But don't think that before the Tories elements of sex education was not provided by third parties.
You are right, as I've said.
But education wasn't up for grabs by as many private companies and charities as it is now. LEAs and the gov itself had content provided for schools to teach. LEAs, have been dismantled and private companies have sprung up. Eg, an LEA ict advisor who taught me went off and set up his own company for schools to buy in directly. That's Tory policy. The local LEA art advisor gave up (I think was also demoted) as no one came to his sessions as everyone uses twinkl.
Health visitors and school nurses had a lot more input into schools than they do now.
There were books and schemes you could buy (particularly music which is v hard to teach if you are non specialist primary and needed cds of music) but for the most part you could use what the gov provided.
It wasn't perfect. And definitely would have had to evolve. And I've no idea what it would have looked like under the curriculum they tried to bring out.
I'm commenting specifically on why schools buy in outside people and schemes. They're doing it for most subjects, including literacy (eg read write ink.) even that was all government led previously.
We've just signed up to a massive maths scheme which we've all said was basically the national numeracy strategy file re booted online.
EDI would have probably evolved anyway and yes, could have been an issue of Labour had grabbed it as they have out of power. As shown in wales.
I've no idea if this twitter thread is true though... twitter.com/lascapigliata8/status/1546070372314931201?s=21&t=YRqMUAeggCcK5LyNWqH4bQ
