Which Kingston secondary schools are best for SEN/aspergers?

[Happytravellers]

Thinking of returning to Kingston from overseas, and wondering if other parents of teens are happy with SEN support TKA or Grey Court? My son is high-functioning, proficient at masking to fit in, but very anxious and would do better in an environment that feels nurturing.

Have you looked at Richard Chancellor?

Grey Court is actually in Richmond LA, but I know some with SEN are happy there.
