This text investigates the integration of program theory with evaluation science to improve the effectiveness and accountability of social programs. Stewart I. Donaldson, a prominent scholar in the field of evaluation, draws upon decades of research to argue that rigorous evaluation must be grounded in explicit theories of change. He presents a comprehensive framework that bridges the gap between academic research and practical application in real-world settings. The book provides a systematic approach for evaluators to design, implement, and interpret studies that inform policy and practice.

Experts in the field of evaluation recognize this work as a foundational text for understanding the intersection of social science and program management. Readers frequently note the academic density of the prose, which serves as a rigorous guide for graduate students and professional evaluators alike.
