Re: fit: Schools have personalities just like families do. Kiddo has a friend who I always thought wasn’t quite a fit for his own family- which is quite gregarious and he is more introverted. It is kinda like that.
The elements that go into school fit tend to be how intensely the competition is felt, how college-y the campus is, how involved the adults are in a kid’s life, how strict the discipline is, how structured study hours are, how remote/isolated a school is, how big the school is. Traditions, how they build community, etc. That kind of thing.
