> Teachers who habitually pick nemesis students year after year, to single out for uniquely harsh punishment and public derision. From what I've seen myself and heard from others, it's a serious and widespread problem, and has been for generations.

Keep the ratio of kids to adults low, 6:1 is probably the outer limit. Also the adults should be sane and emotionally mature.
