Prerequisite Clearance

What is a prerequisite?
A prerequisite is a course (or equivalent skills or prior experience) that you must complete with a grade of “C” or better (or possess) before enrolling in a more advanced course.  A prerequisite is a course needed before you may register for a subsequent course.

What is a prerequisite clearance?
If you are registering for a Chabot College course that has a prerequisite and you feel have fulfilled the prerequisite with a course you have taken or currently taking at another college or university, then you can request a prerequisite clearance by submitting:

  1. Prerequisite Override; or,
  2. Prerequisite Courses in Progress; or,
  3. Prerequisite Challenge, if your Prerequisite Override was denied.


Prerequisite Override

If you have already completed the prerequisite course, submit your request. Processing time is a minimum of two instructional days. (due to the current high volume of requests, turnaround time is about a week)

  1. In the body of the email, please provide:
    • Your name
    • The last 4 digits of your Student ID Number (W Number)

    • The name and number of the course(s) you want to add that has prerequisites (Math 55 or Chemistry 1A, for example).
  2. If you have NOT submitted official transcripts to Admissions and Records, you must scan and attach unofficial transcripts with this request that document successful completion (grade of C or higher) of the prerequisites for each course you want to add. Please be sure that your name and the name of the college both appear on the transcript.If you have already submitted official transcripts to Admissions and Records documenting successful completion (grade of C or higher) of the prerequisite course(s), no further action is required for this request.


  1. If you have NOT submitted official transcripts to Admissions and Records documenting successful completion (grade of C or higher) of the prerequisite course(s), please bring the unofficial copies with you.

Prerequisite Courses in Progress

If you are currently taking the prerequisite course at another college or university, you will need:

  1. Letter from the instructor on college letterhead with the following information:
    1. The name and number of the course
    2. Your name
    3. The grade the instructor expects you to receive
    4. The instructors contact phone number
  2. Submit by Email or In Person:
    1. BY EMAIL
      Scan and attach the letter from the instructor to your email request and follow the same email instructions as for Prerequisite Override.
    2. IN PERSON
      Bring in your letter from the instructor and follow the same in-person instructions as for Prerequisite Override.


Prerequisite Challenge

Reasons for challenging a prerequisite/co-requisite may include one or more of the following:

  1. A prerequisite is not made reasonably available to a student
  2. A student believes the prerequisite was established in violation of state regulation or in violation of the District approved prerequisite process;
  3. The student believes the prerequisite is discriminatory or being applied in a discriminatory manner.  (Discrimination is defined as prerequisite being arbitrarily enforced with some group(s) of students and not with others or having disproportionate impact on a particular group of students.);
  4. Student has documented knowledge and abilities equivalent to those specified in the prerequisite course.  Student documentation is required.
    The student must provide appropriate documentation when filing a challenge form. Documentation may include, but is not limited to, high school or college transcripts, additional test results, work experience, or writing sample. Prior enrollment in the course does not exempt a student from the current prerequisite of that course. You must meet the current prerequisite even if you were able to register for the course in previous semesters. Prerequisites do not have catalog rights.

What are some good examples of appropriate documentation to support my challenge?
Examples of appropriate documentation could include: transcripts, course descriptions, work experience, documented skill development trainings or workshops, and/or test scores. Being a “good student,” “knowing you can pass the class,” and/or needing the class for graduation, athletic eligibility, or insurance purposes are not examples appropriate documentation.
