This critical volume combines theoretical and empirical work across disciplines to explore what threatens scalability—and what enables it—in the early childhood field. Authors and editors provide specific recommendations to help professionals refine and apply the science of scaling in their programs, research, and decision making.

Written by leading experts in early childhood, economics, psychology, public health, philanthropy, and more, chapters and commentaries shine light on how to effectively use experimental insights for policy purposes. The result is a comprehensive and forward-thinking guide to the challenges and possibilities of effective scaling in early childhood and beyond.

Essential reading for researchers, practitioners, funders, and policy makers alike, this book raises vital questions and provides a vision for the long-term journey to scalable evidence.
