• Impact evaluation study by the World Bank
• On Save the Children ECD programs in Mozambique
Study shows positive impact for children enrolled in preschool
24% more likely to be enrolled in primary schoolSpent 46% more time on school-related activities

Return on Investing Early
• Reduce disparities and prevent future reading failures.
• Decrease probability of disadvantaged children persistingthrough poverty.
• Increased school readiness.
higher enrollments in primary school
less wastage and repetition of academic years
fewer drop outs
increased impact on learning achievement

D. Current State & Future Possibilities
• Minimal and spotty, especially for children whoare the most disadvantaged, economically,
linguistically and ethnically.
• The OECD estimates a minimum of 1% GNP isneeded to ensure quality ECD services.
•However, many governments appear reluctant tomake the initial investment.
