Why is there a crisis in special educational needs?

There’s huge pressure on special educational needs and disabilities, known as SEND. The number of children and young people who need extra support has rocketed as more and more are diagnosed with autism, adhd and other mental health conditions. It’s led to a funding crisis which is putting a strain on council budgets which pay for the extra help.
