I think if he is *in good company* in his HGT program than that's MG. If he is still bored or struggling to find likeminded peers in the program then HG would explain more.

Everyone uses the lables differently and things vary so much that a kid would be run of the mill gifted in one neighborhood might be a 'we have never seen anything remotely like THIS' in a different neighborhood.

Remember those scores measure unusualness not smartness.

Hope that helps
