Mr W was ecstatic when he went in with older kids. His first comment to me when I picked him up was, "Dad, they can talk!!" I imagine that putting him back in with his age peers would be like a scene from the Planet of the Apes where Heston meets the non-verbal humans.
DS15 was very upset by this same part of the problem back in his daycare days, when many of the kids literally didn't talk.
I don't know if TX still offers gradeskips by testing, but they used to - worth checking into to at least get the base grade right.
I think the private school kids have a higher percentage of NMS because they had higher IQs to start with - as there is a fairly strong correlation between income and IQ of parents, and a quite strong correlation between IQ of parents and IQ of kids. As we know, drill seems to have 'mixed results' with gifted kids - it benifits some of the time and produces worse results other of the time.
Good luck!
