In my experience, private schools are heavily into resources, routine and enrichment. School
days run like clockwork to fit everything in. They do have slightly longer days in primary and quite a bit longer in high school, with Saturday school common, but not in all schools. Although weekend sports fixtures as they get a bit older. They tend to build physical activity into every day, and have lots of specialist staff too. I’d be a bit worried at what you were paying for if these things didn’t all happen.
DD (young end of primary school) has PE on Mondays plus outdoor learning, games on Tuesdays, Wednesday is swimming, Thursday is a sport that has an outdoor company in to run it. Friday outdoor learning. Music twice a week and French twice a week. After school clubs are a mix of sporty and fun. Starts recorder next year with the whole class and then private additional tuition becomes available the following year, although we’re currently looking for a drum teacher. Latin further up the school. Library trips every week, normally a school trip per term and residential start very early too. Heavily into the arts and school shows and productions.
Academically, they are pushed. But equally there is a lot of resource for kids who need extra support in particular areas. I would imagine they are working 6-12 months ahead of curriculum in most areas.
For what it’s worth, I grew up in a WC skint family. DH less so, but not rolling in it. We’ve made some very savvy decisions and it’s paid off for us. It was never a guarantee that things would turn out this way. I never expected life to be like this. We are definitely on the more “down to earth” side of families though. There is a lot of entitlement, but we actively don’t do that. We’re not twats.
Also, I would have been happy for DD to go to the local state school if things hadn’t turned out this way for us. I would still be doing reading and maths with her most days, and she’d possibly do a bit more out of school to supplement less resources in state sector. But many many people already do that, and often to excess. We wouldn’t have stretched ourselves to an uncomfortable financial position to fund private school. I’m extremely grateful that we can, but it wasn’t a make or break for me, or DH.
