The most widely used comprehensive assessment system—the Woodcock-Johnson—is separated into two distinct test batteries: Cognitive Abilities (COG) and Achievement (ACH). The WJ III COG includes tests of knowledge, reasoning, memory and retrieval, speed, auditory processing, and visual-spatial thinking. To use these tests properly, professionals need an authoritative source of advice and guidance on how to administer, score, and interpret them. Cowritten by the senior author of the Woodcock-Johnson, Essentials of WJ III Cognitive Abilities Assessment, Second Edition is that source.

Like all the volumes in the Essentials of Psychological Assessment series, this book is designed to help busy mental health professionals, and those in training, quickly acquire the knowledge and skills they need to make optimal use of major psychological assessment instruments. Each concise chapter features numerous callout boxes highlighting key concepts, bulleted points, and extensive illustrative material, as well as test questions that help you gauge and reinforce your grasp of the information covered.

Thoroughly revised and updated with all-new case reports, a brand new clinical applications chapter, and reflective of the latest information available on the WJ III, including the Diagnostic Supplement and the 2007 Normative Update, the Second Edition is the best source for state-of-the-art guidelines to the Cognitive Abilities portion of the WJ III. Offering expert assessment of the test’s relative strengths and weaknesses, this book complements Essentials of WJ III Tests of Achievement Assessment (Wiley).
