Chapter 16 Schools Teachers and Education Outcomes in Developing Countries About 80% of the worlds children live in developing countries. Their well being as adults depends heavily on the education they receive. School enrollment rates have increased dramatically in developing counties since 1960 but many children still leave school at a young age and often learn little while in school. This chapter reviews recent research on the impact of education and other policies on the quantity and quality of education obtained by children in developing countries. The policies considered include not only provision of basic inputs but also policies that change the way that schools are organized. While much has been learned about how to raise enrollment rates less is known about how to increase learning. Randomized studies offer the most promise for understanding the impact of policies on learning.
