My wife is working in preschool and wanted to have some examples to discuss with her. I know plenty of those for overrepresentation of AuDHD spectrum in IT (especially males), but don't know any for schools. Especially since women are often not that obvious.
I don't have statistics. My wife works in elementary special education. Previously to her current assignment to a classroom with assigned students she worked across the entirely of a large school system as adviser.
Anecdotal, but my cousin has ADHD (not the same, but there seems to be significant overlap) and is working on becoming an elementary school teacher
