Where are you basing this on? In public schools in the US (at least in my hometown in Louisiana), schoolteachers don't get assistants of any sort. You get the occasional "student teacher," who is training to become a schoolteacher, but never more than one.
Faculty at colleges get teaching assistants, but their job is hardly to help with conflicts or prevent violence, their job is to help with instruction, grading, writing homework assignments, etc. When I was a teaching assistant, I myself tended to have 10-20 students in my section, and the class as a whole had close to a hundred people.
