Registration requires that the student first be admitted to one of the schools or colleges of the university. All students should follow up with the student services area in their school or program office for specific procedures and information about registration.

All traditional and most graduate and professional students register for classes using WebSTAC .

Students enrolling in courses offered through WashU Continuing and Professional Studies (CAPS), or Summer School, register through the CAPS website.

Students interested in the Inter-University Exchange Program should consult with their academic advisor to discuss eligibility requirements and the applicability of courses toward a degree. Application/Approval forms are required to register.

Before Registering

Check the Academic Calendar for important registration dates and deadlines, verify the exam schedule, meet with academic advisor(s) and review course load policies before registering.

  • Class Schedule
    The class schedule for an upcoming semester is published several weeks before the advising and registration period begins.
  • Exam Schedules
    Not every course has a traditional “exam” as its final assessment; students should check class descriptions and details in the class schedule when considering taking a course, both to set academic expectations and plan schedules. Click here for Final and Evening Exam Schedule information.
    • Course Load Policies
      Unit limits and progress guidelines vary by program; check with the school and program coordinator for more information.
    • Undergraduate students in traditional, residential programs are required to register for full-time enrollment, which is between 12 and 21 units of credit per semester. Full details and options are published in the Bulletin.
    • Undergraduate programs in CAPS are designed to be completed on a part-time basis. Check with the school or an advisor for more information.
    • Graduate students in semester-based programs:
      Academic load status which determines the number of units that lead to be part-time or full-time status, is defined at the University level.
  • Re-enter after an absence
    Students who have taken time away from the university must formally work through reinstatement according to the steps outlined at their time of departure, typically  with their school and any other relevant offices such as WashU Cares or OISS. 
  • Registration Holds
    Certain required activities will result in registration holds if not completed. These may include payment of outstanding financial balances, advising check-ins or required vaccination documentation. Students should visit WebSTAC‘s Student Information menu and click on “Holds” to identify any existing holds and address them before registering.
Registering for Classes
  • Appointment Time
    A registration schedule and prioritization process is used at the beginning of fall and spring registration, which allows some groups of students to register before others. Undergraduate students who began their WashU studies earlier than others and therefore have less time left to fulfill requirements, register before newer students since they have a greater amount of time to fulfill requirements.

    Registration windows typically begin at 7:30 a.m. Central Time. Student-specific registration times are published in WebSTAC several weeks before registration begins.
  • RegistrationWebSTAC Help
  • Time Conflicts
    Students may not register for different courses that have conflicting meeting patterns. A course’s credit is based upon the amount of contact time and engagement between instructors and students over the course of the semester. Since time conflicts automatically reduce this engagement time, such enrollment is not typically allowed. For more information visit the Office of the Provost’s website.
  • Registration Permissions
    Students must review class description to verify whether they are eligible to take the class. Schools and departments may have additional advice or mechanisms to track eligibility for course registration; in such cases students will receive information from their school to prepare.
  • Registration Holds
    Certain required activities will result in registration holds if not completed. These may include payment of outstanding financial balances, advising check-ins or required vaccination documentation. Students should visit WebSTAC‘s Student Information menu and click on “Holds” to identify any existing holds and address them before registering.
Post Registration

  • Add/Drop
    After the initial registration period begins, students without holds may adjust their schedules by adding or dropping classes until the published deadline.
  • Grade Option Change
    Many classes are available to register for either quality grades (A,B,C, etc.), pass/fail or audit (no credit, no grade). Students are expected to pay attention to their program’s policies related to the grade options and minimum grades required to apply courses to their academic requirements, and register accordingly.

    Students in programs that allow it, may have room in their schedules to explore courses to take on a pass/fail or audit basis. If they later wish to adjust the grade option, they may do so until the published deadline. After that they are not allowed to adjust grading.
  • Waitlist
    Some courses, if no seats are available, may offer the option to waitlist in case seats later become available. Depending upon the policies of the offering unit, if seats become available waitlisted students may be registered administratively or automatically registered if a previously registered student drops the course, making that seat available.

    While notifications are sent in such cases, students are nonetheless expected to periodically check their registration to verify their schedule and obligations. Typically, waitlisted students are expected to behave as if they are registered (check the Canvas website, attend class meetings) so if they eventually gain full registration, they are not behind the rest of the class.
  • Withdraw
    Students may withdraw from a class after the drop deadline and before the withdrawal deadline. Course withdrawals are permanently noted in students’ records and on transcripts with with an administrative W grade notation.

    Students are expected to be familiar with their programs’ policies on the impact of withdrawals on academic standing, as well as any impact to their status if they are international students, or if they receive financial aid.
  • Deadlines
    Students are responsible for their own status at the university. Students are expected to engage with all registration processes, whether their programs offer self-service or administrative registration, including ensuring their registration is reflected accurately by the relevant deadlines.

    These deadlines affect financial aid, immigration status, the availability of services such as health insurance or stipends and accurate compliance reporting.
