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 program director/department head or Vice President for Academic Services.
