The community-based Early Childhood Education and Development (ECED) program with the Ministry of Education and Culture (MoEC)) aims to reach 738,000 children in 50 districts over five years, providing block grants to communities whose residents decide how best to deliver early childhood services. In an effort to understand whether the program is improving children's development and readiness for primary school, and what factors contribute to effectiveness of ECED services, MoEC is undertaking an impact evaluation that tracks over 6,400 children (ages 1 and 4) for a period of three years. The baseline results summarized here are the first to show relationships between parental education, nutrition, and stimulating learning environments and child developmental outcomes in Indonesia.
