In any given year, approximately one million children come to the attention of the US child welfare system. Many are victims of abuse or neglect, live with caregivers who are impaired, and/or deal with school and community violence as a fact of life. Identifying these traumas and providing early intervention are crucial to assisting children traumatized by maltreatment and other stressors.
The National Child Traumatic Stress Network (NCTSN) has developed tools and materials for building skills and increasing knowledge about childhood trauma to help child welfare administrators, caseworkers, frontline staff, other mental health personnel, and caregivers understand and respond to the needs of traumatized children.

Helping Children in the Child Welfare System Heal from Trauma: A Systems Integration Approach  (2005) (PDF) 
A report on the results of a survey conducted among child-serving agencies in a number of states. Primary goal of the survey was to understand how various service systems and agencies communicate with each other about trauma in the children they serve. Also identifies the ways agencies may inadvertently be retraumatizing some children, how they promote a child's healing following a traumatic event, and gaps in communication among agencies and systems. Knowledge gained from the survey can inform the development of training and educational materials to breach the gaps and to improve collaboration.
Using Trauma-Informed Child Welfare Practice to Improve Placement Stability: Breakthrough Series Collaborative 
In September 2012, the NCTSN, with funding from SAMHSA, launched a Breakthrough Series Collaborative (BSC) which focused on developing and implementing trauma-informed child welfare practices that would increase the probability that children who need out-of-home placement remain in a single, appropriate and stable home whenever possible. This BSC included nine teams from around the country, each representing a partnership between the public child welfare agency and a mental health agency or organization that provided evidence-based interventions for child trauma to children in foster care. Each team included administrators, supervisors, case workers, clinicians, a birth parent, a foster parent, and, on occasion, youth. These teams worked together from October 2010 through September 2012 to test, implement, and sustain trauma-informed strategies and practices that showed promise in improving placement stability. The following materials describe the results of their work, highlighting the trauma-informed practices they developed and adapted.
