They could solve a lot of school based anxiety and avoidance and burnout in neurodivergent kids by reforming the curriculum away from the ridiculous Gove curriculum, overly packed and designed for stressful summative assessment at GCSE, and stopping zero tolerance overly rigid rules in academy trusts that don't enable reasonable adjustments.
They would improve it further by ensuring all schools are capable of a wider offer than just GCSE, with vocational qualifications, ASDAN and functional skills assessments on offer to those who need examinations at a different level. Have this as an ofsted priority instead of progress 8 or baccalaureate that force schools to make children sit too many exams.
Then if they made class sizes smaller and made the space more sensory friendly, didn't have 1500 kids packed in like sardines in corridors moving between lessons, etc, that would help even more.
Much more inclusive than building loads more special schools to pick up the pieces of the children failed by an education system decreasingly fit for purpose.
