I totally agree, , about how interacting with the parents could provide insight into his home life and its impact on his behavior at school. I don't have much experience in elementary school. However, with the student I mentioned from my third grade class, I did talk to his mother, very gently, and after speaking with her a few times, I reshaped my entire support plan. I realized that she had no interest in supporting her son aside from giving him medication. She didn't have interest in working together on positive behavior reinforcement or communicating about his needs at all. After my conversations with the mother and with my student, I realized that he felt quite neglected and alone at home, so much of his behavior was attention seeking. When I addressed his needs from this perspective, we had an amazing rest of the school year!
