I'm not going to give you a hard time @OneDeepReader thank you for acknowledging things.
I do agree it is bankrupting LAs.
We are starting to see a shift locally towards specialist settings opening stand alone classes within mainstream buildings. If this is done well and funded properly it would actually be a cheaper solution. So say 8 children with a teacher and 2 TAs with a self contained classroom, playspace and toilets is much more affordable.
A huge part of the problem is everything was shut down in the name of inclusion and budget cuts. Then because these children still exist and can't just be forced to cope or thrive ina class of 30, it became a lucrative industry for independent settings. Theres only a handful of LA run settings here and twice as many independents.
Now we have the go ahead to move my daughter to a specialist, the only one that looks able to meet her needs is an independent specialist. There should be a LA run option but there isn't.
