“It’s not as if the decision that you make today is going to determine his academic future for the next ten years.”
It can be much harder later to switch schools when a student is in the upper grades, than to start off in a school where he has a good chance of fitting in and being happy for the next ten years. Harder to be accepted into the school, and harder to adjust to a new set of classmates. Sometimes switching is necessary and beneficial but it usually isn’t easy.
