I am a teacher in a secondary school, and as I prefer to, I usually work with the SEN children and bottom sets. I have to say that there are many, many children who clearly suffer from ADHD/AS type issues who haven't been statemented, either because a statement is hard to come by or because of the stigma attached.
Those children with statements (few and far between) definitely do require extra support, as do many without.
My question is this: Even if you don't believe in ADHD and AS, do you agree that the children who fall into this category need and deserve extra support at school? If so, is it not useful to have a system whereby the issues are recognisable and can be dealt with?
I totally disagree with you that they don't exist, but I really don't understand why you are bothering with your argument. Surely it is patent that whatever title is given, support is still required.
Remind me of your point...
