This brief from the U.S. Child Welfare Capacity Building Collaborative outlines the Collaborative’s efforts to support child welfare jurisdictions in integrating the voices of those directly affected by the child welfare system into practice and evaluation. The brief discusses the Collaborative’s approach, which involves qualitative methods like literature reviews and facilitated discussions to understand challenges and successful strategies for incorporating LE into capacity-building efforts. It emphasizes the importance of developing clear definitions and frameworks for LE to ensure meaningful involvement across different jurisdictions and how incorporating LE into child welfare initiatives can lead to better family engagement, more effective services, and improved outcomes for children and families.
