Early childhood development outcomes play an important role throughout a person s life, affecting one s income-earning capacity and productivity, longevity, health, and cognitive ability. The deleterious effects of poor early childhood development outcomes can be long-lasting, affecting school attainment, employment, wages, criminality, and social integration of adults. The authors first take stock of early childhood development indicators in the region and explore access to early childhood development services for children of different backgrounds. They review recent evidence on the impact of early childhood development interventions in the region and investigate more deeply a selection of programs in Latin America and the Caribbean to distill lessons related to their design, implementation and institutionalization processes. The book concludes with a discussion of the challenges of scaling up and presents policy options to develop national early childhood development policies and programs that may be effective and sustained over time.
