Prerequisite Clearances

​​​What is a Prerequisite?

prerequisite is a class that must be taken before you can enroll into another class. (Ex. complete ENGL A100 before being able to enroll into ENGL A101)


What is a Co-requisite?

co-requisite is a class that must be taken at the same time as another class. (Ex. BIOL A225 and BIOL A225 lab 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 (official/unofficial)* from an accredited college or university that shows you have completed a prerequisite course with a "C" or better and is considered an equivalent course at OCC. Note: A "C-" grade is not considered a passing grade at OCC and will not be accepted. Attempting a prerequisite class and withdrawing from the class with a "W" does not meet the criteria for clearing a prerequisite (A "W" is a notation not a grade).

*Submit official transcripts if you wish to receive course credit/units towards Degrees, Certificates or General Education Certification (CSU GE Breadth or IGETC). Official transcripts must be submitted to Enrollment Services.

  • AP Scores that are "3" or higher. For which AP exams we accept, please refer to the OCC Catalog. To access your AP results please go to Sign in with your account information or create a new account. Click on the "AP" tab at the top of the page.

Processing Clearance Forms:

Please allow 3-5 business days for your request to be processed. We encourage you to submit the Clearance Request Form well before your registration date.  You can check your registration date by going to MyOCC >Registration >Registration Status & Checklist. Once your request has been processed, you will receive an email to your student email.

Challenge Process:

Clearance Request Forms that are denied, you can challenge a prerequisite based on previous experience or knowledge. Submit a Prerequisite Challenge Form to the respective division office in accordance with the Matriculation guidelines established by the State. Note: A clearance denial determined by a grade lower than a "C" in a prerequisite course cannot be challenged through this process.
