CLEP credits are treated a lot like AP credits. An individual med school may or may not accept the credit even if it is reported on a college transcript. School policies vary. To even be considered as fulfilling admission requirements, any CLEP credit must be listed as equivalent to a class offered by the institution issuing the transcript.
And any CLEP credits (like AP credits) carry the expectation that an additional higher level course in the same discipline will be taken at a 4 year university to supplement the CLEP credits. (Med school want to see a university-level grade in the discipline–even writing skills.)
