This report presents findings from the Learning Community Model for Implementation, a project of the McSilver Institute for Poverty Policy and Research at New York University Silver School of Social Work, in partnership with the National Council for Behavioral Health, to develop a promising methodology to help service organizations adopt and sustain the practices and principles of Trauma-Informed Care (TIC). The Learning Community enrolled 32 behavioral health organizations to determine their readiness to meet the seven TIC domains (listed in this report). By the end of the yearlong project, 92 percent of the participating organizations had implemented TIC in at least six of the seven domains. The authors define the TIC approach as well as the prevalence and effects of trauma, including Adverse Childhood Experiences (ACEs).
