In this article, we reviewed and interpreted the evidence from 223 rigorous impact evaluations of educational initiatives conducted in 56 low- and middle-income countries. We considered for inclusion in our review all studies in recent syntheses that have reached seemingly conflicting conclusions about which interventions improve educational…

Many states have implemented or expanded state-funded prekindergarten programs in the last decade, encouraged by claims about the benefits that can be expected and the importance of early experiences for children's development, especially for economically disadvantaged children.

Prior research evaluating school entry age effects has largely overlooked the effects on social-behavioral skills despite the growing recognition of returns to such skills.

The present study examined the impacts of the Boston Public prekindergarten program-which combined proven language, literacy, and…

Despite increased investment in early childhood care and education (ECCE) globally, little is known about its effectiveness in low-income countries. Using kernel exact matching within a national sample of 1,623 Zambian 6-year-olds, we test the associations between ECCE participation and seven domains of children's school readiness. We find ECCE…
