Gabalyn it really depends on the school, by the high end private my kids used to go to absolutely was heavily skewed to MG kids, at least one 140+ kid per grade (50-60 kids) and he special ed team saw a LOT of bright but LD kids.

My kids absolutely found peers a lot more easily there (both miss HG+ and miss MG/2e). They catered better to my MG/2e kid at the time we were there, but I think they'd be far better for my HG+ dd than her current public school is and we certainly hope to get her back into a similar school ASAP.
