“Oppositional Defiance Disorder” is a diagnosis that can get a student an IEP.
So a disruptive, violent child can show up to school every day - throw chairs, bring drugs to school - then get mom or dad to take them to the doc to diagnose them with ODD. It’s a manifestation of their disability.
“Inclusion” also means that these children need to be placed in the same classroom as all the other children. So 29 children are subject to the violence of 1.
Honestly, I suggest that you get into teaching.
Maybe sub for a day. Experience some of the gaslighting for yourself.
And yeah, being expected to just take the abuse is why there is a massive teacher shortage. The fact that everyone thinks their personal K12 experience makes them a master pedagogue is just icing on top.
