A “prerequisite” is a course a student is required to complete with a “C” or better, or a skill a student is required to have before enrolling in another course.  In limited circumstances and for only specified courses, a student may be allowed to enroll in and participate in the prerequisite course during the same term as the other course.  If concurrent enrollment is an option, it will be specified in the class schedule.  

A “co-requisite” is a course a student is required to take while enrolled in another course. All prerequisites and co-requisites are designed to ensure students have the skills and knowledge they need to succeed in a course.

Prerequisite and co-requisite requirements are established because it has been determined that without meeting them, a student is not likely to receive a passing grade in the course. A prerequisite or co-requisite also may be necessary to protect a student’s health and safety, or the health and safety of others. Additionally, courses taken without prior completion of the prerequisite may be denied credit upon transfer to a CSU or UC per articulation agreements, either at time of admission or upon petition for graduation.

An “Advisory on recommended preparation” (listed as “Advisory”) is a course or skill a student should have before enrolling in another course. Such recommendations are offered by the faculty who teach these courses, and it should be followed for student success. However, unlike a prerequisite or co-requisite, an “Advisory” is not required.
