The National Center on Family Homelessness at the American Institutes for Research has led the nation in developing and disseminating knowledge about trauma and violence and addressing its effects on homeless families for more than 20 years. As a member of the National Child Traumatic Stress Network from 2003 to 2007, the National Center and its partners formed the National Collaborative for Trauma-Surviving Homeless Children to address the unmet trauma-related needs of homeless children and their parents. The National Center has developed a Trauma-Informed Organizational Curriculum for use in homeless service settings, settings serving women, veterans, and children, and organizations serving displaced populations. The central component of the curriculum is a Trauma-Informed Organizational Self-Assessment that includes concrete practices or benchmarks of trauma-informed care for special populations, and serves as a guide for agencies to begin the process of adopting a trauma-informed approach agency-wide. The National Center provides training and technical assistance on traumatic stress, trauma-informed care, and secondary traumatic stress and self-care both locally and nationally, and provides individualized consultation to support organizations in implementing a trauma-informed service model.
