Rating scale development in the field of language assessment is often considered in dichotomous ways: It is assumed to be guided either by expert intuition or by drawing on performance data. Even though quite a few authors have argued that rating scale development is rarely so easily classifiable, this dyadic view has dominated language testing…

Argument-based validation requires test developers and researchers to specify what is entailed in test interpretation and use. Doing so has been shown to yield advantages (Chapelle, Enright, & Jamieson, 2010), but it also requires an analysis of how the concerns of language testers can be conceptualized in the terms used to construct a…

Construct validity and building validity arguments are some of the main challenges facing the language assessment community. The notion of construct validity and validity arguments arose from research in psychological assessment and developed into the gold standard of validation/validity research in language assessment. At a theoretical level,…

The studies documented in the four articles in this special issue uniquely exemplify principles of design-based research as follows: by taking innovative approaches to significant problems in the contexts of real educational practices; by addressing fundamental pedagogical and policy issues related to language, learning, and teaching; and, in the…

Elicited imitation (EI) has been widely used to examine second language (L2) proficiency and development and was an especially popular method in the 1970s and early 1980s. However, as the field embraced more communicative approaches to both instruction and assessment, the use of EI diminished, and the construct-related validity of EI scores as a…

Research investigating corpora of English learners' language raises new questions about how syntactic complexity is defined theoretically and operationally for second language (L2) writing assessment. I show that syntactic complexity is important in construct definitions and L2 writing rating scales as well as in L2 writing research. I describe…

This paper examines the uptake of Rasch measurement in language testing through a consideration of research published in language testing research journals in the period 1984 to 2009. Following the publication of the first papers on this topic, exploring the potential of the simple Rasch model for the analysis of dichotomous language test data, a…

Educational policies such as Race to the Top in the USA affirm a central role for testing systems in government-driven reform efforts. Such reform policies are often referred to as the global education reform movement (GERM). Changes observed with the GERM style of testing demand socially engaged validity theories that include consequential…

Previous test fairness frameworks have greatly expanded the scope of fairness, but do not provide a means to fully integrate fairness investigations and set priorities. This article proposes an approach to guide practitioners on fairness research and practices. This approach treats fairness as an aspect of validity and conceptualizes it as…

The Assessment of Language Competence (ALC) certificates is an annual, international testing program developed by the Australian Council for Educational Research to test the listening and reading comprehension skills of lower to middle year levels of secondary school. The tests are developed for three levels in French, German, Italian and…

The testing and examination history in China can be traced back to the imperial period nearly two thousand years ago. The existence of English language testing (tests), on the other hand, has a much shorter history. These English tests, developed and administered over the past 20 years, however, are taken by billions of learners of the English…

The present study utilized both the IRT-LR (item response theory likelihood ratio) and a series of CFA (confirmatory factor analysis) multi-sample analyses to systematically examine the relationships between DIF (differential item functioning) and DTF (differential test functioning) with a random sample of 15 000 Korean examinees. Specifically,…

Grammar is central to language description and a "posteriori" construct validation of language tests consistently identifies grammar as a significant factor in differentiating between score levels and characterizing overall proficiency. However, there is currently no model of grammatical competence robust enough to be operationalized in tests.…
