Prerequisite Clearances

​​​What is a Prerequisite?

prerequisite is a course that must be taken before you can enroll into another course (e.g. ENGL A100 must be taken before ENGL A101).


What is a Co-requisite?

co-requisite is a course that must be taken at the same time as another course (e.g. BIOL A225 and BIOL A225L must be taken as the same time).

Prerequisites and co-requisites are enforced at the time of registration and you will not be able to enroll into that course until the requirement has been cleared.

Clearing a Prerequisite and Co-requisite

Submit a Clearance Request Form to clear a prerequisite or co-requisite. One of the following must be included with your request:

  • College transcript from an accredited college or university that shows you have completed the equivalent prerequisite course with a "C" or better. Note: "W" and "C-" or lower will not be accepted under any circumstances.

  • AP Scores that are "3" or higher. For which AP exams we accept, please refer to the OCC Catalog.

If you need help finding out if a class has a prerequisite, watch our video on How to Check and Clear a Prerequisite.

Processing Clearance Forms:

Please allow 7-10 business days for your request to be processed. We encourage you to submit the Clearance Request Form well before your registration date. Once your request has been processed, you will receive an email to your OCC student email.

Challenge Process:

If your Clearance Request form is denied, you can submit a Prerequisite Challenge Form to the respective division office. Note: A Clearance form denied due to a grade of "C" or lower cannot be challenged through this process.
