A global cost-effectiveness database for education policies and interventions
Using a common metric: Learning-Adjusted Years of Schooling
What it is
We bring together evidence from over 200 evaluations of education interventions across 52 countries, using a single, comparable measure of learning: Learning Adjusted Years of Schooling (LAYS). This database captures each policy’s impact and its cost-effectiveness. It contributes to closing the global learning gaps by informing on the scalability of these interventions.
This compilation draws on multiple evaluation databases, enriched with studies from the World Bank’s Strategic Impact Evaluation Fund (SIEF) and a major new data collection initiative conducted in collaboration with the Global Education Evidence Advisory Panel (GEEAP). Together, these sources create one of the most comprehensive resources to date of what works – and what works best – in improving education outcomes in low- and middle-income countries.
How it works
Access a database of impact evaluations in education in low and middle-income countries and/or enter your impact evaluation to express impacts in terms of learning-adjusted years of schooling.
Access the database
Express your results in terms of LAYS and add a study to the database

Global Education Evidence Advisory Panel
The LAYS analysis has been used as a critical input into a recent review by the Global Education Evidence Advisory Panel (GEEAP), a new body of global experts co-convened by the World Bank, FCDO, UNICEF, USAID, and BE2, which continually reviews evidence on cost-effective policies and programs. The GEEAP released its first report titled “Cost-Effective Approaches to Improve Learning: what does the evidence tell us are ‘Smart Buys’ for improving learning in low- and middle-income countries?” and has since released multiple rounds of updated reports.
