Validity is a clear, substantive introduction to the two most fundamental aspects of defensible testing practice: understanding test score meaning and justifying test score use. Driven by evidence-based and consensus-grounded measurement theory, principles, and terminology, this book addresses the most common questions of applied validation, the quality of test information, and the usefulness of test results. Concise yet comprehensive, this volume’s integrated framework is ideal for graduate courses on assessment, testing, psychometrics, and research methods as well as for credentialing organizations, licensure and certification entities, education agencies, and test publishers.

"The book contains a wide range of practical examples of various potential concerns surrounding the validity of a wide range of assessment tools and mechanisms. As a result, it is not just a theoretical analysis of the subject but also a practical guide to anyone embarking on research. Each chapter ends with a brief summary and a statement of the conclusions... it is an important contribution to the literature and I would suggest it will prove invaluable to all those embarking on initial training, doctoral studies or post qualification research." - Jeremy Swinson, Educational Psychology in Practice
