The first textbook to emphasize the importance of critical thinking skills to practice, this third edition of the classic retains its unique focus on thinking critically about decisions that social workers make daily. Organized around the phases of helping, this hands-on introduction highlights the decision points that social workers encounter during assessment, intervention, and evaluation. This text, together with its companion website, provides students with a wealth of hands-on exercises for developing and assessing their practice skills. Most importantly, it helps students enhance client well-being by becoming critical thinkers and evidence-informed practitioners.
