Really interesting reading all of this. I have no idea what to do when my kids hit school age. My DH is Italian and he laughs at all the angst caused by the very complicated schooling in this country (as someone who hasn't engaged yet, what the hell is the difference between a local state school, a faith school, a grammar school etc etc - so complicated!) Complicated enough in fact to even think about leaving the country for their schooling and letting them go to the local state school in Italy - very few people go to private schools there - most simply go to the school round the corner.
I am dreading having to make all these choices for my kids - how easy it used to be when most kids went to their local school.
Anyhow, I went to a private school (20 years ago) on an assisted place (have they been abolished now?) - it cost £100 a term for me to go - Bargain!! I begged and begged to be able to go to private school because it meant going to school in the big city. I had a great time - mainly because I was academically bright and got pushed HARD and played in the orchestra in the local Cathedral etc. I ended up going to Oxford and getting my degree there. Some kids at the school HATED it and actually probably did worse than they would have at the local state school because they were made to feel inadequate academically even though they were probably still above average. They actually lost confidence rather than gaining it.
My 2 sisters chose to go to the local comp and really enjoyed it. They both did well and went to university and both still maintain they would have been unhappy going to my school because they would have missed their friends too much and are happy with how they did.
Neither of my parents went to University - they both did get into their Grammar School - but didn't have the aspiration for University - it just wasn't so much of the done thing then. They however, IMO, did the intelligent thing and sent us all to schools which suited our personalities.
So in summary, if we do decide to stay in the UK and find our way through the maze of schooling here, we would wait until our kids are 11 years old (send them to the local school in the meantime) and then decide (a discussion also WITH THEM) where they should go. And I am praying by then that we will have the money to send one or both of them to private school if we think it would suit their personality and they were desperate to go there.
