The academic and calm children who want to learn and are neurotypical get on very well with my children and they need a school with those children, with smaller classes.
I don't think you can legally make 'calm' an entry criteria. Academic ability would be grammar schools but they certainly don't have smaller classes. Children who are academically able are generally expected to cope in larger classes.
Children with violence and behaviour issues need a school just for them with appropriately trained staff and proper boundaries.
These exist - PRUs. The threshold for being sent to one is extremely high though. We also need more of them.
Children with learning disabilities need enough SEN school places to go to as they cannot access the national curriculum
Certainly we need more special school places for pupils who cannot, despite best efforts, access the national curriculum.
Children with various other non-academic talents should be able to go to schools with specialist teaching in these areas while doing core subjects so that they don’t have their self-esteem crushed and are not made to feel worthless and can actually develop their equally valuable non-academic skills
This suggestion comes up a lot. It's the old grammar schools for the able, vocational schools for the less able system which was abandoned because it didn't actually do what it said on the tin. It's implied that children who are 'less academic' have 'other talents'. And that academic children do not have those 'other talents'. Whereas in reality there are children who are academically able also are good at sport, or drama or product design or whatever, and many children who are not amazing at maths or science are also not amazing at the other subjects. You also get kids who are great at maths and crap at English. Are they academically able or are they doomed to the 'other talents' school where their ability in maths is reduced to 'practical maths'?
And at what age would these 'other talents' be identified and kids filtered off into their appropriate schools? This was tried a few years ago with the UTC model where kids went off to 'more vocational' schools aged 14. The vast majority of UTCs were failures and closed very quickly with dreadful results.
Labour also tried the 'specialist school' thing pre-2010 with schools identifying a specialism and being awarded extra money for teaching it. There were schools with a language specialism, a sports specialism, a science specialism. That was mainly crap and also abandoned. At aged 11 kids mostly don't stand out in any clearly defined area and parents don't want to send them miles away to the 'sports school'. They want to send their kid to the local school where they can discover their talents and try a whole load of stuff out.
An “autism unit” in a mainstream state school will not help my children in any way. Will subject specialists teachers come to the “unit” and teach them in small groups like they need? No. It will be the same as now at primary
I've got a friend who teaches at a school with an autism unit and they didn't describe it like you think it is at all.
