I teach pre-K in a public school. Last year, one of my students was suspended for freaking out on the bus, throwing things at the driver and calling her a witch (but with a b).
It kind of ticked me off because this child disrupted my class with outbursts like this ALL THE TIME. He threw chairs, he punched and kicked me and my aide, spit in our faces, screamed obscenities at us, etc. But we were told over and over again that he couldn't be suspended because he was pre-K. He was in the system, being tested, etc. But it wasn't helping us during the process! He is now labeled emotionally handicapped and in an 8:1:1 classroom.
