This guide is intended to support states, systems, and organizations in their efforts to integrate the Wraparound care coordination process with the Child and Adolescent Needs and Strengths (CANS) decision-making measurement tool. The National Wraparound Initiative (NWI) and the National Wraparound Implementation Center developed this document with Chapin Hall at the University of Chicago, which is the organizational home of the CANS. NWI defines Wraparound as a service delivery strategy that provides comprehensive, holistic, youth and family-driven ways of responding when children and youth experience serious mental health or behavioral challenges. This guide describes how to best use the CANS within the four phases of the Wraparound process: engagement phase, planning phase, implementation phase, and the transition phase.
