Questions like these often arise in schools when the topic of student behavior comes up. People often disagree on how involved the school should be in teaching behavior, or on how much responsibility the family should assume, or on the best ways to influence and change student behavior.
Every parent knows that a consistent stance is essential to produce a well-behaved child.
This principle is true in schools as well. While some disagreement is probably unavoidable, and even healthy, vast differences in beliefs among the adults in the school will lead to an inconsistent student behavior system that is applied in very different ways from teacher to teacher and team to team. Invariably, this results in a behavior system that is seen by teachers, students and parents as capricious, ineffective and unfair. In order to develop effective student behavior plans, everyone involved must agree on the fundamental beliefs that will drive the behavior code and system. If teachers disagree, the system will be inconsistent.
