Diagnostic classification models (DCMs) have recently become very popular both for research purposes and for real testing endeavors for student assessment. A plethora of DCM models give researchers and practitioners a wide range of options for student diagnosis and classification. One intriguing option that some DCM models offer is the possibility…

Unidimensionality is an important assumption of measurement but it is violated very often. Most of the time, tests are deliberately constructed to be multidimensional to cover all aspects of the intended construct. In such situations, the application of unidimensional item response theory (IRT) models is not justifieddue to poor model fit and…

Language learners are underserved if there are unlearned meanings of a word that they think they have already learned. For example, "circle" as a noun is well known, whereas its use as a verb is not. For artificial-intelligence-based support systems for learning vocabulary, assessing each learner's knowledge of such atypical but common…

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…

High stakes testing, such as IELTS, is designed to select individuals for decision-making purposes (Fulcher, 2013b). Hence, there is a slow-growing stream of research investigating the subskills of IELTS listening and, in feedback terms, its effects on individuals and educational programs. Here, cognitive diagnostic assessment (CDA) performs it…

Modern vocabulary size tests are generally based on the notion that the more frequent a word is in a language, the more likely a learner will know that word. However, this assumption has been seldom questioned in the literature concerning vocabulary size tests. Using the Vocabulary of American-English Size Test (VAST) based on the Corpus of…

This article aims to give a comprehensive guide to planning and designing vocabulary tests which include Identifying the skills to be covered by the test; outlining the course content covered; preparing a table of specifications that shows the skill, content topics and number of questions allocated to each; and preparing the test instructions. The…

This dissertation explored whether unnecessary linguistic complexity (LC) in mathematics and biology assessment items changes the direction and significance of differential item functioning (DIF) between subgroups emergent bilinguals (EBs) and English proficient students (EPs). Due to inconsistencies in measuring LC in items, Study One adapted a…

This reflection paper disseminates the design and implementation of an English placement test for first semester students from different majors. This design was carried out within the framework of a research project in a Colombian public university. The article has a twofold purpose: to scrutinize the stages leading to a test, and to highlight the…

Reverse engineering (RE) can play an important role in the re-designing tests in L2 English. It can also enrich the aim of teaching the same as raising children through academic achievement. In addition, it can play a key role in helping students understand how much their test is valid by using Standard reverse engineering (SRE). This paper is a…

Task difficulty is a critical issue affecting test developers. Controlling or balancing the item difficulty of an assessment improves its validity and discrimination. Test developers construct tests from the cognitive perspective, by making the test constructing process more scientific and efficient; thus, the scores obtained more precisely…

ELTeach is an online professional development program developed by Educational Testing Service (ETS) in collaboration with National Geographic Learning. The ELTeach program consists of two courses: English-for-Teaching and Professional Knowledge for English Language Teaching (ELT). Each course includes a coordinated assessment leading to a score…

Assessment is central in education and the teaching-learning process. This study attempts to explore the perspectives and views about quality assessment among teachers of English as a Foreign Language (EFL), and to find ways of promoting quality assessment. Quantitative methodology was used to collect data. To answer the study questions, a…

This review of research on assessment of second-language listening abilities looks at some testing issues and challenges (assessing higher-level skills, confounding of skills, assessing listening in oral interaction, authenticity), discusses assessment methods and techniques (test administration, item formats), and considers potential applications…
