Overcrowded specialist schools: ‘We’re teaching in cupboards’ www.bbc.co.uk/news/education-64418797
The shortage of places in special educational needs schools is a problem across the UK, with unprecedented demand for support.
Advances in life expectancy, more awareness and better diagnosis means there are now more children and young people with needs that are difficult to meet within mainstream schools. The pandemic has added to a system already under pressure.
Over the past five years, the number of children and young people being educated in specialist schools and colleges in England has increased by nearly a third - to 142,028 last year.
We found that just over half (52%) of SEND schools had more children in classes than their number of commissioned places.
Nationwide, the number of pupils with EHCPs has risen by 50% since 2016, to just over 355,500 last year.
Money for specialist schools comes from the high needs funding given to councils. Per pupil funding at specialist schools starts at £10,000 per child and is topped up further depending on need.
If a school takes on more pupils above their commissioned places, it won't necessarily receive the full high-needs funding for each additional child - that's a decision for the local authority.
Despite an extra £400m in high-needs funding announced in the Autumn Statement, the Local Government Association (LGA) says councils are facing "significant financial challenges" and need long-term certainty over funding to support children with SEND.
Louise Gittins, a councillor and chairwoman of the LGA's children and young people board, has told the BBC that if no action is taken, councils will be in deficit by £3.6bn on SEND spending by 2025.
What's actually happening is that private companies are setting up send schools and alternative provisions left right and centre for children who've no appropriate place in state send schools.
It's costing some LAs as much as 70,000 per pupil to send them there.
