My school (secondary) doesn't have a school-wide policy on behaviour, so everyone comes up with their own. I have a system whereby students get a warning the first time they do something they ought not to be, then consequences escalate, until the student is removed. Obviously if the incident is serious, then I remove straight away.
Today on of my Yr 10s said she'd work better if she was allowed to work off her warning, and that most people allow this. I don't want to, I think doing work doesn't excuse the fact someone was talking over me. Plus the subjective nature: does doing 5 questions but getting them all wrong warrant a clean slate compared to doing only two questions but getting them right.
Do you let students work off warnings or consequences? I reward all good things even if they've already earned sanctions as well.
