I must pick up an earlier point that teachers at private schools do not have to be qualified. It is grossly inaccurate and to be honest, very insulting.
Not many people have mentioned the child - but often certain child do better in the private system. Some children are so together and bright they would be able to be left in a jungle and come out with all their gcses.
My situation is a little different - health issues mean that I need all the pastoral care they can give me - hence why we wanted to go into the private system in the first place. Currently my daughter is able to stay at school until 9pm, with lots of clubs and supervised prep.
Of course education should be one size fits all - state schools should provide all we need. But it's not an ideal world.
Be careful though - I have had some very negative experiences too with one school in particular - where academic results were all they cared about. I even had my family doctor (indiscretely) telling us that she treats a lot of girls from that school for stress and depression. So all is not perfect.
Pushy parents? Perhaps - in some cases. But there are children who need pushing - I was an example. My parents were very laissez-faire and I floated.
Personal choice of course but bloody hell, I never ever see myself as better. Why should I? An idiot can spend money, after all. But we have made a personal choice based on our circumstances....
