Resiliency describes the quality found in some children who, despite the socioeconomic, family, and environmental stresses in their life, are able to avoid the school failure, substance abuse, delinquency, and mental health problems they are at high risk of experiencing. This paper summarizes key concepts from the growing literature on collaboration, and shows how collaborators are being challenged to improve service delivery, engage youth as resources, strengthen families, and empower communities. Resiliency-based collaboration enables service providers to meet those challenges and to protect children and adolescents from yielding to high-risk behaviors. Some of the tools, models, and programs that can be used to promote resiliency in the lives of children and youth are explored. 25 references and 1 appendix
