A line of students walk toward class during the summer.

Welcome to CU Boulder Summer Session! We're excited you've decided to study with us. First-year, transfer, graduate, or nondegree and guest students can find application instructions in the How to Apply section.

If you have questions or are unsure whether you fit into the "new student" category, please contact the CU Boulder Admissions Office at 303-492-6301 or admissions@colorado.edu.

Once admitted, you can enroll for classes on a first-come, first-served basis beginning March 6. We encourage students to enroll early to improve their chances of getting into the classes they want.

Learn more about when and how to enroll using the How to Enroll section.

If you have any questions regarding Summer Session, please reach out to your academic advisor. Nondegree students should see a Continuing Education academic advisor.
