Is this student in the tiers for behaviors? Someone could do an FBA on the student to determine what the cause of the behaviors are and then a BIP to set a plan in action to decrease the behaviors. I know that a positive reinforcement plan is hard, especially in general education, but they do help. Mom may not know of community resources or the research needed to find them. Most parents are very receptive to possible outside sources, just make sure she knows it's her decision if she pursues farther action with them.

Mom may not know how to handle her son's behavior. Your response to her remark was an appropriate one. If this came up again you could suggest she and her son talk with the counselor about his behaviors. The counselor might could offer at home suggestions for the mother to try.

You should set up an appointment with the guidance counselor and an administrator. It sounds as if there are problems going on that are outside of the classroom.

Is the child active in any community programs? Does he have a male role model? Does he have any older big brothers? Could you possibly suggest the Big Brother program to his Mom or a male mentor to him and his Mom? The Mom might not have much family support around her and she might need additional family support and help in the community. Ask about activities that they could do together and suggest some things your school might be hosting to help them get involved. He might just be acting out due to him being bored and feeling a lack of male role models. Give him an opportunity to get involved and let Mom help as well.

I do not think that is an appropriate response for her son. I do believe you handle it correctly.
