Ah agree with that smee if the child is not happy.
I was lucky that my parents never followed the school of thought of one school fits all approach, i.e. the educational path that my sisters led was very different to what they did with me, and this wasn't due to money, this was due to personality.
My sisters are ultra competitive and would succeed anywhere in life, because not only do they compete against their peers but they also compete against themselves always aiming for personal bests, therefore for them, any school would of got their full potential, so they were sent to standard schools. All 3 passed the 11+, 2 went to local comps because they wanted to, and didn't want the pressure of grammar as were putting enough pressure on themselves, the other one went to grammar, because she wanted to be the best of the best.
I on the other hand was so uncompetitive and undriven, my parents knew I would be lost in school, so therefore I was sent to independent to have my attention focused, it worked for me.
Now I take the same approach with my children, they are all at different schools, because they have different needs. But I ensure that all of them are driven, but only at the rate and appropriateness for them. If I didn't think my children could cope with a school's style they would be moved.
