Book excerpt: This book offers a roadmap for developing, growing, and sustaining living-learning communities (LLCs) that promote student success and enhance the undergraduate experience. Drawing on the Best Practices Model presented in Living-Learning Communities That Work, as well as updated research and rich, real-life examples from LLC administrators, the authors offer a revised and improved model for effective LLC practice. Nuanced typologies guide stakeholders in developing and growing their own programs, from the foundational, to the intermediate, and to the advanced level. This text features an extended section on the assessment of LLCs, complete with a logic model for integrating program assessment with student learning outcomes, and concludes with lessons learned from the COVID-19 pandemic and a look into the future of LLCs in higher education. At a time when colleges and universities struggle to create community for students, this book will be a valuable resource to practitioners, researchers, and institutional leaders to more effectively allocate resources to create and sustain LLCs and to realize the potential of these communities to improve undergraduate education.
