Over thirty years of input from instructors and students have gone into this popular research methods text, resulting in a refined ninth edition that is easier to read, understand, and apply than ever before.

By integrating both evaluation and research methods and assuming no previous knowledge of research, this book makes an excellent reference for professionals working in social work and health settings who are now being called upon to conduct or supervise program evaluation and may need a refresher on research methods.

An eminently approachable and practical introduction to case- and program-level evaluation techniques.
