I have a student that is constantly disrupting class. He turns to anyone nearby and talks with them. He makes rude noises. He smarts me off and he is hardly ever quiet. I sent him to the principal last week for refusing to work. She told me later that she talked with his mom and the reason that he is so disruptive in my class is because he doesn't like the sound of my voice. It apparently has a ring to it. The principal told him that he will need to "tolerate" it. I teach music and feel deeply hurt by this excuse. The kid has trouble with other teachers too and this is not just a problem in my room. What should I do?
