Focused on the interpersonal aspects of internal evaluation in non-profit organisations, this book presents practice-based discussions centred on six key topics identified through the authors’ experience as evaluation practitioners. Internal Evaluation in Non-Profit Organisations: Practitioner Perspectives on Theory, Research, and Practice is not a step-by-step how-to guide; instead, each chapter unpacks an aspect of internal evaluation in non-profits that is paid insufficient heed in the existing literature. Written by and for internal evaluation practitioners, the book contains a plethora of practical strategies and critical analysis of thought-provoking topics that are of particular interest and importance to internal evaluators in non-profit settings. The authors understand the pressures facing practitioners and non-profit organisations and share their insights around improving evaluation’s ability to be efficient, embedded, useful, and meaningful. This book will be of interest to researchers, scholars, and students focusing on non-profit management and will hold specific value for internal evaluators who want to harness their unique and influential position to help organisations achieve their goals. Further, this book is ideal for individuals wanting to think critically about evaluation and improve evaluation utilisation by developing their professional capability, building teamwork skills, using informal everyday data, incorporating theory, and developing fruitful relationships with external evaluators.
