Consequences should be clearly and positively stated. They should be consistently applied. Teachers should only develop consequences with which they are comfortable and willing to enforce. If there are circumstances that involve skipping a level or levels of consequences, students should have a clear understanding of what behaviors would justify moving to a more severe consequence. Teachers should clearly explain what will happen if a student refuses to submit to a consequence.
Ideally, the entire school and all teachers with whom the student interacts will follow the same rules and consequences. Avoid consequences that are inconsequential to the student. The point of consequences is to change problem behavior. If consequences that are consistently applied are not working, it is necessary to develop and try new consequences.
