The Fourth Edition of this text offers a clear and direct introduction to the basics of psychological testing as well as to psychometrics and statistics relevant for students new to the field. The authors focus on relating core psychological testing concepts to practical situations that students will recognize, relate to, and find interesting. They provide a variety of pedagogical tools to promote student understanding of the underlying concepts required to effectively use tests and test scores. Primarily concerned with preparing students to become informed consumers and users of tests, the text also features three final chapters focusing on how tests are utilized in three important settings: education, clinical and counseling practice, and organizations.
