The National Child Traumatic Stress Network (NCTSN) was created by Congress in 2000 as part of the Children’s Health Act to raise the standard of care and increase access to services for children and families who experience or witness traumatic events. This unique network of frontline providers, family members, researchers, and national partners is committed to changing the course of children’s lives by improving their care and moving scientific gains quickly into practice across the U.S. The NCTSN is administered by the Substance Abuse and Mental Health Services Administration (SAMHSA) and coordinated by the UCLA-Duke University National Center for Child Traumatic Stress (NCCTS), which guides NCTSN collaborative efforts. The NCTSN has grown from 17 funded centers in 2001 to 82 currently funded centers and over 130 affiliate (formerly funded) centers and individuals, working in hospitals, universities, and community based programs in 45 states and the District of Columbia.
