Ok, here is the new formula most educational systems have.
I know this is cynical and might make me be percieved as a raving lunatic however it is worth the mileage I can get out of it, lol.
Anyway, so being out of secondary education for a year now, makes me look back at the time I was there. I found out something during my contemplation, that it is very simple. If you don't behave EXACTLY the way others do, you have a disorder, if you not a submissive slave to the teacher, and socialize with the children, "peers", and adults you have a problem.
You must think, act and behave normal, otherwise you have a disability....
So, come up with a disability and label that child with it as a means of social control
