The purpose of this study is to review the status of differential item functioning (DIF) research in language testing, particularly as it relates to the investigation of sources (or causes) of DIF, which is a defining characteristic of the third generation DIF. This review included 110 DIF studies of language tests dated from 1985 to 2019. We…

This article discusses a range of current issues and future research possibilities in Communicative Language Testing (CLT) using, as its departure point, the key questions which emerged during the CLT symposium at the 2010 Language Testing Forum. The article begins with a summary of the 2010 symposium discussion in which three main issues related…

In this special issue on high-stakes English language testing in China, the two articles on computer-based testing (Jin & Yan; He & Min) highlight a number of consistent, ongoing challenges and concerns in the development and implementation of the nationwide IB-CET (Internet Based College English Test) and institutional computer-adaptive…

The five studies presented in this special issue offer unique evidence, analyses, and theoretical rationales for assessment tasks that involve writing in reference to information from source material with substantial content. I review the five studies in respect to five "promises" and five "perils," concluding that, collectively, the promises were…

Looking back to the language testing world of the 1980s in the United Kingdom, we need to be aware that how we perceive or remember ourselves to have been then--whether as individual language testing academics or as corporate language testing organisations--will be shaped by multiple influences. Although we may have been present at and shared in…

In 1980 the first meeting of the UK-based Language Testing Forum was held in Lancaster. In 2010, 30 years later, the annual meeting celebrated that first meeting, basing the discussions, as in 1980, on three seminal papers: on the structure of language ability, on communicative language testing, and on testing Languages for Specific Purposes.…

Professor J. Charles Alderson grew up in the town of Burnley, in the North-West of England, and is still based in the North West but in the ancient city of Lancaster. From Burnley to Lancaster, however, lies a journey and a career that took him all around the world to share his knowledge, skills, and experience in language testing and to learn…

This article critiques traditional single-level statistical approaches (e.g., multiple regression analysis) to examining relationships between language test scores and variables in the assessment setting. It highlights the conceptual, methodological, and statistical problems associated with these techniques in dealing with multilevel or nested…

Despite the recent increase of structural equation modeling (SEM) in language testing and learning research and Kunnan's (1998) call for the proper use of SEM to produce useful findings, there seem to be no reviews about how SEM is applied in these areas or about the extent to which the current application accords with appropriate practices. To…

Lyle F. Bachman is Professor, Department of Applied Linguistics, University of California, Los Angeles. He is a past president of the American Association for Applied Linguistics and of the International Language Testing Association. He has published numerous articles and books in the areas of language testing, program evaluation, and second…

The purpose of this article is to reflect on the state of the theorizing and praxis of DIF in general: where it has been; where it is now; and where I think it is, and should, be going. Along the way the major trends in the differential item functioning (DIF) literature are summarized and integrated providing some organizing principles that allow…

This article reviews research on differential item functioning (DIF) in language testing conducted primarily between 1990 and 2005 with an eye toward providing methodological guidelines for developing, conducting, and disseminating research in this area. The article contains a synthesis of 27 studies with respect to five essential sets of…

In this selective look at research on test-taking strategies over the last 25 years, brief mention is made of the beginnings of test-taker strategy research, and then important developments in its evolution to the present are discussed, focusing on conceptual frameworks for classifying strategies, first and second language-related strategies,…
