A former colleague is a principal and she has a problem. She has a student with behavioral issues which include shouting, pushing and non-violent aggression, and in general he interrupts and even halts most of his classes. He also has an IEP and when she met with the parents after one incident, they made clear that their advocacy for him would include litigation should she do almost anything. Over the last two years, around 50 students have left the school citing specifically this student's negative effect on learning and/or fears of potential violence.
