This Policy Research Working Paper 10763 discusses the importance of ensuring equal access to early childhood education for all Pakistani children. The paper estimates the cost of expanding access to early childhood education using an adapted version of the early childhood education Accelerator Costing and Simulation model. The cost estimates are presented for three packages: (i) a business-as-usual scenario, (ii) a scenario that includes universal coverage for all children, and (iii) a scenario that includes coverage for all children in underserved areas. The paper highlights the long-term implications of early childhood education for school readiness, workforce participation, and economic growth. The findings of this paper can be used to inform policy decisions and resource allocation for early childhood education in Pakistan.
