Book excerpt: First published in 1994, this text is designed to be used by graduate-level social work students in courses on evaluation and program design. Over the course of 20 years and 6 editions, the goals of the book have remained the same: to prepare students to participate in evaluative activities within their organizations; to prepare students to become critical producers and consumers of professional evaluative literature; and to prepare students for more advanced evaluation courses and texts. Grinnell, Gabor, and Unrau aim to meet these objectives by presenting a unique approach that is realistic, practical, applied, and user-friendly. While a majority of textbooks focus on program-level evaluation, some recent books present case-level evaluation methods but rely on inferentially powerful -- but difficult-to-implement -- experimental baseline designs. This text assumes that neither of these approaches adequately reflects the realities of the field or the needs of students and beginning practitioners. Instead, Program Evaluation for Social Workers offers a blend of the two that demonstrates how they can complement one another. The integration of case-level and program-level approaches provides an accessible, adaptable, and realistic framework for students to more easily grasp and implement in the real-world.
