Registration Information

See below for important information about registering for Undergraduate courses at SPS, including registration timelines, adding and dropping courses you are already registered for, and auditing courses. All students register for courses using the CAESAR online student registration and records system.


For more information, contact the SPS Office of the Registrar.

New Student Registration

Before registering for courses, newly-admitted degree-seeking students must meet with an academic adviser by phone or in person. Call 847-491-5612 to schedule an appointment. Learn more about advising at the Student Services Resources page.

Current and Returning Student Registration

Current and returning students register for courses in CAESAR. A valid Northwestern University NetID and password are required to access the system. The registration timeframe for each quarter is:

Fall 2017:

Adding/Dropping Courses

All students (new and current) can change their registration status through CAESAR (add/drop, credit/audit). If you are withdrawing from all of your courses for the quarter, CAESAR will not allow you to drop the last remaining course on your schedule. Instead, you must fill out the Change of Registration Form. Do not send registration change requests to the course instructor or to the Office of Student Accounts; changes to registration can only be made in CAESAR.

Students who drop courses or withdraw from SPS may be eligible for a tuition refund, less any nonrefundable fees and deposits. The tuition refund policy is applied as of the date the request is received. For more information on refund policy when a course is dropped or for a withdrawal, contact the Office of Student Accounts.

To view add/drop deadlines, visit the Important Dates page.

Auditing Courses

Certain undergraduate courses may be audited. Students who audit do not receive a grade or credit; they attend all classes and participate in discussions but do not submit graded coursework. Most  courses in the following subject areas may not be audited: accounting, art, English writing courses, information systems, journalism, foreign languages, mathematics, physics, statistics and theatre. Some individual courses in other subject areas also may not be audited. See course listings for details.

The fee for auditing is $842 for SPS students and $420 for members of the Osher Lifelong Learning Institute.
