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.
  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 2020, Effective Fall 2012)

Time Periods: Monday through Friday (note the "nesting" of 50-minute courses within 75-minute courses)
Period 75-Minute/150-Minute Classes 50 Minute Classes
1 8:30 - 9:45 8:45 - 9:35
2 10:05 - 11:20 10:20 - 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, and must not end within the gaps between 75-minute time periods. In other words, all classes meeting in 75-minute and 150-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.
  • Classes that overlap time periods must overlap by at least 20 minutes.
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 and must align with 75-minute course start times. One day per week classes should not conflict with the distributional 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:

    • 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").
  • AT LEAST 40% of all departmental course offerings below the 700 level must meet in some combination of three or more days per week 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 classes and two-day classes in the MW, WF or MF patterns 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 TTH 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.
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", the course validation program automatically accommodates an odd number of course offerings by giving the benefit to the department in such cases.
  • 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, internships, and study away courses.
  • 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 via email to the Office of the University Registrar.

Revised January 2020

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.
