 Upper-Division Courses: Generally open to juniors and seniors unless otherwise specified.* Also open to graduate students, and may be considered part of a graduate program provided they are not specific requirements in preparation for graduate study.

500-599 Graduate Courses: Normally open to graduate students only. If, during the last semester of the senior year, a candidate for a baccalaureate degree finds it possible to complete all degree requirements with a registration of fewer than 16 semester hours of undergraduate credit, registration for graduate credit is permissible. However, the total registration for undergraduate requirements and elective graduate credit shall not exceed 16 semester hours during the semester. A memorandum stating that all baccalaureate requirements are being met during the current semester must be signed by the appropriate department chair or school dean and presented to the dean of graduate studies at the time of such registration. This registration does not apply toward a higher degree unless it is later approved by the student’s advisor and/or advisory committee.

900-999 Continuing Education Courses: Courses reserved for all continuing education students.

*     Note: Lower-division students may enroll in upper-division courses if prerequisites have been met.
