Class and Classroom Scheduling

The Office of the University Registrar works with school and departmental staff in the following schools to create and schedule courses and classrooms each term:  Graduate School, Nicholas School of the Environment, Pratt School of Engineering, Sanford School of Public Policy, and Trinity College of Arts & Sciences. 

Departments use the Departmental Schedule Validator (DSV) application to submit scheduling requests to the Office of the University Registrar (OUR). The OUR then updates the data in DukeHub. The DSV tracks scheduling requests and checks for compliance with the Course Scheduling Policy. The DSV is accessible via the Department Center in DukeHub.

DSV Access

To gain access to the DSV:

  1. Submit a SISS Access Request form to gain access to SISS systems including DukeHub and the DSV. Check DSV under the Data Access section.
    https://sissoffice.duke.edu/requestforms/accessreq.html
  2. Attend DSV Training. Complete the DSV Training Form to register for a class.

Helpful Tips and Important Reminders:
  • All additions, deletions, and revisions to your schedule must be submitted in the DSV.
  • Schedules must be validated prior to submission.
  • Classes are set up on the schedule according to how the courses are set up in the course catalog. This includes (but is not limited to): class permissions, prerequisites, REG codes, credits, and permanent crosslists.
  • The DSV pulls permanently crosslisted courses from the catalog, which are required to be scheduled. However, there is also the option to add one-time crosslists. IMPORTANT: Communicate with the department that you intend to crosslist courses with prior to adding the course to your schedule. (Be sure to discuss what section number should be used).
  • Although you can create several schedules, the primary schedule is the official schedule and the only one you can submit. You cannot change another schedule to be primary after it is submitted.
  • If you want to secure a room in the Link or ICC, please request the corresponding room characteristic and provide explanation for need in the NOTES section.

Undergraduate and Graduate Course Schedule, Courses Numbered 1-699
(Revised January 2012, Effective Fall 2012)

Time Periods: Monday through Friday (note the "nesting" of 50-minute courses within 75-minute courses)
Period 75 Minute Classes 50 Minute Classes
1 8:30 - 9:45 8:45 - 9:35
2 10:05 - 11:20 10:20 - 11:11:10
3 11:45 - 1:00 12:00 - 12:50
4 1:25 - 2:40 1:40 - 2:30
5 3:05 - 4:20 3:20 - 4:10
6 4:40 - 5:55 4:55 - 5:45
7 6:15 - 7:30 6:30 - 7:20
8 7:30 - ... 7:30 - ...
  • All classes, regardless of length, must begin at the starting times above. In other words, all classes meeting in 75 minute sessions must start at the times in the first column and those in 50 minute sessions must start at the times in the second column. In addition, classes not meeting for either 75 minute or 50 minute sessions (e.g. a one day per week, 150 minute class) must start at one of the starting times listed above.
Meeting Patterns:
  • Monday/Wednesday/Friday - for 50-minute classes that meet three times per week
  • Monday/Wednesday, Wednesday/Friday, Monday/Friday, and Tuesday/Thursday - for 75-minute classes that meet two times per week
  • One day per week classes may be scheduled on any day of the week, in accordance with the constraints noted below
Distributional Constraints:
  • Departments may schedule UP TO 50% of all of their classes below the 700 level during periods 2-4 ("prime time").

    Special Circumstances:

    • Very small departments will have difficulty meeting constraints regarding the spread of courses. Therefore, those departments offering six or fewer courses per semester at the 1-699 level do not have to meet this or the other percentage constraints, but they are expected nonetheless to provide a reasonable spread of courses over the day and week.
    • If departments offering ten or fewer courses at the 1-699 level in a given semester schedule at least one of those courses in the first period, they are permitted to schedule up to 65% (instead of up to 50%) of their classes in periods 2-4 ("prime time").
    • Zero or one-half course credits (labs, discussion sections, etc.) attached to any one-credit course do not count toward this constraint. If that lab or discussion section meets at a time different from the lecture time, only the lecture time is counted in determining conformity with this time constraint. Departments are encouraged, however, to schedule no more than 50% of these once-per-week sessions within periods 2-4.
  • AT LEAST 40% of all departmental course offerings below the 700 level must meet in some combination of three or more days per week (see "Meeting Patterns", above) or, for two days per week, in the MW, WF, or MF pattern.
    • Zero or one-half course credits (labs, discussion sections, etc.) attached to any one-credit course count toward this constraint. That is, if the lab or discussion section adds a third (or more) session to the course, the course is counted as a class meeting three or more days per week.
    • Departments can offer any combination of three day, MW, WF or MF classes in order to meet this constraint. The only stipulation is that if a department offers any MW or WF classes it must offer an equal number of the opposite pattern.
  • Departments may schedule UP TO 50% of their classes below the 700 level in the T/TH meeting pattern.
  • Each department can use one "wild card" when scheduling for a particular semester. The wild card allows any department to be out of validation by one class offering in only one of the first four constraints.
    • Computer-based labs of 50 minutes in duration, in courses requiring multiple lab sections, may be "nested" within 75-minute slots in such a way that not all of the starting times are the same as the scheduling model and not all of the minutes between sections match the scheduling model. The reason for this modification of the schedule in these cases is the limited availability of computer lab space and TAs. This particular modification of the schedule is permitted only for 50-minute computer-based labs.

Further Clarifications:
  • There are no percentage constraints on 700 level and above graduate classes.
  • Regarding the constraint about no more than 50% of courses in "prime time", and the requirement for matches of one-day-per-week seminars, the course validation program automatically accommodates an odd number of course offerings by giving the benefit to the department in such cases.
  • Half credit courses that stand alone, including house courses, performing arts courses, and physical activity courses, are not subject to the constraints, though departments are encouraged to provide a reasonable spread of these courses over the day and week.
  • For purposes of the percentage constraints, cross-listed courses count only for the department "owning" the course.
  • No TBAs for day and time are to be submitted, with the exception of independent studies.
  • Schedules must be validated through the final day of early registration. All departments will use the Departmental Schedule Validator, a web based validation program, to facilitate and check the constraint calculations, and to submit their course offering data to the Office of the University Registrar. During the drop-add period, the scheduling constraints need no longer be met.

Departments who wish to appeal any aspect of their course validation may do so in writing to the chair of the University Schedule Committee, Frank Blalark, via email or by phone (919-684-2813).

Revised January 9, 2013

Effective Fall 2010 the Higher Education Opportunity Act of 2008 (HEOA) requires all institutions receiving federal financial aid to "publish," in time for registration, a list of all required and recommended books and other course materials for all classes offered at the institution. This includes all schools—undergraduate, graduate and professional. The items we must display are:

  • Book title, including edition
  • Book author
  • ISBN number
  • Retail price

This is an effort to make more transparent the cost of education, as indicated in the following statement from the HEOA:

PURPOSE AND INTENT—The purpose of this section is to ensure that students have access to affordable course materials by decreasing costs to students and enhancing transparency and disclosure with respect to the selection, purchase, sale, and use of course materials. It is the intent of this section to encourage all of the involved parties, including faculty, students, administrators, institutions of higher education, bookstores, distributors, and publishers, to work together to identify ways to decrease the cost of college textbooks and supplemental materials for students while supporting the academic freedom of faculty members to select high quality course materials for students.
