CONFERENCE EDITION FOR PUBLICATION EXPECTED OCTOBER 2021. The World Bank's Service Delivery Indicators (SDI) surveys aim to measure the quality of services when the service meets the citizens: in schools and health facilities. Have teachers mastered the subject matter they are teaching, and can doctors accurately diagnose and treat key health conditions? Are schools and health facilities stocked with the needed equipment, supplies, and infrastructure to optimize learning and clinical care outcomes? Are schools and health facilities equipped to provide services during a pandemic? For the past ten years, the World Bank's SDI surveys have collected nationally-representative data across Sub-Saharan Africa to help identify areas of resilience and constraint in service delivery, shedding light on how service delivery may foster or stunt human capital accumulation. The evidence from SDI surveys offers important insights for how countries can build back better in the wake of the massive disruptions brought about by the COVID-19 pandemic.
