Language assessment is increasingly computermediated. This development presents opportunities with new task formats and equally a need for renewed scrutiny of established conventions. Recent recommendations to increase integrated skills assessment in lecture comprehension tests is premised on empirical research that demonstrates enhanced construct…

The International English Language Testing System (IELTS) has served as one of the most reliable proofs of people's English language proficiency. There have been rumors about the discrepancy in difficulty between the two modules of IELTS, namely Academic (AC) and General Training (GT); however, there is little empirical evidence to confirm such a…

This paper discusses the challenges of defining coherence in the context of oral language assessment literacy and proposes that better understanding of the construct can be achieved through a systemic-functional linguistic lens. Coherence is taken to be a foundational quality of written and spoken discourse and is a standard feature in the…

Several high-stakes English proficiency tests including but not limited to IELTS, PTE Academic, and TOEFL iBT recommend a 2-year time limit on validity for score usage. Although this timeframe provides a useful rule-of-thumb for the recency of testing, it can have far-reaching consequences. In response to stakeholder queries around IELTS validity…

The International English Language Testing System (IELTS) is a high-stakes exam where Writing Task 2 significantly influences the overall scores, requiring reliable evaluation. While trained human raters perform this task, concerns about subjectivity and inconsistency have led to growing interest in artificial intelligence (AI)-based assessment…

Cognitive diagnostic models (CDMs) have received much interest within the field of language testing over the last decade due to their great potential to provide diagnostic feedback to all stakeholders and ultimately improve language teaching and learning. A large number of studies have demonstrated the application of CDMs on advanced large-scale…

A critical component of cognitive diagnostic models (CDMs) is a Q-matrix that stipulates associations between items of a test and their required attributes. The present study aims to develop and empirically validate a Q-matrix for the listening comprehension section of the International English Language Testing System (IELTS). To this end, a…

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…

Corpus-based studies have offered the domain definition inference for test developers. Yet, corpus-based studies on temporal fluency measures (e.g., speech rate) have been limited, especially in the context of academic lecture settings. This made it difficult for test developers to sample representative fluency features to create authentic…

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 explores the impact of sociocultural theory-based instruction on enhancing L2 learners' writing skills including grammatical accuracy, coherence, cohesion, task response, and lexical resources for the IELTS. To this end, a cohort of 40 participants, spanning intermediate and advanced proficiency levels, was divided into experimental and…

Applicants must often demonstrate adequate English proficiency when applying to postsecondary institutions by taking an English language proficiency test, such as the TOEFL iBT, IELTS Academic, or Duolingo English Test (DET). Concordance tables aim to provide equivalent scores across multiple assessments, helping admissions officers to make fair…

The measurement of test-taking strategies and practices, mostly studied through qualitative methods, has been an important aspect of language testing and assessment research. The current study examines the test-taking strategies of International English Language Testing System (IELTS) test-takers and reports the process of designing and validating…

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…

Comparing language tests and test preparation materials holds important implications for the latter's validity and reliability. However, not enough studies compare such materials across a wide range of indices. Therefore, this study investigated the text complexity of IELTS academic reading tests (IRT) and IELTS reading practice tests (IRPrT).…
