Inclusionist: "Special School funding works differently."
It doesn't, you know. It may be that in the past there hasn't been specific funding allocated to the statement according to the needs of each specific child, but it remained the case that the special school got more funding than mainstream precisely because it was supposed to be able to provide things like 1:1 support when that was necessitated by the terms of individual children's statements.
Under the new funding regime, special schools get a basic £10,000 delegated per child, and top-up funding on top of that if the child's needs warrant it. Given that full time 1:1 support certainly costs more than £10,000 per year then current funding works as I said.
