Course prerequisites

Students wanting to enroll in a course with a prerequisite must satisfactorily complete that prerequisite before they are allowed to register. A course has a prerequisite to ensure that a student has the appropriate body of knowledge to successfully take the course. Courses with a co-requisite require that a student be enrolled in the co-requisite course.

Usually, a prerequisite is a course from a lower sequence of courses. For example: You may not enroll in Math 142 (Elementary Statistics with Probability) without first passing Math 120 (Intermediate Algebra) with a “C” grade or better, or the equivalent. Usually, a co-requisite course is a lab or a course that provides supplemental instruction.

To see which courses have prerequisites and/or co-requisites you may look at the individual course offerings in the catalog or the DVC website at

To register for a course with a prerequisite
If you have taken the prerequisite at DVC during summer 1999 or later with a “C” or better, your prerequisite will automatically be cleared when you go to register. If you took the course at DVC, CCC, or LMC prior to summer 1999, you must contact the Admissions and Records Office to clear prerequisite requirements.

If you completed the prerequisite at another educational institution the Admissions and Records Office will need to clear your prerequisite requirement prior to your registration appointment time. To clear a prerequisite you must submit a completed prerequisite form along with your supporting documentation. The prerequisite form is available at You may submit your form:

  • in-person

  • mail

  • fax

If approved, your prerequisite will be cleared in 48-72 hours and registration block removed. If denied, you will be notified via your InSite email account.  All prerequisites must be posted before you can register online.  If you register in-person, submit your Prerequisite Form and official or unofficial transcript 48-72 hours prior to in-person registration.

Prerequisite challenge
Students who are denied enrollment in a course because they do not meet the prerequisite requirement may challenge the prerequisite. Challenge petitions are available in the Admissions Office.

How to file a prerequisite challenge
Students must file their challenge before the first meeting of the class at the Admissions Office. If space is available, the student will be enrolled in the course pending the outcome of the challenge.

  • If the challenge is approved, the student will remain in the course.

  • If the challenge is denied, then the student will be notified that he/she has been dropped from the course.

  • If the challenge is not acted upon within five working days, then the student will be allowed to remain in the course.

Challenges for the following reasons are reviewed by the division dean who has final approval:

  • The prerequisite is based on health or safety and is either not valid or does not apply to a particular student.

  • The prerequisite is discriminatory on the basis of ethnicity, religious belief, political persuasion, age, gender, or sexual orientation.

  • The prerequisite course has not been reasonably made available at DVC.

  • The prerequisite was not established according to state law.

Challenges claiming that the student has gained the knowledge and skills in another fashion, for example, through work or life experience, are reviewed by a faculty committee, whose decision is final.
