This report considers the science of adult literacy acquisition, with the goal of identifying principles that may improve the effectiveness of adult literacy programs. We define literacy as a continuum, from emerging literacy, through improving literacy, to fluent literacy and we outline the...

It is imperative that students learn to read in the early grades, yet many fail to do so in developing countries. Early grade reading interventions have emerged as a common means to attempt to address this problem. This paper presents a definition of early grade reading interventions as...

The gender gap reversal in educational attainment is ubiquitous in high-income countries, as well as in a growing share of low- and middle-income countries. To account for the reversal, this paper proposes a theoretical framework in which the interplay between the distributions of academic...

Students in low-income countries often have trouble learning to read; 80-90 percent of second and third graders in some countries cannot even read a single word and may know few if any letters (RTI 2009, 2010, 2011a, 2011b). The reasons are linked to limited instructional time, textbooks or...

Early grade literacy skills are crucial for children's future education and ultimately their contribution to human capital formation and economic development. A significant challenge in development is identifying low-cost interventions to improve early literacy skills in contexts characterized...

Very few studies currently exist on the long-term impacts of schooling policies in developing countries. This paper examines the impacts-half a century later-of a mass education program conducted by the Democratic Republic of Vietnam in the occupied areas during the First Indochina War....

Worldwide, approximately 781 million adults are unable to read or write in any language. While adult literacy rates have increased significantly over the past several decades, recent progress largely reflects a more-educated younger generation replacing a less-education older generation. The...

A field experiment in rural Liberia is used to study democratic participation in fragile states. Fragile states are marked by political fragmentation, local patronage systems, and voter vulnerability. To understand the effects of such conditions on democratic expression through elections, the...

This report presents available evidence on adult education and training in Europe and Central Asia (ECA), differentiating two separate types: continuing vocational education and training (CVET) for the employed, sought either by employers or individuals, and retraining and second chance...

Working with the Mexican Ministry of Education, this study piloted a scalable program to reduce high school dropout rates by focusing on socio-emotional skill development and mathematics tutoring. The intervention was evaluated through a randomized field experiment with more than 5,000 youths at...
