Validity Argument in Language Testing
Case Studies of Validation Research

'This book is both tightly focused on the principles of argument-based language test validation and yet wide-ranging in its attention to different contexts in which validation is undertaken, including the use of technology in test development, delivery, and scoring. After a cogent introduction to the theory of validity argument, each chapter focuses on one or two aspects of the procedure so that by the end, readers have a clear understanding of this complex but highly effective approach to language test validation. Danny Douglas, Professor Emeritus, Applied Linguistics, Iowa State University

'Validity Argument in Language Testing is a much-needed resource for researchers, graduate students, and practitioners learning the intricacies of the argument-based approach to validation in language testing. The highly experienced editors have drawn together a successful combination of theoretical grounding and example studies focusing on various aspects of the approach. The book will be a valuable resource for many generations of language assessors.' Ute Knoch, Director of the Language Testing Research Centre and Associate Professor in Language Assessment, University of Melbourne

'This volume provides important insights into the utility of an argument-based approach to validity. Case studies representing a range of tests, contexts and validation methods provide fertile ground to explore the benefits, and limits, of an argument-based approach. This collection will appeal to anyone keen to learn about the application of validity theory in concrete language testing situations.' Luke Harding, Professor in English Language and Linguistics, Lancaster University
