Middle-school-age children are faced with a variety of developmental tasks, including the beginning phases of individuation from the family, building peer groups, social and emotional transitions, and cognitive shifts associated with the maturation process. This article summarizes how traumatic events impair and complicate these developmental tasks, which can lead to disruptive behaviors in the school setting. Following the call by Walkley and Cox for more attention to be given to trauma-informed schools, this article provides detailed information about the Animating Learning by Integrating and Validating Experience program: a school-based, trauma-informed intervention for middle school students. This public health model uses psychoeducation, cognitive differentiation, and brief stress reduction counseling sessions to facilitate socioemotional development and academic progress. Case examples from the authors' clinical work in the New Haven, Connecticut, urban public school system are provided.
