This study applied the Mixed Rasch Model (MRM) to the listening comprehension section of the International English Language Testing System (IELTS) to detect latent class differential item functioning (DIF) by exploring multiple profiles of second/foreign language listeners. Item responses of 462 examinees to an IELTS listening test were subjected…

This study aimed to answer an ongoing validity question related to the use of nonstandard English accents in international tests of English proficiency and associated issues of test fairness. More specifically, we examined (1) the extent to which different or shared English accents had an impact on listeners' performances on the Duolingo listening…

Test de Connaissance du Français (TCF), a French knowledge test for any non-native speakers of French, is an official language exam for the certificate of proficiency in French designed by France Éducation international (FIE) and accredited by le Ministère Français de l'Éducation Nationale, de la Jeunesse et des Sports (French Ministry of National…

This study investigated the differences between the ACTFL Oral Proficiency Interview (OPI) and the ACTFL Oral Proficiency Interview - Computer (OPIc) among Spanish learners at a U.S. university. Participants (N = 154) were randomly assigned to take both tests in a counterbalanced order to mitigate test order effects. Data were analyzed using an…

Construct-irrelevant variance is considered as a major threat to validity which indicates the existence of additional unrelated variables that distort the meaning of test scores and cause the test to be biased. Differential item functioning (DIF) analysis is an important technique in examining the validity and fairness of educational tests.…

This article offers a critical review of the Ministry of Science, Research, and Technology English Proficiency Test (MSRT), a high-stakes exam required for postgraduate graduation, scholarships, and certain employment positions in Iran. Despite its widespread use, the design and implementation of the MSRT raise concerns about its validity and…

Applied linguists have increasingly focused on how the lives of English language teachers and learners are shaped by race and its intersections with other marginalized identities (e.g. Von Esch et al, 2020). Curiously overlooked, however, are the experiences of one particularly stigmatized group in English-majority countries: Muslim women veiled…

I analyzed a corpus of the international English language testing system (IELTS) comprising 256 listening sections (1996-2021). The primary objective of the study was to gain insights into the assumptions made by test designers regarding the real-life contexts that test-takers will encounter. Overall, 15 superordinate topic areas and 300 subtopics…

The principle of fairness in testing traditionally involves an assertion about the absence of bias, or that measurement should be impartial (i.e., not provide an unfair advantage or disadvantage), across groups of test takers. In more general-purposes language testing, a test taker's background knowledge is not typically considered relevant to the…

This study details the development of a local test designed to place university Spanish students (n = 719) into one of the four different course levels and to distinguish between traditional L2 learners and early bilinguals on the basis of their linguistic knowledge, regardless of the variety of Spanish they were exposed to. Early bilinguals…

Although there is abundant evidence for the use of first-language (L1) knowledge by bilinguals when using a second language (L2), investigation into the impact of L1 knowledge in large-scale L2 language assessments and discussion of how such impact may be controlled has received little attention in the language assessment literature. This study…

Given the significance of the test fairness, this study aimed to investigate a reading comprehension test for evidence of differential item functioning (DIF) based on English as a Foreign Language (EFL) learners' gender and their mode of learning (conventional vs. distance learning). To this end, 514 EFL learners were asked to take a 30-item…

The purpose of this study was to examine gender and discipline-based Differential Item Functioning (DIF) and Differential Distractor Functioning (DDF) on the Islamic Azad University English Proficiency Test (IAUEPT). The study evaluated DIF and DDF across genders and disciplines using the Rasch model. To conduct DIF and DDF analysis, the examinees…

The documentation of test takers' achievements has been accomplished through large-scale assessments to find general information about students' language ability. To remove subjectivity, Cognitive Diagnostic Assessment (CDA) has recently played a crucial role in perceiving candidates' latent attribute patterns to find multi-diagnostic information…

The redesigned "TOEIC Bridge"® tests were designed to evaluate test takers' English listening, reading, speaking, and writing skills in the context of everyday adult life. In this paper, we summarize the initial validity argument that supports the use of test scores for the purpose of selection, placement, and evaluation of a test…
