about open university


Open University Enrollment allows students not currently admitted to CSUF to take courses from the regular University schedule of degree classes.

You may request to enroll in courses at the undergraduate level (100-400 level) where you have read course descriptions and can acknowledge you meet the stated prerequisites or the equivalent of those courses. Some academic departments may ask to see an unofficial transcript at the approval level.

Graduate-level courses (500 level) require additional consultation and approvals before you may add the request-to-add permission process. Please consult directly with the graduate advisor/program before requesting to add this type of course.

Although students may request to add closed or wait-listed classes, Open University Enrollment is on a space-available basis.

Registration during the Winter and Summer terms allow for enrollment directly online through this website. Please read those directions and timelines.

Registration during Spring and Fall semesters is a paper registration request permission to add process at the start of those semesters. Please read those directions and timelines.
