In sociolinguistic contexts where standardized languages coexist with regional dialects, the study of differential item functioning is a valuable tool for examining certain linguistic uses or varieties as threats to score validity. From an ecological perspective, this paper describes three stages in the study of differential item functioning…

This quasi-experimental study examines the impact of a diagnosis-based pedagogical intervention on the development of micro English as a foreign language (EFL) reading abilities over time. Specifically, 105 first-year graduate students in a Chinese university completed three diagnostic reading assessments at the beginning, middle, and end of a…

The Korean College Scholastic Ability Test (CSAT) aims to assess Korean high school students' scholastic ability required for college readiness. As a high-stakes test, the examination serves as a pivotal hurdle for university admission and exerts a strong washback effect on the educational system in Korea. The present study set out to investigate…

The interaction between language proficiency and discipline-related background knowledge is an important feature of LSAP (Languages for Specific Academic Purposes) tests and is viewed as a necessity in these tests unlike general purpose language tests which try to diminish the potential effect of discipline-related knowledge. Therefore, variables…

One of the challenges of developing assessments for young language learners is the shortage of evidence-based information about such assessments for languages other than English. In light of this situation, this paper discusses the development of an assessment for young languages learners in the context of Japanese as a second language (JSL). In…

This study examines the relationships among various major factors that may affect the difficulty level of language tests in an attempt to enhance the robustness of item difficulty estimation, which constitutes a crucial factor ensuring the equivalency of high-stakes tests. The observed difficulties of the reading and listening sections of two EFL…

The use of integrated tasks to test English-speaking skills raises questions about the impact of comprehension on test score outcomes, and the impact of stimulus materials on test-taker strategic behaviours. This study analysed speaking performances and verbal report data to examine the strategies used by test takers at different levels of…

Reading comprehension is based on the efficient accomplishment of several cognitive processes at the word, sentence, and text level. To the extent that each of these processes contributes to reading comprehension, it can cause reading difficulties if it is deficient. To identify individual sources of reading difficulties, tools are required that…

The study reported here investigates the validity of judgments made when aligning tests to the "Common European Framework of Reference" (CEFR). Listening tests operationalizing pre-defined difficulty-determining characteristics were to be aligned to CEFR levels. We employed a modified version of the item-descriptor-matching-method. Ten…

The first aim of this study was to develop a computer adaptive EFL test (CALT) that assesses test takers' listening and reading proficiency in English with dichotomous items and polytomous testlets. We reported in detail on the development of the CALT, including item banking, determination of suitable item response theory (IRT) models for item…

The present study examined the factor structures across features of 446 examinees' responses to a writing task that integrates reading and listening modalities as well as reading and listening comprehension items of the TOEFL iBT[R] (Internet-based test). Both human and automated scores obtained for the integrated essays were utilized. Based on a…

Integrated reading/writing tasks are becoming more common in large-scale language tests. Much of the research on these tasks has focused on writing through reading; assessing reading through writing is a less explored area. In this article we describe a reading-into-writing task that is intended to measure both reading comprehension and language…

The present study investigated the functioning of three psychometric models for cognitive diagnosis--the general diagnostic model, the fusion model, and latent class analysis--when applied to large-scale English as a second language listening and reading comprehension assessments. Data used in this study were scored item responses and incidence…

In researching the potential of cognitive diagnostic assessment, researchers concur that the quality of diagnostic inferences is subject to the extent to which the construct representations based on cognitive skills are theoretically compelling, empirically sound, and relevant to test use. In this paper, I argue that the construction of a Q matrix…

Since 2000, the General English Proficiency Test, a newly developed test of English, has been phased in by the Language Training and Testing Center in Taiwan. It has become the most universally used test of English in Taiwan, a fact that can be evidenced by its aggregate number of registered test takers. This article first describes the…
