Research into self-regulating capacity in vocabulary learning is recognized as a significant topic within the second language domain. The self-regulating capacity in vocabulary learning scale (SRCvoc; Tseng et al. 2006) is arguably the most widely used tool for assessing this construct. The common factor model, which is applied through…

C-Test is a gap-filling test designed to measure first and second language proficiency. Over the past four decades, researchers have shown the fit of C-Test data to parametric item response theory (IRT) models, but no study so far has shown the fit of C-Tests to nonparametric IRT models. The purpose of this study is to contribute to the ongoing…

Recently, psychometricians and researchers have voiced their concern over the exploration of language test items in light of Messick's validation framework. Validity has been central to test development and use; however, it has not received due attention in language tests having grave consequences for test takers. The present study sought to…

Various stakeholders, such as policymakers and educators, require diagnostic feedback and actionable test results. One particular context in which fine-grained test results are of utmost importance is English language proficiency (ELP) assessments as they are used for critical decisions for students. Diagnostic classification models (DCMs) afford…

In the US K-12 public school settings, each state's annual English language proficiency (ELP) assessment, as part of an educational accountability system, has tremendous impact on English learner (EL) students' academic paths and success. It is thus critical to establish a robust validation framework and empirical evidence to ensure that states'…

The practice of second language (L2) speech perception has traditionally relied on equal-interval perceptual scales and novice listeners' (NLs) impressionistic judgments of constructs such as accentedness and comprehensibility (Munro & Derwing, 2011). However, issues have surfaced with respect to how well NLs can use these scales, whether they…

Recently a novel instrument -- the Core Academic Language Instrument (CALS-I) -- aimed at testing a constellation of school-relevant English language skills was developed and validated for use in the United States (Uccelli, Barr, Dobbs, Galloway, Meneses and Sánchez, 2015. Core Academic Language Skills: An expanded operational construct and a…

Background and Context: Despite the increasing implementation of coding in early curricula, there are few valid and reliable assessments of coding abilities for young children. This impedes studying learning outcomes and the development and evaluation of curricula. Objective: Developing and validating a new instrument for assessing young…

Technology-enhanced items (TEIs) are innovative, computer-delivered test items that allow test takers to better interact with the test environment compared to traditional multiple-choice items (MCIs). The interactive nature of TEIs offer improved construct coverage compared with MCIs but little research exists regarding students' performance on…

Purpose: The current study applies an innovative approach to the assessment of second language listening comprehension skills. This is an important focus in need of innovation because scores generated through language assessment tasks should reflect variation in the target skill and the literature broadly suggests that conventional methods of…

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…
