This report presents an analysis of the Early Childhood Development (ECD) programs and policies that affect young children in Tanzania. This report is part of a series of reports prepared by the World Bank using the Systems Approach for Better Education Results (SABER)-ECD framework and includes analysis of early learning, health, nutrition and social and child protection policies and interventions in Tanzania, along with regional and international comparisons. Tanzania is home to 7.6 million children age 0-6. Child and infant mortality have declined significantly in the last decade. SABER-ECD collects, analyzes and disseminates comprehensive information on ECD policies around the world. In each participating country, multi-sectoral information is collected on ECD policies and programs through a desk review of available government documents, data and literature, and extensive interviews with a range of ECD stakeholders, including government officials, service providers, civil society, development partners and scholars. The SABER-ECD framework presents a holistic and integrated assessment of how the overall policy environment in a country affects young children's development. SABER-ECD identifies three core policy goals that countries should address to ensure optimal ECD outcomes: establishing an enabling environment, implementing widely and monitoring and assuring quality. Improving ECD requires an integrated approach to address all three goals.
