You aren't under fire. You're just all making each other defensive. The more you talk about degrees and accreditation, the more it sounds like something you couldn't even impart on your own, because you aren't an institution.

I agree with you, okay. He has good instincts but he has...blind spots and fault lines and he needs to learn how to be - professional, for lack of a better word, before I'd hold him up as someone anyone could come to. But he's like me, he's going to talk to people and meddle whether he quite knows how to make it any better or not.

So don't tell him he needs training. Tell him you want to train him, and when would be a good time. It sounds like semantics but the implications are different. He might drag his feet a little now, see defensiveness above, but he likes to learn.
