The Erwin Montessori School implemented a discipline change using the Redirecting Children's Behavior (RCB) approach to develop students' life skills and responsibility. The leadership team led the change process by providing RCB workshops for faculty and parents. They monitored the implementation and evaluated the results. Initially, some faculty resisted the change due to concerns it was not sustainable or would reduce their status. The leadership team addressed resistance through additional training, examples, and accountability. They determined the change process was successful because it maintained a clear vision and plan, improved communication, and engaged faculty. Moving forward, the school aims to fully integrate the new disciplinary approach into its culture.
