It is not unusual for the student with Aspergers to "hold it in" all day and release their stress at home; their comfort zone. 

School is a very stressful place for the child with Aspergers Syndrome.  Social situations keep them in a state of confusion.  Environmental conditions cause sensory overloads.  The result is increased anxiety. 

Whenever a child is experiencing rage or simply acting out, attempts should be made to look for the triggers.  Reducing the anxiety may require a change in schedule, taking time off from school or eliminating homework.  Flexibility is key!
