Remember that a 'good state school' for a child with SEN isn't often the same as a 'good state school' for a child with SN. All my friends send their children to an OFSTED outstanding primary school 2.5 miles from our village. We were confident that she was going to go there with 1:1 support. It was awful
- They kept us waiting for 20 minutes in the foyer (tiny, and DD1 doesn't do enclosed spaces), they waved dismissively at the SEN rooms, they said 'you can leave her to play' when DD1 kicked a fuss about the play area, despite us having told them on the phone that DD1 needs constant supervision and 1:1 care, they just clearly had no idea about significant SNs. They'd had a few children with dyslexia and so on, and one with visual impairment, but no other significant SNs, and it was clear that they would not cope with DD, despite saying they would. They said that we had to get the best statement we could 'or they wouldn't be able to support her'.
The local school which had a mediocre reputation welcomed DD1 first, then us, changed the route around the school because DD1 saw something she wanted to look at, offered to look after her in a classroom while we looked around the rest of the school, and assigned her a buddy who had been at her preschool, so she knew her. They let her join in. At a later visit, the deputy head heard her screaming in the SENCO's office, and left her classroom to come and invite DD1 down to her class for milk and snack. They said 'don't worry what the statement says, get the best you can, but if she needs 1:1, she will get 1:1', and they assured us that they already had a child whose parent had resisted statementing, but clearly needed 1:1, so they were initiating SA and in the meantime giving full 1:1 out of their own budget. They scored 'good' on OFSTED.
I can tell you which school was outstanding for SNs 
As it is, DD1 now goes to a Special school. 10 children in her class, with 4 teaching staff, plus often their are helpers. The site is secure and safe, so it reduces the need for 1:1, because any metal struts in the playground have padding, like softplay, doors have two handles, one high, one low, so she can't escape, etc.
