The rise in the affordability of quality video production equipment has resulted in increased interest in video-mediated tests of foreign language listening comprehension. Although research on such tests has continued fairly steadily since the early 1980s, studies have relied on analyses of raw scores, despite the growing prevalence of item…

Testlets are subsets of test items that are based on the same stimulus and are administered together. Tests that contain testlets are in widespread use in language testing, but they also share a fundamental problem: Items within a testlet are locally dependent with possibly adverse consequences for test score interpretation and use. Building on…

In this study, differential item functioning (DIF) trends were examined for English language learners (ELLs) versus non-ELL students in third and tenth grades on a large-scale reading assessment. To facilitate the analyses, a meta-analytic DIF technique was employed. The results revealed that items requiring knowledge of words and phrases in…

This study examined the relative effectiveness of the multidimensional bi-factor model and multidimensional testlet response theory (TRT) model in accommodating local dependence in testlet-based reading assessment with both dichotomously and polytomously scored items. The data used were 14,089 test-takers' item-level responses to the…

The research described in this article investigates test takers' cognitive processing while completing onscreen IELTS (International English Language Testing System) reading test items. The research aims, among other things, to contribute to our ability to evaluate the cognitive validity of reading test items (Glaser, 1991; Field, in press).…

This study examined the influence of prompt characteristics on the averages of all scores given to test taker responses on the TOEFL iBT[TM] integrated Read-Listen-Write (RLW) writing tasks for multiple administrations from 2005 to 2009. In the context of TOEFL iBT RLW tasks, the prompt consists of a reading passage and a lecture. To understand…

This study examines the development and evaluation of a bilingual Vocabulary Size Test (VST, Nation, 2006). A bilingual (English-Russian) test was developed and administered to 121 intermediate proficiency EFL learners (native speakers of Russian), alongside the original monolingual (English-only) version of the test. A comparison of the bilingual…

The important yet under-researched role of item writers in the selection and adaptation of texts for high-stakes reading tests is investigated through a case study involving a group of trained item writers working on the International English Language Testing System (IELTS). In the first phase of the study, participants were invited to reflect in…

This paper reports on an investigation of the potential for a shared-L1 advantage on an academic English listening test featuring speakers with L2 accents. Two hundred and twelve second-language listeners (including 70 Mandarin Chinese L1 listeners and 60 Japanese L1 listeners) completed three versions of the University Test of English as a Second…

This study tracked gender differential item functioning (DIF) on the English subtest of the Korean College Scholastic Aptitude Test (KCSAT) over a nine-year period across three data points, using both the Mantel-Haenszel (MH) and item response theory likelihood ratio (IRT-LR) procedures. Further, the study identified two factors (i.e. reading…

The Assessment of Language Competence (ALC) certificates is an annual, international testing program developed by the Australian Council for Educational Research to test the listening and reading comprehension skills of lower to middle year levels of secondary school. The tests are developed for three levels in French, German, Italian and…

Title III of Public Law 107-110 (No Child Left Behind; NCLB) provided for creation of assessments of English language learners (ELLs) and established, through the Enhanced Assessment Grant program, a platform from which four consortia of states developed ELL tests aligned to rigorous statewide content standards. Those four tests (ACCESS for ELLs,…

The purpose of this study was to explore whether the results of Tree Based Regression (TBR) analyses, informed by a validated cognitive model, would enhance the interpretation of item difficulties in terms of the cognitive processes involved in answering the reading items included in two forms of the Michigan English Language Assessment Battery…

Advances in natural language processing (NLP) and automatic speech recognition and processing technologies offer new opportunities for language testing. Despite their potential uses on a range of language test item types, relatively little work has been done in this area, and it is therefore not well understood by test developers, researchers or…

Noting the widespread use of multiple-choice items in tests in English language education in Thailand, this study compared their effect against that of constructed-response items. One hundred and fifty-two university undergraduates took a test of English structure first in constructed-response format, and later in three, stem-equivalent…
