The document describes the Stages of Escalation model for understanding and responding to escalating problem behaviors. The model outlines seven stages - from calm to trigger, agitation, acceleration, peak, de-escalation, and recovery. For each stage, it provides examples of the behaviors a student may exhibit and recommendations for intervention strategies focused on prevention, redirection, reducing anxiety, ensuring safety, and reestablishing routines. The goal is to identify how and when to intervene early, manipulate environmental factors, and teach replacement behaviors to deescalate problem situations.
