School safety success is often measured by incidents, crises, or failures. However, effective prevention reduces events — making success harder to demonstrate. Prevention can be revealed by how often escalation or a crisis does not occur. Crises that don’t happen often reflect preparation, not luck. PBIS already tracks the conditions that prevent crises — they’re just not always framed that way in the context of school safety and crisis prevention. This closing webinar will highlight how PBIS makes prevention observable and measurable; measuring what didn’t happen allows schools to lead with evidence, not fear.
