The framework of developmental assets posits a theoretically-based and research-grounded set of opportunities, experiences, and supports that are related to promoting school success, reducing risk behaviors, and increasing socially-valued outcomes including prosocial behavior, leadership, and resilience. A considerable body of literature on developmental assets has emerged in the last two decades, informing research and practice in education, social work, youth development, counseling, prevention, and community psychology. In addition to synthesizing this literature, this chapter discusses: the recent development of the Developmental Asset Profile, an instrument designed, in part, to assess change-over-time; the utilization of asset measures in international research; the expansion of the assets framework to early childhood and young adults; and new research using latent class analysis (LCA) to identify classes or subgroups of youth.
