Many EWC courses have prerequisites that must be met before enrollment in those courses, and which can be found at the end of course descriptions. A course prerequisite is typically met by an appropriate ACCUPLACER score or by completion of a prerequisite course. However, in unusual circumstances a student may have demonstrated comparable knowledge or background equivalent to but different from the listed prerequisite. In those unusual cases the full-time faculty member teaching the course may grant permission for the prerequisite waiver. Adjunct faculty may waive course prerequisites only after consultation with the appropriate division chair or Vice President for Academic Services.
