OK, we've had a lot of progress in the past few days. I once read on this website somewhere, that the teachers who "get it" the most are not necessarily the ones trained in gifted education (of which there are zero at my son's school). It's the ones with gifted children themselves. So, I recalled a conversation that I had a few months ago with someone on staff, who has a HG child. I sought her help (she carries a lot of weight at the school) and she is on it! She has helped me a great deal and she has become my advocate! We have another meeting scheduled and she will be with me. So, we are still pressing forward.
