Inclusion They are words, guidelines. They don't override the Education Act.
I think it might be worth pointing out here that very very few children actually have 1:1 specified. But where they do it MUST happen.
Examples of where at child has NOT got 1:1 specified:
School to be provided with Band E funding to support X
X to have access to 1:1 support and small group work up to 15 hours
School to provide £7k of funding to support X or 20 hours
X will benefit from 6 hours 1:1
These essentially say 'Child needs support, probably costs this amount, do what you like'.
The MAJORITY of statements are written like this. In fact probably ALL statements that haven't been through the tribunal system are.
I personally think that the reason they aren't written better is because the school has failed the child by not raising it with the parents that the statements aren't specified and quantified as they are supposed to be, but ultimately, it is just mean, not actually law-breaking, and it allows the schools to use their resources flexibly.
