TECEPs do not need ACE or NCCRS approval. Don't ask a school if they accept TECEPs.

Oops -- I had emailed the local CC earlier today asking about a TECEP approval for one of my children, and I might have made every mistake you said not to :p <sigh>
I shot the advisor a follow-up email, hopefully clarifying based upon your explanation here (which, btw, is much appreciated!).

I heard back from our local CC advising (who checked with Registrar). Because TESU is RA and also offers the TECEPs as courses, they will accept them as transfer credit.

I don't know about the "Big Three," but Ashford just explicitly told me they will not accept my credits earned at my prior institution -- with which they have a formal articulation agreement -- by testing out of them. These are courses I tested out of by literally taking the course's final exam. If I didn't take the course, they won't transfer it.
