How to handle a student who has elevated at schol

[Guest guest]

After a rough year at school we are preparing to give it another go. We are laying a lot out on the table, primarily wanting the school to recognize that when our son puts his head down and stops responding to them it is not the end of the world. He is withdrawing and will work himself out of this with a little time. If giving space we can deal with what brought on the anxiety.The question is,

though, how to handle situations where he has elevated and become a distraction. If he begins stimming and it causing a disruption, I don't want them clearing a room and threatening to call the police trying to make him stop (He wouldn't/couldn't comply with their directive to move to another room). I don't want them grabbing his stim and running off with it (like that worked really well last year). Last year my son ran from the school folk, locked himself in a room, and had restraints used on him. He also threw items at folk and got into tug of wars over possessions with school officials. Any good ideas on how a school can handle a kid who has moved to an impluse driven stage without it escalating into WWIII? Prevention is the goal, but I am

trying to develop some strategies.Thanks
