Lil,
I never said it was wrong to choose a private school for its academic excellence! That is a valid reason though it may not be everyone's choice. My school suited me, but I know that by the sixth form, there were many people who felt that if they weren't applying to Oxford or Cambridge they were second class citizens. One girl in particular was very annoyed because the course she wanted to do wasn't even offered at either of these two universities!
Moving abroad isn't practical for most of us unless we want it to happen, in which case it is possible. Moving between two states in the European Union isn't the same as moving to a foreign country now is it??!
With regard to your point about sufficient books, I remember sharing books not once but many times at my school because there weren't enough to go round, and most of our text books were around 20 years old! I think it's a bit insulting to teachers to suggest that you only get good teachers in the private sector. The teachers at my state primary were fantastic, as were most of the teachers at my secondary school.
The point about an atmosphere of learning is a good one, but even this argument has its weaknesses - very academic schools tend not to teach the children the skills they need to learn on their own, a point which was made on the home education board as well. People I met at university who had had to fight to study, or study on their own, were far better prepared for uni and for life.
Grammar schools may look like the best part of the state system, but remember that you can't have grammars without having secondary moderns as well. I understand people who say why can't we have a system like the French, for example, where everybody except a few very rich kids, goes to state schools, and their schools are brilliant compared to our state sector.
I'm putting these sort of questions to see what other people think, or have decided, because I'm really undecided myself. We've considered lots of options, but don't have to make a decision for a few years yet. Many people like my parents made huge sacrifices in the 70s to take their children out of the state sector, and with hindsight, I question whether that was ever necessary or in the children's best interests. There was a variety of other options that would have led to university success, eg moving closer to grammar schools, sending children to state school and having extra tuition at home, or home education! Maybe all that money would have been better spent on other things.
I am really interested to hear what choices others have made/are intending to make.
