This report presents an analysis of the Early Childhood Development (ECD) programs and policies which affect young children in the Kingdom of Tonga. 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 the Kingdom of Tonga and regional and international comparisons. Tonga is a lower-middle-income country with a population of 104,509, of which approximately 13 percent are below the age of 5. SABER-ECD collects, analyzes and disseminates comprehensive information on ECD policies around the world. In each participating country, extensive multi-sectoral information is collected on ECD policies and programs through a desk review of available government documents, data and literature, and 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.
