This book introduces edumetrics, a rigorous, interdisciplinary framework for measuring learning outcomes over time and across space. Based on Lord Kelvin's maxim that to measure is to know, edumetrics redefines education as an empirical science that integrates economics, psychology, and social science to quantify cognitive and non-cognitive competencies.

By harmonizing data from over 120 countries spanning half a century, the book transforms fragmented indicators into coherent measures of learning quality and equity. It critiques the limitations of traditional human capital theory and challenges the use of years of schooling as a proxy for skill. Through econometric analysis, historical inquiry, and global datasets, including Learning-Adjusted Years of Schooling, it reveals that educational structures, not just resources, shape productivity, adaptability, and social cohesion.

At its core, the book addresses the paradox of why rising investments in schooling have not yielded proportional gains in learning. With its integration of theory, data, and historical perspective, it serves as both a methodological blueprint and a call to rethink how we define, measure, and value learning in the twenty-first century.

Presents global education trends using the largest dataset on learning outcomes since 1970 Uncovers the hidden costs of educational inequality through rigorous data and counterfactual analysis Measures not just access to schooling, but the actual learning achieved across 120+ countries
