And if it's not, the first thing that's must go on the teachers side is her punitive attitude. So she's saying your kids got ADHD, a learning disability, and punishing him by taking away fun things is going to make it better? Would it make sense to her to punish a child in a wheelchair because it might make him walk? A behavioral plan might help him learn better impulse control, but ONLY if it is positive reinforcement - use points to build up to something good. And don't listen to her moaning what about the other kids, who do sit still - that's the point. They can do it, they don't need it. Put up a reward system, points awarded for every minute he does stay in his seat when she, as apparently for some unfathomable reason she keeps doing, leaves her classroom. Just make her award the points to the other kids too, if she feels she needs to, who cares. What he can buy from you with his reward points is not her business. And no taking away points. Just building good habits. You may want to read up on Kazdin method. I never got around to properly using it, but it really helps reframe positive habit building as opposed to the punishment that serves for nothing but selfishly make the authority figure feel better.
