The Tennessee Network of Trauma-Informed and Evidence-Based Systems (TN-TIES) project will increase access and improve services to youth in foster care who have experienced trauma. Evidence-based, trauma-informed interventions will be disseminated into multiple systems commonly responsible for the care of youth in state custody including resource parents, child welfare staff, and mental health providers. Training will be provided to: 1) 225 resource parents using the curriculum Caring for Children Who Have Experienced Trauma: A Workshop for Resource Parents; 2) at least 60 child welfare workers using the Child Welfare Trauma Training Toolkit; and 3) 50 mental health clinicians using Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) by certified TF-CBT trainers.
