Carol A. Chapelle shows readers how to design validation research for tests of human capacities and performance. Any test that is used to make decisions about people or programs should have undergone extensive research to demonstrate that the scores are actually appropriate for their intended purpose. Argument-Based Validation in Testing and Assessment is intended to help close the gap between theory and practice, by introducing, explaining, and demonstrating how test developers can formulate the overall design for their validation research from an argument-based perspective.

About the Author
Carol A. Chapelle is Distinguished Professor of Liberal Arts and Sciences at Iowa State University, where she teaches courses in second language acquisition and assessment including a course on argument-based validity. She has over 30 years of experience working on research and development in testing and assessment for English as a second language including supervision of Ph.D. dissertation research, participation in test development projects, and advisory service for commercial, non-profit, and government projects in testing. Throughout her research and practice in language testing, she has explored the evolving methodological guidance for conducting validation research. She was led to the nascent concepts of argument-based validation in the early writing of Michael Kane while working on a project to summarize the validation research for the Test of English as a Foreign Language (TOEFL iBTTM). The team cultivated Kane's concepts into a validity argument that succeeded in providing a means for encompassing multiple types of qualitative and quantitative data within a coherent framework showing the connections across test development, test performance and the uses of the scores. The result was a book presenting the validity argument for the TOEFL iBT, Building a Validity Argument for the Test of English as a Foreign Language (Chapelle, Enright, & Jamieson, 2008), which remains a rare example of a validity argument in use for other researchers. She is the recipient of the 2012 Cambridge-International Language Testing Association Lifetime Achievement Award, the 2012 Educational Testing Service TOEFL Program Messick Memorial Lecture Award, and the 2015 Distinguished Scholarship and Service Award from the American Association for Applied Linguistics. She has served as co-editor of the Language Testing (2016-2018), co-editor of the Cambridge Series in Applied Linguistics (2007-present), and founding editor of the Encyclopedia of Applied Linguistics (Wiley-Blackwell, 2012-present).

Reviews
Chapelle's "Argument-Based Validation in Testing and Assessment" is among the best-written texts on test validity. It is an up-to-date, cogent presentation from a logical - as opposed to strictly psychometric - perspective.
-- Shlomo Sawilowsky * Review *
This text address complex philosophical discussions related to validity and reliability in an accessible way. It models a way of thinking about assessment decisions that many of our students need to be successful in their future work!
