I realise this thread has gone quiet, but after stumbling across it and being shocked at the perception of Christ's Hospital as a school full of 'problem' children from 'dysfunctional backgrounds who are required to provide 'excess personal support' to their friends, I felt I ought to throw my first hand experience in. I spent my entire secondary education at CH from 2000-2007 and it was easily the best 7 years of my life. At no point was I, or any of my friends, called upon to provide excess care and support to any of the other pupils. The only support that was required of me was the kind that you would naturally, I hope, provide your closest friends when something upsetting happens (something upsetting being a break-up, being told off or getting detention etc). Of course when the first years arrive all the second years are assigned someone to look after, which I understand is normal in most boarding schools and, quite frankly, I imagine is a comfort to any parent sending their child to boarding school as it is hard to be away from home for a long time at the age of 11. If helping someone through home sickness is 'excess care and support' then I would suggest against boarding school in general - personally I feel it is a wonderful thing and teaches a child at a young age to care about other people and learn independence.
If anyone is bothered, in any way, about the ethnicity balance at CH then I suggest you do not go there as, to be honest, they will not take you and most definitely will not want you. Racism and prejudice (both the racial and financial kind) are not tolerated. End of. And, to me, that is exactly what makes the school great.
Also to clear up this 'full fee paying issue', CH has always admitted full fee payers however the intake is limited to, I believe, 6% in the founding charter. Whilst I was there they only took in 3% however the new headmaster has increased this to the full 6% due to the national financial instability. I'm afraid the view that most parents in the position to pay full fees will not choose CH is a very misguided one. That small percentage of places is often the most highly contested and many heads of private prep schools recommend CH - it was recommended to my parents as my prep school head teacher felt I needed a bigger school with more opportunities than the local Surrey private schools offered (not because I was a "problem" child, I might add).
This is the next point - you have to pass 2 entrance exams to get into CH. It provides a top education to children whose parents can't afford it, but the children do also have to get in. It is one of the most competitive entrance procedures out there. Plus it is not only based on academics, your child is also interviewed and spends a weekend at the school so that they can see how your child interacts with other children and whether they are suited to boarding school life. It benefits both parties and is a responsible way of ensuring, as far as they can, the happiness and well being of their students.
If you send your child to CH, then they will come out the other side as a very well rounded, highly independent person who is not afraid to work hard or stand up for themselves.
Money is not an issue and, certainly whilst I was there, I never knew nor cared what anyone's personal financial background was. It is an equal and level playing field and if a prejudice free cohort full of bright, outgoing children is not what you want then fair enough, but, in my opinion, you would be missing out on a great start for your child.
As a final note, I will add that I am the only one of my (non-Christ's Hospital) friends who looks back fondly on my school days and has been back to visit. When I told one of them I was going back again next year they couldn't understand why. They couldn't even understand why I would go back the first time, let alone again, however most of my CH year have been back to visit and I suspect will continue to do so. It's more than a school and it's very special.
