If you will not satisfy a prerequisite through the above criteria, contact placement testing or learn more about reading and writing placement tests or math placement tests.

Please be advised: Unofficial documents can be used for prerequisite purposes, but official transcripts are required for full evaluations. When a student submits a document, it is considered unofficial. In order for a transcript to be considered official, it must be sent directly to COD from the issuing institution.

Once a transcript is submitted to the College of DuPage, it cannot be returned to the student and becomes the property of the College.
