Have you ever noticed that the more stringent a behaviour policy is, the worse the actual behaviour tends to be? Have you noticed schools which have a merit / rewards system tend to have worse behaviour? Have you noticed that some schools are very inconsistent and the students do not actually know what they'll achieve through the convoluted merit system? Is anything obtained from putting a child into detention three evenings a week? If they keep attending detention but also keep reoffending, then is there not a bigger problem here? I am feeling that in a post primary setting, there should not be the need for merits / demerits. A school should try to create an atmosphere of mutual trust and leave the starcharts in the primary school. From experience of various schools, when a school has no sense of pride then the students will act up and will keep acting up regardless of how strict the system may be. Behaviour and how to deal with it should be left down to the class teacher rather than having a draconian policy in place throughout the entire school as behaviour is completely relative to the time of day, personal lives and what has gone on before your lesson.
