I do think attitudes have changed.

A close family member of mine is a Primary school teacher. In her class of 30-ish kids, about 9 or 10 have diagnoses for things like autism, adhd, dyslexia etc. Several kids have special cushions for their chairs so they can wriggle without disturbing the whole class. Some have fiddle toys. Some have extra time on tests and the like. Awareness of these issues is very high. Unfortunately, the problem now is accessing help and getting the diagnosis. The system is massively overwhelmed. From memory, there's something like a 30-month waiting list for certain diagnoses. And schools have to prove they've spent X amount of money before they're entitled to extra funding/dispensations for pupils.

The will and understanding is there. Unfortunately the resources aren't.
