Jessica Wu is Research and Development Program Director at the Language Training and Testing Center (LTTC) in Taipei, Taiwan. Jessica has been deeply involved in the development and validation of the General English Proficiency Test (GEPT) in addition to a number of other foreign language testing programs. Her research focuses on speaking…

This mixed methods study compared IELTS examiners' scores when assessing spoken performances under live and two 'non-live' testing conditions using audio and video recordings. Six IELTS examiners assessed 36 test-takers' performances under the live, audio, and video rating conditions. Scores in the three rating modes were calibrated using the…

The COVID-19 pandemic led to rapid innovation among language assessment developers who had to adapt their testing processes to address various restrictions from governments and institutions. This overview introduces some of the challenges and opportunities test developers grappled with during this period as well as introduces the six commentaries…

Thinking skills play a critical role in determining language performance. Recent advancement in cognitive diagnostic modelling (CDM) provides a powerful tool for obtaining fine-grained information regarding these thinking skills during reading. Studies are scant, however, exploring the relations between thinking skills and language performance,…

In Dynamic Assessment (DA), the observation that individuals respond differently to support, or mediation, is important for diagnoses of development. The concept of learning potential refers to openness to mediation, i.e., the extent of change to performance when mediation is available, which may suggest learners will need less overall instruction…

Prompted by Taiwanese university students' increasing demand for English proficiency assessment, the absence of a test designed specifically for this demographic subgroup, and the lack of a localized and freely-accessible proficiency measure, this project set out to develop and validate a computerized adaptive English proficiency testing (E-CAT)…

This paper examined to what extent causal explanation speaking tasks (CESTs) are cognitively appropriate for assessing young language learners' (YLLs) L2 speaking. Ninety-six YLLs (48 from Grade 4 and 6 each) in China performed two CESTs in both L1 (Chinese) and L2 (English). They also completed receptive and productive L2 vocabulary size tests.…

The effects of question or task complexity on second language speaking have traditionally been investigated using complexity, accuracy, and fluency measures. Response processes in speaking tests, however, may manifest in other ways, such as through nonverbal behavior. Eye behavior, in the form of averted gaze or blinking frequency, has been found…

Recently, research in second language acquisition has seen an increased attention on low-educated low-literate (LESLLA) learners. However, few of the existing instruments to measure L2 proficiency have been validated for use with this population. In this paper, we examine how adult L2 learners with diverging educational backgrounds perform on and…

Young Indigenous students with a language background of emergent, unrecognised, and/or non-prestigious contact languages are commonly by-passed as English language learners (ELLs). Consequently, they are taught and assessed via undifferentiated mainstream pedagogy and testing, generally characterised by reported underachievement. Long-term social…

The Common European Framework of Reference for Languages Companion Volume (CEFR CV) emphasizes macro-functions of language (i.e., reception, production, interaction, and mediation). However, there seems to be little consensus on whether the macro-functions are commensurable with CEFR-based proficiency tests. This paper focuses on the Examination…

The TOEFL iBT test was introduced in 2005 to better reflect the language demands of real-life academic tasks than did previous versions of the test. The task-based design of the test was intended to support the interpretation of its scores as a trustworthy measure of international students' ability to use English in an academic environment. Until…

The present study examined the performance of the bi-factor multidimensional item response theory (MIRT) model and higher-order (HO) cognitive diagnostic models (CDM) in providing diagnostic information and general ability estimation simultaneously in a listening test. The data used were 1,611 examinees' item-level responses to an in-house EFL…

As the number of candidates who repeat English language proficiency tests more than once to meet a certain cutscore (e.g., for university admission) or to demonstrate progress (e.g., after instruction) continues to increase dramatically, there is a need for more research on the attributes and test performance of test repeaters. This article…

This article presents a critical review of the Texas English Language Proficiency Assessment System (TELPAS), a large scale standardized English language proficiency (ELP) assessment developed by the Texas Education Agency (TEA) and administered since 2004. TELPAS is used as an annual summative assessment for all English Learners (ELs) in grades…
