The Coalition for Juvenile Justice (CJJ) released this guide to provide practical support to state advisory groups (SAGs) in their efforts to achieve meaningful, authentic engagement with young people who have experienced the justice system. The guide includes actions for SAGs no matter their existing level of youth engagement, whether they've struggled to meet the basic requirements of youth engagement for years or are looking for new ways to deepen already existing youth partnerships. Each stage of youth engagement — recruitment, onboarding and retention — is divided into 101 (introductory), 201 (intermediate) and 301 (advanced) levels of engagement to help SAGs to honestly self-assess their existing practices and readiness for authentic youth engagement and start taking steps from wherever they are.
