Unfortunately, the other kids variable is something that you can only control by moving away. I had to do that in the east bay, California, when the schools started taking more inner-county transfers and running busses. The greatschools score went from ~7.5 to 4 in 2 years. The test scores plunged and they pulled money from the school because it wasn't performing. Like that helps. You can try to work with the school, the teacher, the principal, but you can't really work with the other parents. I can't even imagine how you'd begin that conversation. "Hey, little Johnny acts like a complete asshole and disrupts the class to the point that they are spending their heads down on their desk for half an hour a day. Can you step up and do something about his behavior?" Obviously I'm never going to be a politician, but how can that ever be phrased in a neutral way?!
