During this exploratory session, participants will learn how the brain is impacted by trauma and toxic stress and how these elements manifest in school environments. This awareness and reflection will then be applied to an understanding of the relationships between trauma sensitivity and multitiered systems of support. Discussion and implications for taking steps towards a comprehensive and universal approach to trauma sensitivity will follow along with time for planning the next steps. By the end of the session, participants will define and identify trauma and its types in a broad and inclusive way, illustrate and explain how the brain and body respond to stress and trauma, recognize and compare the impact of trauma on students, parents, school staff and the school environment, apply trauma knowledge to trauma sensitivity and multitiered systems of support.
