This latest report from the Brooking Institute demonstrates how countries are grappling with how to scale quality education for their children and youth. Quality education is at the center of a nation’s progress, and it is also enshrined in the United Nations Sustainable Development Goals, which 193 countries have recently committed to support. While the spread of schooling over the past 150 years is one of the most widely successful “going to scale” stories, this expansion too often has been met with little mastery of core academic content and higher-order thinking skills. Millions Learning: Scaling up quality education in developing countries tells the story of where and how quality education has scaled in low- and middle-income countries. The story emerges from wide-ranging research on scaling and learning, including 14 in-depth case studies from around the globe. Ultimately, Millions Learning finds that from the slums of New Delhi to the rainforest in Brazil, transformational change in children’s learning is happening at large scale in many places around the world. We find that successful scaling of quality learning often occurs when new approaches and ideas are allowed to develop and grow on the margins and then spread to reach many more children and youth.
