Teachers don’t have to pressure parents in such overt ways; oftentimes they are a bit more roundabout than that. They can (and often do) just cause so much trouble for your kid that it makes you want to do “something” just to get the negative and destructive teacher attention off your kid.
I succumbed - I homeschooled mine. I don’t know who was more relieved - me for not having to put up with the teacher BS or the kid for not having to deal with the problem teachers.
Part of the problem is parents.
They don’t want to control their kids, so when the admin says the kid needs drugs, the parents think it’ll be a great way to control him! Wow, of course - he has a disease!
It’s not only the “victims” that use these bogus diseases as excuses, it’s the parents too. In cases like “ADD” and its fallout. That way they can tell everyone they just couldn’t control their brat because he has a disease.
