The Handbook of Broader Impacts is an essential resource for researchers, administrators, policymakers, and anyone interested in the societal benefits of research. The volume brings together experts who trace the history of broader impacts as a U.S. National Science Foundation policy, explore its relationship to engaged scholarship, and provide models for institutional infrastructure and support. The book equips readers with tools to build the institutional capacity to advance the societal impacts of research, from developing researcher identities and competencies to navigating promotion and tenure. The Handbook of Broader Impacts explores a wide range of initiatives―open science, science communication, citizen science, informal STEM learning, K–12 partnerships, undergraduate research, teacher development, international collaborations, and more. By blending policy context, practical strategies, and real-world examples, the handbook   spells out the value of broader impacts and demonstrates how research can contribute to direct and meaningful change. “When the National Science Foundation established the Broader Impacts (BI) criterion to give researchers the opportunity to show how their research could provide societal benefits in diverse ways, it was understood to be a challenge for the science community. Twenty-five years of experience with BI, as detailed in this book, have shown that researchers―increasingly with the advice of BI professionals―have shown their creativity in meeting the BI criterion while advancing science, the primary goal of the research.”― Neal Lane , senior fellow in science and technology, Rice University’s Baker Institute for Public Policy, and professor of physics and astronomy emeritus  “The National Science Foundation requires researchers to demonstrate how their work benefits society―but most scientists aren’t trained to do this, and many universities lack the support structures to help. This handbook helps fill that gap. It offers a clear overview of the Broader Impacts criterion, practical strategies and examples, and insights into institutional models that work. At a time when public trust in science is waning, showing the value of research to policymakers and the public is essential. Whether you’re a researcher or an administrator, this guide provides the tools to communicate impact, strengthen proposals, and sustain support for science.”― Tobin Smith , senior vice president for government relations and public policy, Association of American Universities “Engaged scholarship is vital for addressing our most complex societal issues. The impressive array of experts in this volume clearly and compellingly describe the theory and practice of these research strategies. At a pivotal moment for research and society, I’m glad we have this comprehensive volume to guide the way.”― Angela Bednarek , director of scientific advancement, The Pew Charitable Trusts, and cofounder of Impact Funders Forum Laurie A.
