They tried this crap with our son in elementary school...told them to go pound sand...any kid who could sit and flawlessly put together a Lego kit with hundreds of pieces wasn’t ADHD.
We found that he was seated in the back of the class, needed glasses and that he had a slight narrowing of the palate that affected his speech pattern.
All of that was fixed and he went on to be a commander in HS AFJROTC, Eagle Scout, OA Vigil Honor and on the Honor Roll every semester he was eligible.
