Prerequisites, Corequisites and Recommended Preparation

It is the intent of Mendocino College to guide students into courses in which they will have the greatest chance for academic success. Therefore, students will find courses which have prerequisites, corequisites or recommended preparation in their description. Following are the definitions for prerequisites, corequisites and recommended preparation: 

"Prerequisite" is a course requirement that a student must meet in order to demonstrate current readiness for enrollment in a course or educational program.

Completion of the prerequisite is required prior to enrolling in the course. Successful completion of a prerequisite course means a grade of CR, P, or C or greater was earned; C-, D,F, NC, or NP grades are not acceptable.

"Corequisite" means a course that a student is required to simultaneously take in order to enroll in another course.

"Recommended Preparation" means a condition of enrollment that a student is advised, but not required, to meet before or in conjunction with enrollment in a course or educational program.


If a prerequisite was completed at another accredited college, please completed and submit a Prerequisite Equivalency Form, along with a legible transcript to the Office of Admissions and Records.  Documents may be faxed to 707-468-3430, scanned and emailed to, or hand-delivered to the Office of Admissions and Records on the Ukiah Campus, Lakeport Center or North County Center.


If you feel you can meet the requirements, or one of the conditions listed below exists, and can provide documentation, then you can challenge a prerequisite or corequisite. Complete and submit the Prerequisite Challenge Form and supporting documentation to the Office of Admissions and Records at the Ukiah Campus, Lake Center or North County Center. Criteria for challenging a course are:

  1. The prerequisite or corequisite has not been established in accordance with the District's process for establishing prerequisites and corequisites.
  2. The prerequisite or corequisite is in violation of Title V, Article 55201 Policies for Prerequisites, Corequisites, and Advisories on Recommended Preparation.
  3. The prerequisite or corequisite is either unlawfully discriminatory or is being applied in an unlawfully discriminatory manner.
  4. The student has the knowledge or ability to succeed in the course or program despite not meeting the prerequisite or corequisite.
  5. The student will be subject to undue delay in attaining the goal of his or her educational plan because the prerequisite or corequisite course has not been made reasonably available.
