That is worth asking @Airwaterfire
Within SEND there are lots of different groups, each with their own needs. It's not a one size fits all issue.
Some have SpLd and just need 'educational' help
Some have mental health issues
Some have ASD or ADHD
Lots have a mix
But there are also those who are outliers at either end of the spectrum.
Just as we would not write off those children who have intellectual disabilities that make learning extremely challenging, there are those with intellectual abilities than need equal help and support to prevent most of them joining the ranks of the mental health issue contingent.
How are we catering for all the groups within state schools?
Dear Bridget seems to like the idea of having ASD units within mainstream.
Are we going to have separate units for ASD, ADHD, SpLd, Mental Health issues etc in every comprehensive?
My guess is that the DfE are rapidly going to realise they have bitten off more than they can handle.
Or perhaps the big plan is to buy up all the closing private schools and repurpose them as Great British SEN Schools... followed by Great British School Taxi Service.
