Shit just had a huge post measured and informative and it went tits up.
Sorry, i haven't read the whole thread: seeker and the grammar school appeal Vs private etc etc made my eyes glaze over a wee bit, but in answer to the OP.
We have our DD in a private school, in fact it's the local school: the next school is mainly a boys' school in a very deprived area and is 45 minutes away and the next school is in the other direction 30 minutes away, also a private one, with Eastern Philosophy three times a day. It's not a bad school, that one, but I didn't fancy the Sanskrit chanting.
So we pay fees, and don't go skiing, we don't have a horse, or a car, no, not even a beat up old volvo.
And we fit in very well: most of the parents both work, and are professionals like we are. Some parents are single parents and work, and some parents are SAHPs, with younger kids, or on career breaks. They're good fun on a night out - and we tend to clear the bar eventually as we drunkenly discuss the ins and outs, so to speak, of episiotomy, back to back labours, sleepless nights and raggy nips. Bit like here then.
The thing I like most about DDs school is the holistic approach towards mixing and friendships in the school. In no way is bullying of any kind tolerated and i would say that 99% of the kids who attend are deliriously happy to be there, wherever they come from and whatever their parents earn.
Most of the parents find the fees steep, and only a few who made a killing on property, or have Russian ties are in anyway loaded.
The multis don't seem to mind shelling out for the fees, the house in st trop, skiing etc. And there aren't that many multis actually. Most of the multis are pretty nice actually - IME the ones climbing the greasy pole are more judgemental and up themselves.
So you'll find that except for those who love to host coffee mornings, to give you the once over (all the better to judge you more accurately my dear), and comment ad nauseam about the Farrow and Ball interiors, and who are all watching what kindof designer bag/nanny you have, you'll fit in fine.
I just ignore those insecure clothes-horse cahs (whomsoever they are, not necessarily the multis), and it seems to be working out fine for us.
I second the financial advice to budget for at least 1K extra for extra classes and trips- good luck to everyone who's trying to get their kids settled in a school that supports and challenges them.
