how to judge if the school's curriculum would fit your kids

[Anonymous]

dc is our first kid and only kid. we don't have any idea about kid's development and stuff.
since teachers in the daycare told us dc is doing very very well academically and socially. dc needs a little bit challenging curriculum. We are looking for a private school. one of the teachers happens to know green acre. she said green acre might be too easy for dc.
we went to all the school's open house and tour. basically when we went, mostly we look at the phiosophy and a nurturing enviroment. we really like green acre. but we don't know how to compare its curriculum to other schools. how do we know if it fits dc?
