I’m not sure what disgusts me more, that such an institution of youth torture masquerading as a school is allowed to exist and does so on the tax payer’s dime*, or that they are apparently actually succeeding on the shallow metrics schools are so often judged on, giving the folks who are okay with doing horrible things as long as they get the results they want ammunition they can use to push similarly horrible things. Good ends don’t justify evil means and this school makes me think of school setting villains like Umbridge from Harry Potter or The Trunchbull from Matilda.
*Honestly, it feels a bit off to use the common name for the US 10 cent coin when talking about something in Britain, but best I can tell from a little googling, none of the modern British coins have catchy nicknames and are just a number of pence and I have no clue if this idiom has a British English equivalent.
