Early childhood trauma/adverse childhood experience is a widespread problem, with lasting impact for the traumatized child, their community and, ultimately, society. But school can be a place where traumatized children can find safety, consistency and be successful. This starts by understanding how trauma impacts brain development and a child’s ability to learn. Then teachers and school communities can develop a plan for integrating trauma-sensitive routines and supports throughout the school day. Mr. Ristuccia explains how trauma impacts learning and why a whole school approach to becoming trauma sensitive is the most successful strategy for providing the safety, consistency and relational environment for all students to learn emotionally and socially.
