These case studies share learning from the strategies and approaches that CRS uses to engage governments. It dives deeper into program application on the concepts of Engaging Government: A CRS Guide to Working for Social Change, with which it was co-developed by the colleagues noted in the acknowledgements of that resource. Taken together, the case studies in this volume have been selected to promote more systematic government engagement for greater influence and impact. The introductory essay, co-written by Scott LeFevre, CRS Director for Health and Social Services, and Dr. David Cortright of the University of Notre Dame Keough School of Global Affairs’, draws out the promising practices and lessons from the case studies and grounds them in the latest academic research.
