There is growing evidence that children are vulnerable to poor psychological outcomes following exposure to a range of potentially traumatic events. Teachers are in a unique and well-placed position to provide vital support to children following potentially traumatic events and to also provide a vital role in helping to identify children who may be experiencing ongoing psychosocial difficulties. We present a review of mental health trauma resources available for use in educational settings within Australia and New Zealand, with a primary focus on post-disaster resources. We describe the design, development, and dissemination of our resources and training package, Childhood Trauma Reactions: A Guide for Educators from Preschool to Year 12, and present data on how these resources were received. Trauma-informed practices within the school and classroom will enable better outcomes in the immediate post-trauma environment and beyond for all children. Our model focuses on: (1) increasing awareness and understanding of children's post-trauma reactions, (2) exploring effective strategies for teachers within the classroom, and (3) developing policy and procedures for the identification and referral of children who may be at risk. More funding is required to help distribute training and resources and to make mental health following trauma a higher priority.
