Completely reforming Ofsted would be a major thing that would help people’s workload, especially in Primary when it comes to subject deep dives. I would say scrapping it, but that is a pipe dream. Remove Deep Dives, remove one-word judgements and end job losses/forced-academisation if the result is less than Good. That could be done overnight (Wales removed one word judgments) and would be free.
Cutting down a quarter of the curriculum would help and would also be free. It would make children less stressed and maybe they’d enjoy and remember more of the stuff because they would have had a chance to consolidate and embed the learning
Scrapping SATs/phonics screening/baseline would be free and would stop the incessant focus on teaching very specific things and teaching to the test rather than providing a rounded enjoyable curriculum. It might make children happier and want to go to school more which would help attendance, but governments like having things to measure, so can’t see those going.
A lot of the other possible solutions will cost a fuck tonne of cash:
More PPA needs more teachers.
More special school places need more buildings and more teachers.
Funding SEND in mainstream needs more money for support staff.
Ultimately though, people don’t want to join teaching and loads of those currently in it want to leave, so something will have to be done.
