This is very very necessary and basically impossible to actually get from the administrations. My wife has had kids who violently disrupted her class 3+ times a week, to the point where she had to evacuate 20+ other children from the room for multiple hours at a time (I'm not exaggerating at all).

We finally sat down and I helped her write a specifically worded email (finally got a good use out of all of that HR training as a manager! ha) to trigger the right response from her admin.

Any shitty single kid can ruin a classroom for the rest of their peers. And the system doesn't allow for any consequences. It's massively disappointing.
