I love Easton Country Day...all the kids do each class at the childs level...they get what makes gifted kids tick. I have heard really good thinks about Pierpont in Westport for highly gifted and beyond.

Foote in New Haven is worth a look.

Certain CT districts have very good public...it may be worth looking at neighboring districts.
