Students sitting in the grass on the quad at CU Boulder

We’re so glad you’ve decided to stay on campus this summer! If you’re a current CU Boulder student, skip the application process and go directly to the enrollment instructions for summer classes. If you’re a nondegree student, guest, or recent graduate, you will need to either activate your account or apply for Summer Session. You can review those steps under the How to Apply section.

If you’re unsure whether you fit in the current student category, please contact the CU Boulder Admissions Office at 303-492-6301 or

When you’re ready to enroll, you can do so online via MyCUInfo just as you would during fall or spring semesters. Students register for classes on a first-come, first-served basis beginning in early March, so enroll early to better your chances of getting into the courses you want. Use the How to Enroll section to find enrollment dates and other important enrollment information.

Some holds, including disciplinary and financial, may prevent you from enrolling in Summer Session, while other academic holds may not. If you have a hold, log in to MyCUInfo for more information about your specific situation and contact your advisor if you need additional help. Nondegree students may see a Continuing Education academic advisor.
