From the letter:
"Achieving well-being among children and youth who have experienced complex trauma requires tools and practices to identify service needs, an array of effective interventions to meet those needs, and periodic data on outcomes to track whether interventions are effective in helping young people.... Essential components of this approach include functional assessment, trauma screening, mental-health assessment, evidence-based practices and individual outcome measurement."
The report goes on to recommend wraparound as a way of providing a coordinated, multicomponent response:
"The System of Care approach builds meaningful partnerships between families and youth who have or are at risk of serious mental health conditions and community-based providers and supports. Developing an individualized treatment plan and a 'wraparound approach,' the SOC uses evidence-based practices to help children, youth, and families function better at home, in school, and in the community."
