"This remarkable book provides a comprehensive guide to assessment of individuals on the spectrum, across the continuum of development. The extensively updated second edition includes a detailed overview of DSM-5 diagnostic criteria and their application. Much more than an inventory of measurement tools (although for the interested reader, the full range of relevant measures are reviewed in exquisite detail), the book explores both the art and science of using psychometric assessment to understand the diversity of abilities and needs of individuals on the spectrum. The contributors also offer rich insights about intervention in clinical and educational settings and address such important contemporary issues as the cognitive potential of minimally verbal individuals and the importance of understanding sex differences. A vital, in-depth reference for anyone involved in assessing ASD and its complex comorbidities."--Lonnie Zwaigenbaum, MD, Division Director, Developmental Pediatrics; Professor, Department of Pediatrics; and Stollery Children's Hospital Foundation Chair in Autism, University of Alberta, Canada

"If there is one constant in the field of autism, it is the state of flux. Diagnosis, assessment, and treatment are all areas where professionals in the field must work to keep up to date with the science. This timely second edition is a 'must have' for serious autism researchers as well as all professionals and advanced students involved in diagnosis and assessment. It includes well-chosen chapter topics, in-depth coverage of major issues and techniques, helpful case studies, and even a chapter on the pesky pseudoscience that dogs the field. Discussions of historic and future directions provide a nice context for the current state of the art."--Laura Schreibman, PhD, Distinguished Professor Emeritus and Research Professor, Department of Psychology, University of California, San Diego

"Goldstein and Ozonoff have assembled an excellent compendium of cutting-edge information on assessment of people with ASD. Each chapter contributes a layer of knowledge applicable to basic and complex assessment issues. I will definitely keep this volume close at hand for my own clinical practice and as an essential training guide."--Catherine E. Rice, PhD, Professor of Psychiatry and Behavioral Sciences and Director, Emory Autism Center, Emory University School of Medicine -
