UC Berkeley Extension courses are open to the general public, unless otherwise indicated. Any course prerequisites are listed in the course descriptions. Enrollments are processed in the order received, so we recommend that you enroll early to ensure your spot. Payment is due at the time of enrollment unless otherwise specified in the certificate, course or section description. If you require special accommodation, please visit the Disabled Student Services section.

On our website, you can search for and browse courses and programs of interest. When you are ready to enroll in a course, add the course to cart, create (if you are new to Extension) or log in to your student account, and proceed to checkout. Once your enrollment is complete, you will receive an email receipt and confirmation.

If you need assistance with registration or have questions, please call (510) 642-4111, Monday–Friday, 9 am–4:30 pm (PST).

Students are only permitted to have one student account with UC Berkeley Extension. Please call (510) 642-4111 for assistance if you accidentally created multiple student accounts.

Unless otherwise specified in the program, course or section description, you are not officially enrolled until all fees are paid in full. All fees are subject to change without notice.

Textbook information is listed in your course section. You may purchase your textbook from any vendor, but make note of the ISBN as publishers frequently update editions.


  • Courses with 6 or more meetings: You can add or drop or transfer to a different course up to the second class meeting.
  • Courses with 6 or fewer class meetings: You can add or drop until 1 day before the first class meeting.
  • Ongoing online courses: You may drop within 6 days of registering to receive a refund.
  • Fixed-date online courses: You may drop within 6 days of the course start date.

No refunds or credits will be issued after these time periods.

Drops without transfers are subject to a $50 processing fee.


Your name is added to the waitlist if your requested course section is full. On the website, full sections have a Join Waitlist button. You will be notified if space becomes available, and you will have 24 hours to contact us if you wish to accept the available seat. Instructors are not able to approve you to enroll in a wait-listed course.

Before enrolling, you are welcome to attend the first scheduled class in a course of 6 or more meetings if the course has available seats. For courses with 6 or fewer class meetings, you must be enrolled to attend. UC Berkeley Extension does not offer course auditing, and attending a course beyond these days is not permitted.

Tuition refund deadlines and policies are strictly enforced. In cases of extenuating circumstances beyond your control that prevented you from dropping before the tuition refund deadline, you can submit an appeal. Official, supporting documentation is required for all appeals. Appeals should be sent to extension-appeals@berkeley.edu.

Appeals are most commonly approved for personal injury or illness, death of immediate family member and military transfers. Appeals are generally denied for reasons related to employment, perceived quality of instruction or dissatisfaction with a course, dropping courses to avoid low grades, financial hardship, missing a deadline or failure to review policy.

Regardless of the appeal decision, a non-punitive grade of "W" (for withdrawal) will remain on your academic record. See our website for information on grade appeals.

UC Berkeley Extension has the right to approve or deny any appeal. The review process can take 3–4 weeks.
