Meant to, yes. It's one of the reasons (of many) that I'm opposed to uniform - and this is coming from an educator.
We are in a COL crisis and some parents are going to be broken by the cost of kitting their child out for secondary school, as we've just done. Ridiculously proscriptive and exacting specifications, even down to three separate colours for uniform, PE and 'games' socks (all extra money). Separate pairs of trainers and football boots. Everything must have logos, no plain substitutes permitted. And the hideous feel of the polyester fabric, especially of the PE kits, which for years I've avoided buying for environmental reasons. Then there's everything from calculators to the myriad different pens etc they'll need, and doubtless there will be books in the future too. My own job has entailed spending nothing less than thousands £ on books.
Part of my education was in the US - I've rarely seen a school with a uniform there - ditto on the continent. And in both cases, academic standards tend to be higher than in Britain. And gods help you if you have a kid with SEN. The cost of diagnostics in my DS's case was nearly £1200 for dyslexia/dyspraxia reports (we are in a low-funded LEA). Adding ridiculously expensive smartphones into the mix is an insult on top of all that. It will really cause some to struggle.
I know the fixation on uniform is baked into UK culture, but IMO it's completely unnecessary. As UK parents, why do we put up with this? Sorry for the thread derail - but it's a particular bugbear of mine.
