‘This book deserves a place on the bookshelf of everyone engaged in evaluation- evaluators, evaluation managers, evaluation educators and evaluation researchers. It provides comprehensive and up to date coverage of key concepts and practices in evaluation, such as evaluation use, evaluative thinking, values in evaluation, using theories of change, mixed methods, experimental designs, engagement and participation. It also provides a useful introduction to applications, methods and concepts that might be less familiar such as principles-based evaluation, equitable evaluation, real-time evaluation, futures thinking and big data. The distinguishing feature of the book is the clear and thorough coverage of the issues, providing an overview of its key concepts, development over time and variations, as well as the personal insights from the experienced and informed authors of each chapter. Reading through each chapter feels like being in a masterclass on the topic.’
