First year SPED Para — what should I expect?

I will be a first year paraprofessional in a SPED class.

The classroom is for high functioning students with Autism, ADHD, and Emotional Disturbance who’s behavior in their Gen Ed classroom impede their learning, and their classmate’s learning. the program is meant to help them get back into the gen ed classroom.

The grades are K-2. What should I expect?
