The BHP Foundation is investing significantly in global education programs and initiatives that are intended to improve the use of evidence to enhance education and learning. In this report, we present a system to evaluate this investment during a fiveyear period. We provide a strategic theory of change, an analysis of challenges and lessons learned through the initiative to date, a framework of indicators to measure progress, an approach to analyze networks in support of better use of evidence in education, and a comparison with other similar foundations or social investment initiatives. Our system offers an evaluation framework for a philanthropic education program, an approach to understanding this program's contribution and place in the broader global education reform movement, and a case study of how this program conceptualizes and measures its own progress. This report will be of interest to the BHP Foundation and its program partners, policymakers engaged in global education, other foundations interested in evaluation models, and academics.This study was undertaken by RAND Education and Labor, a division of the RAND Corporation that conducts research on early childhood through postsecondary education programs, workforce development, and programs and policies affecting workers, entrepreneurship, and financial literacy and decisionmaking. This study was sponsored by the BHP Foundation. The BHP Foundation is committed to improving educational equity for underserved students around the world.More information about RAND can be found at www.rand.org.
