Although there is abundant evidence for the use of first-language (L1) knowledge by bilinguals when using a second language (L2), investigation into the impact of L1 knowledge in large-scale L2 language assessments and discussion of how such impact may be controlled has received little attention in the language assessment literature. This study…

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…

Originally designed to measure reading and passage comprehension in L1 readers, cloze tests continue to be used for L2 assessment purposes. However, there remain disputes about whether or not cloze items can measure beyond local comprehension information, as well as whether or not they are purely a test of reading alone, or if performance can be…

This study explored the interplay between content knowledge and reading ability in a large-scale multistage adaptive English for academic purposes (EAP) reading assessment at a range of ability levels across 1-12 graders. The datasets for this study were item-level responses to the reading tests of ACCESS for ELLs Online 2.0. A sample of 10,000…

Language proficiency testing serves an important function of classifying examinees into different categories of ability. However, misclassification is to some extent inevitable and may have important consequences for stakeholders. Recent research suggests that classification efficacy may be enhanced substantially using computerized adaptive…

Vocabulary's relationship to reading proficiency is frequently cited as a justification for the assessment of L2 written receptive vocabulary knowledge. However, to date, there has been relatively little research regarding which modalities of vocabulary knowledge have the strongest correlations to reading proficiency, and observed differences have…

Reading comprehension tests are often assumed to measure the same, or at least similar, constructs. Yet, reading is not a single but a multidimensional form of processing, which means that variations in terms of reading material and item design may emphasize one aspect of the construct at the cost of another. The educational systems in Denmark,…

This study investigates test-takers' processing while completing banked gap-fill tasks, designed to test reading proficiency, in order to test theoretically based expectations about the variation in cognitive processes of test-takers across levels of performance. Twenty-eight test-takers' eye traces on 24 banked gap-fill items (on six tasks) were…

The present study examines the relative importance of attributes within and across items by applying four cognitive diagnostic assessment models. The current study utilizes the function of the models that can indicate inter-attribute relationships that reflect the response behaviors of examinees to analyze scored test-taker responses to four forms…

Reading-to-write (RTW) tasks are becoming increasingly popular and have already been used in several high-stakes English proficiency exams, either replacing or complementing a prompt-based essay test. However, it is still not clear that what accounts for successful or unsuccessful performance on an integrated reading-writing task is owing to the…

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 testlet-based…

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…

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). The…

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…

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…
