Lexical diversity (LD) is an important indicator of second language lexical development. Much research has investigated LD indices, with a focus on learners of English. However, further research is needed in languages that are typologically distinct from English, such as Korean. In this study, we evaluated the reliability and validity of LD…

Chulalongkorn University Language Institute (CULI) test was developed as a local standardised test of English for professional and international communication. To ensure that the CULI test fulfils its intended purposes, this study employed Kane's argument-based validation and Rasch measurement approaches to construct the validity argument for 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…

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…

The TOEFL Junior® tests are designed to evaluate young language students' English reading, listening, speaking, and writing skills in an English-medium secondary instructional context. This paper articulates a validity argument constructed to support the use and interpretation of the TOEFL Junior test scores for the purpose of placement, progress…

Among the variety of selected response formats used in L2 reading assessment, multiple-choice (MC) is the most commonly adopted, primarily due to its efficiency and objectiveness. Given the impact of assessment results on teaching and learning, it is necessary to investigate the degree to which the MC format reliably measures learners' L2 reading…

In this Brief Report, we describe an evaluation of and revisions to a rubric adapted from the Jacobs et al.'s (1981) ESL COMPOSITION PROFILE, with four rubric categories and 20-point rating scales, in the context of an intensive English program writing placement test. Analysis of 4 years of rating data (2016-2021, including 434 essays) using…

Foreign language placement testing, an important component in university foreign language programs, has received considerable, but not copious, attention over the years in second language (L2) testing research (Norris, 2004), and it has been mostly concentrated on L2 English. In contrast to validation research on L2 English placement testing, the…

The current study explores the impact of varying multiple-choice question preview and presentation formats in a test of second language listening proficiency targeting different levels of text comprehension. In a between-participant design, participants completed a 30-item test of listening comprehension featuring implicit and explicit information…

The extensive use of automated speech scoring in large-scale speaking assessment can be revolutionary not only to test design and rating, but also to the learning and instruction of speaking based on how students and teachers perceive and react to this technology. However, its washback remained underexplored. This mixed-method study aimed to…

Background: Vocabulary knowledge (VK) and morphological awareness (MA) are crucial linguistic variables for reading comprehension. However, the extent to which MA subskills are intertwined with different facets of VK in their contributions to reading comprehensions, and how MA influences the reading abilities of English as a foreign language (EFL)…

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…

While many studies have addressed the benefits of technology-assisted L2 writing, limited research has delved into how generative artificial intelligence (GAI) supports students in completing their writing tasks in Mandarin Chinese. In this study, 26 university-level Mandarin Chinese foreign language students completed two writing tasks on two…

This study introduces the first Arabic Vocabulary Levels Test (Arabic-VLT), created for foreign learners of Arabic. We present compelling evidence to substantiate its validity and reliability. The Arabic-VLT was developed according to five levels, beginning with the most frequently used words (Level 1) to the least frequently used ones (Level 5),…

Extensive oral tasks or monologues of different types (e.g., presentations, storytelling) are often used as second language acquisition tasks in the fields of language learning and language testing. Pre-task planning time is a common provision to test-takers who may use different strategies to prepare their response. High-stakes tests, such as the…
