This document provides an overview of a project aimed at identifying best practices for sport for development (S4D) organizations to improve outcomes for children. The research team conducted in-depth case studies of 10 S4D organizations across different regions and program types. By drawing on literature reviews and interviews, the project seeks to determine practices that lead to positive impacts, especially for vulnerable children, in areas like program design, implementation, scaling, and sustainability. The overall goal is to develop an evidence-based guiding framework to help S4D organizations strengthen their work in empowering children through sport.
