Sources for accreditation

Does anyone use any sources for accreditation other than the Arts Award?

I'm specifically interested in courses that last a shorter time than the Arts Award.  We run intensive development weeks for young musicians and it would be nice to give them some sort of certification at the end but do not have time to run Arts Awards during the week.

It would be nice to be able to run something that was nationally recognised but an alternative could be to run something that would at least be recognised by local higher education institutions (with whom we have good relationships).  Has anyone explored this second route before?  If so, what were the benefits?
