The purpose of the GRYD Research Brief Series is to capture GRYD programmatic experiences and research findings in a way that is straight-forward and translatable to others working in this area. The inaugural brief lays the foundation for future briefs by outlining the GRYD Comprehensive Strategy and its related programming. Forthcoming briefs in this series will summarize findings related to a research question or a GRYD-sponsored initiative, highlight the lessons learned, and apply those lessons to practice and policy recommendations.

The pupose of each brief and a summary of findings are presented in the document: An Overview of GRYD Research & Evaluation. Click here to learn more. Full briefs are listed below.
