Course Numbering Guidelines

Certain catalog numbers are reserved for specific types of courses. This scheme is applicable to courses in Trinity College of Arts & Sciences, Pratt School of Engineering, Nicholas School of the Environment, Sanford School of Public Policy, and The Graduate School.

Catalog numbers are unique to each course and cannot be reused within four years of being active. Catalog numbers that include a suffix cannot be used for a different course. In other words, SUBJECT 101 (lecture-only course) must be the same course as SUBJECT 101S (seminar version of course), 101A (study away version), 101L (lecture and lab version), etc.

To find available catalog numbers, see Help guide: Finding Available Catalog Numbers and consult the charts below.

To request a list of all courses owned by and/or crosslisted with your department (active, inactive, or both), email bulletins@duke.edu. This request may only be made once; after receipt, departments will be responsible for maintaining this list.

Courses offered under the special topics course numbers (e.g., 190, 290L, 390S) are offered on a one-time basis; they are not part of a department’s regularly taught curriculum (permanent courses). Special topics are used by faculty who wish to teach a very specialized subject on a one-time basis, or to try out a new course that may eventually become a permanent course. Special topics may also be used for specialized courses taught by visiting faculty.

Because the particular topic will be different each time the course is taught, departments must apply for the appropriate curricular codes using the Special Topics form on the Course Request System each time the course is offered. Even if a particular topic has been offered in a previous semester, the curriculum codes will not carry over on DukeHub unless the Special Topic Request form has been submitted for the current semester. The topic title and any crosslisted offerings in the request must match the primary department’s submission in CLSS; requests that do not match exactly will not be reviewed until any issues are rectified.

Only approved special topics courses and curriculum codes may be advertised by a department. Departments should confirm that their special topic titles and codes have been approved and applied to the schedule of classes before promoting them on a departmental website or social media account.

See Trinity’s guidelines for Course Requests for additional information regarding special topics courses.

Course Request System

Requests for all courses within Trinity College of Arts & Sciences, Pratt School of Engineering, and The Graduate School are submitted to the Office of Curriculum and Course Development and reviewed by the Faculty Committee on Courses, a standing committee of the Arts & Sciences Council.

Departments must use the Course Request System to add, drop, or revise regular courses and to request coding for Special Topics courses. See the Guide to the Duke University Course Request System for help submitting a request.

Once a request has been reviewed by the committee, the status will read either Submitted to Registrar (Approved) or Courses Committee – Declined. Users should look at the bottom of the request in the Courses Committee Review section to see if there are any committee comments. Approved curriculum codes will appear at the bottom of any request; if codes are denied, the decision will be explained in the committee’s comments.
