Wow--all these systems sound so complicated compared to the system at my kids' school: any infraction (forgotten homework, talking out of turn, misbehavior on the playground, etc.) is punished by THE RED X. Kids who get a "red x" must literally stand on a red x painted at the edge of the playground during recess. The kids on the x's are supervised by a teacher. They are not allowed to talk while on the x. They are allowed to stand, sit, drink water, eat their snack, and be excused to use the bathroom.
Three red x's = A BEHAVIOR TICKET. The student is sent to the vice principal who gives them a talking to and writes out the ticket. The behavior ticket must be brought home, signed by the parents, and returned to the vice principal.
From my observations, some of the teachers overuse the red x to the point that some kids have so many that they never get recess. Of course, at that point, it doesn't matter to those kids at all if they receive another red x. Overall, the system works as a deterent to kids who are generally well behaved. It does nothing to solve real behavior problems, though.
