This document provides guidance on developing effective classroom rules within a Positive Behavior Interventions and Supports (PBIS) framework. It recommends that rules be positive, specific, observable, applicable throughout class, and posted prominently. Rules should address the most common misbehaviors and there should be no more than 6 rules. Guidelines are also distinguished from rules - guidelines are broader attitudes and traits while rules define specific expected behaviors. Classroom rules should be linked to and support any school-wide guidelines for success.
