Addressing the surge in mental health and social and emotional needs of students and staff will be critical in the upcoming years. The increased understanding of the prevalence of adverse childhood experiences (ACEs) and trauma, and their negative effects on the social, emotional, and academic success of students, has propelled a growing number of schools, districts, and states to explore ways to implement trauma-informed (TI) approaches. With the goal of creating learning environments that are responsive to all students, but especially to the needs of trauma-exposed children and youth, the implementation of TI approaches is getting to be recognized as an effective practice and systems-change strategy toward achieving the goal of educational equity. This resource brief provides information on the principles and components of TI approaches, as well as guidance for initial steps of implementation for schools, districts, and states, in an effort to improve social, emotional, and academic outcomes for students. Resource links containing more details on TI implementation are provided throughout the brief as well as at the end.
