I am not OP but this is very helpful. Along with the qualifying IQ test (Full Scale 145, Verbal 146 and I compute GAI at 154 (assuming I did it right), I included writings from a journal and workbook math computations and video. One of the struggles for me is that our child seems a "kid" at home but when we meet same grade peers their level of understanding just seems a chasm away. It is hard to show that. I am hoping the recommendations will make that clear. Funny, all this "concern" over just trying to find a "place" for our child to have friends at a similar level of interest and engagement.
