He sounds like he is high functioning. Usually Autistics do not relate well enough to other people to regard them as threats.
The special education classes are not the place for high functioning autistics. They would be if the special education teachers had the time and resourses to teach exactly what is taught in the regular classes. They do not, so the special classes can’t even teach what the slow regular classes teach. By putting this child in special class you will condemn him to a third class existence.
Take him aside and tell him to toughen up. Put him on the front row. Also, remeber you won’t have him next year.
True. Good ideas. I have started getting a few decent students next to him to help him stay on task, and that has improved things a bit.
