As for the school -- I'm hearing whispers suggesting the opposite: "We've not had a kid like him before and don't think there's anything we can do within the school."
I think that may be more likely. Statistically they probably have never seen it. If you didn't have scores and they just met your child, I am sure they may say something suggesting that they have seen lots of kids like that go through their school and they did just fine. That's why we had DS5 tested before school because I didn't want to get that and when they saw the scores they didn't say they had seen lots of kids. They said some okay things at the meeting, but one thing they said was a story about one kid who skipped 2nd grade and that he still has friends in highschool and is doing well even though he is a little smaller than his peers. They were attempting to hint that one gradeskip is okay, but more than that is not good socially. That was their ridiculous point. I thought that was quite and ignorant story to say, but I am sure it was well intended. They just haven't seen it and don't know.
