I think that it is best practice to remove all other students from the classroom when the student begins to become violent for the other student's safety. If this is a regular occurrence than the setting might not be the least restrictive environment for the student. It sounds like the parents are in disbelief of how bad the situation is if they are not concerned about the other students around their child. It may be helpful to record the student when they are havign a violent episode so that the parents can see how dangerous it is for their child and the other students in the class.

When this happens, it is important to first remove the other students from the classroom/area and ensure that they are safe. I would try to invite the parents into the classroom to observe their child, and try to make sure the child doesn't see them. If you have an assistant in the classroom, I would talk to them about a plan for handling this behavior.

I would create a barrier between other students and this student. You may have to take other children out of the room if he is targeting the students. The student may benefit from "his" corner. Have an area just for him to take a break in when his frustration level intensifies.

I would work the behavior specialist and have them nearby as a preventative for this behavior. In my internship we have also created a safe area for students who might be more vulnerable as well as plan on how to evacuate students during those time!

I have a student like this. Our procedure was to remove all other students from the classroom. Then, my CT will call the behavior specialist for assistance. If nothing else works, my CT has called the parent for assistance as well.

As other people have suggested, removing other students and documenting his behavior is a good start to minimizing damage and getting the parents on board. I personally would also suggest putting this students in a corner or seat away from other students with objects ready for the student to break/beat/manipulate. If the teacher can get the parents on board, they can provide these materials instead of or in conjunction with the teacher.

Assessing behavior and getting ready for situations are two ways to respond successfully to hostility and violence. Some of these include completing functional assessments, identifying the indicators of a violent episode, and creating individual crisis management strategies. To ascertain what purpose an aggressive or violent behavior serves for the student (what benefit is derived from the act), what environmental or physical factors are connected to the display of the behavior, and what communicative or other responses might be functionally equivalent, functional assessment is a prescriptive approach. For example, suppose a student receiving special education services or is being assessed for eligibility engages in violent, aggressive, or other dangerous behavior. In that case, functional evaluation. Also, recognizing the antecedents to help prevent the undesirable behavior. Analyzing the causes and effects of behavior is crucial for behavior understanding and modification. Understanding a behavior's antecedents gives us knowledge of the conditions under which it was rewarded and prevented.
