This paper presents a model to guide capacity-building in state public education systems for delivery of evidence-based family and youth interventions—interventions that are designed to bolster youth competencies, learning, and positive development overall. Central to this effort is a linking capacity agents framework that builds upon longstanding state public education infrastructures, and a partnership model called PROSPER or PROmoting School–community–university Partnerships to Enhance Resilience. The paper presents an overview of the evolving partnership model and summarizes positive results of its implementation over a 12-year period in an ongoing project.
