This document discusses the development and implementation of a Behavioral Matrix (BM) for a 4th grade classroom. It identifies 5-8 severe behaviors such as drugs, weapons, vandalism, and bullying and their corresponding administrative responses outlined in the discipline manual. It then presents the BM which lists school-wide expected behaviors and rewards. It also lists 3 levels of offenses and their corrective responses which become increasingly severe, such as warnings, loss of privileges, detention, and suspension. Finally, it emphasizes the importance of the BM being understood by all stakeholders and implemented consistently as part of a school-wide positive behavior support system.
