Students enrolling in a course with a prerequisite must complete that prerequisite with a “C” grade or higher before they are allowed to register. A course has a prerequisite to ensure that a student has the appropriate body of knowledge to be successful. Courses with a co­-requisite require that a student has successfully completed the course in a prior term or is enrolled in the co-­requisite course in the same term.

Please note: Dropping a class with a co-­requisite will result in a drop from both classes.

Usually a prerequisite is a course from a lower sequence of courses. For example: Students may not enroll in Math 142 (Elementary Statistics with Probability) without first passing Math 120 (Intermediate Algebra) or equivalent with a “C” grade or higher. 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 see the individual course offerings in the catalog.

Prerequisite and/or co-requisite challenge

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

Challenging a prerequisite or co-requisite

Prerequisites and co-­requisites may be challenged for the following conditions:

• 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.
• The student has the knowledge or ability to succeed in the course or program despite not meeting the prerequisite or co­-requisite. The student has gained the knowledge and skills in another fashion, for example, through work or life experience.
