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…

Chinese learners of English often experience difficulty with English tense presumably because their native language is tenseless. We showed that this difficulty relates to their incomplete conceptual representations for tense rather than their poor grammatical rule knowledge. Participants made acceptability judgments on sentences describing…

Incremental intelligence plays an important role in self-regulating and enhancing writing performance among language learners. The present study aimed to investigate the relationship among variables of the incremental theory of intelligence, self-regulatory writing strategies, implicit theory of writing, and writing performance in EFL learners. To…

This study considers language proficiency test scores achieved by ESL students who subsequently entered a New Zealand university at the undergraduate level. Scores from IELTS and the university's in-house English Proficiency Test are analysed to determine the predictive ability of overall scores on these two tests and scores for each of the four…

This paper explores what the measures of utterance fluency typically employed in Automatic Speech Evaluation (ASE), i.e. automated speaking assessments, tell us about oral proficiency. 60 Chinese learners of English completed the second part of the speaking section of IELTS and six tasks designed to measure the linguistic knowledge and processing…

The current study investigates whether vocabulary breadth, vocabulary depth, and vocabulary fluency contribute differentially to L2 reading and listening comprehension. One hundred and thirty-eight EFL learners first took three vocabulary knowledge tests that measured vocabulary fluency, vocabulary breadth, and vocabulary depth. Subsequently, they…

English-medium universities often accept scores from various English language proficiency (ELP) tests as evidence of ELP from non-English background students. This practice raises the question of how these tests compare in terms of their ability to predict academic achievement. This longitudinal study addresses this question by examining the…

Although the IELTS speaking test assesses English verbal-communication competence accurately and reliably, its traditional, retroactive scoring framework stops short of providing detailed diagnostic information about individual test-takers' specific domains of proficiency or deficiency. This study employed a cognitive diagnostic assessment (CDA)…

The current study explored and compared the employment of interactive and interactional metadiscourse markers (MDMs) by the International English Language Testing System (IELTS) speaking test takers at beginner, intermediate, and advanced levels. To conduct this discourse analysis research, a mixed-methods approach with concurrent transformative…

Despite extensive research on assessing collocational knowledge, valid measures of academic collocations remain elusive. With the present study, we employ an argument-based approach to validate two Academic Collocation Tests (ACTs) that assess the ability to recognize and produce academic collocations (i.e., two-word units such as "key…

The present study explored the effects of interactionist Dynamic Assessment (DA) and age on the writing accuracy of IELTS candidates. This research investigated the existence of an interactional effect between the age of learners and the type of treatment they received. First, 140 IELTS candidates were split into two age groups, adult and young.…

Many English-medium universities employ a compensatory model to establish cutscores on English language proficiency tests for student admissions. In this model, students can have different scores on different sections of the test provided their overall score meets the admission cutscore. This practice raises questions regarding potential variation…

Literacy is complex and impacts safety in nursing. When using language, nurses are constantly switching between medical language proficiency, academic language proficiency, and social language proficiency. The purpose of this mixed-methods study was to trial an English language exam specific to the nursing profession -- the Canadian English…

This evaluation report examines extensive reading (ER) speed and words read by students at a Japanese university using a digital ER platform called Xreading and compares them to standardized test reading performance using the International English Language Testing System (IELTS). The study focuses on first- and second-year students who…
