I think a lot of schools are totally insulated from the realities of family finances.
We've already received notice of two trips next year - each of them costing well over £1,000 - ordinary state school in an average area.
They have the usual 'if you're struggling financially' bit at the end, which, to me, shows how out of touch they can be. 'Struggling financially' is if you can't afford your basic bills and food - not that you don't have a spare grand here and there every time the school decides to send you an email.
Even aside from the very big-ticket events, they quite casually tell you what they've organised and that it will be £20 here, £40 there, £75 the next time - or even more. Maybe irrationally, it seems even more annoying when it's framed as a 'reward' for the kids; but presumably only one that they deserve if their parents have the money.
I know that it's a bit of a lose-lose situation for the teachers, but we're at the point now where they're choosing their options and thinking ahead to future careers and hoping that AI doesn't destroy them just before they qualify - and if you have a bright DC, the teachers are always enthusing about university: where they could go and what they should study.
My teachers did the same when I was that age, but it was a completely different scenario back in the days when governments wanted to encourage and support young people to go on to higher education, rather than making it the preserve of the wealthy and privileged again.
Schools often seem to really not understand that - whether it's a great educational opportunity, a big jolly or indeed committing to a lifetime of debt for university - you can't pay for them with intelligence, hard work and dedication alone.
