The emergence of digital-first assessments is prompting reconsideration of, and innovation in, aspects of psychometrics, test validation, and test use. Using the Duolingo English Test (DET) as an example, this three-paper series seeks to address issues concerning the estimation of classification consistency and the reporting of results for such…

Developing a diagnostic tool within the diagnostic measurement framework is the optimal approach to obtain multidimensional and classification-based feedback on examinees. However, end users may seek to obtain diagnostic feedback from existing item responses to assessments that have been designed under either the classical test theory or item…

This paper presents an approach to standard setting that combines the prototype group method (PGM; Eckes, 2012) with a receiver operating characteristic (ROC) analysis. The combined PGM-ROC approach is applied to setting cut scores on a placement test of English as a foreign language (EFL). To implement the PGM, experts first named learners whom…

Despite all the progress that has been made in research on language learning strategies since the publication of Rubin's (1975) seminal paper on good language learners, there are areas that have been neglected by strategy experts. Perhaps the most blatant manifestation of this neglect is the paucity of research into grammar learning strategies…

This article compares second language test-takers' performance on an academic listening test in an audio-only mode versus an audio-video mode. A new method of classifying video-based visuals was developed and piloted, which used L2 expert opinions to place the video on a continuum from being content-deficient (not helpful for answering…

The purpose of this study was to enhance the meaning of the scores of an English-language test by developing performance levels and descriptors for reporting overall test performance. The levels and descriptors were intended to accompany the total scale scores of TOEFL Junior® Standard, an international test of English as a second/foreign…

Diagnostic classification models (aka cognitive or skills diagnosis models) have shown great promise for evaluating mastery on a multidimensional profile of skills as assessed through examinee responses, but continued development and application of these models has been hindered by a lack of readily available software. In this article we…

This study aims to examine the relationship between reading comprehension and lexical and grammatical knowledge among English as a foreign language students by using an Artificial Neural Network (ANN). There were 825 test takers administered both a second-language reading test and a set of psychometrically validated grammar and vocabulary tests.…

Review of 78 evaluations for 29 young children examined practices used in assessment of autism spectrum disorders in three settings: public schools, developmental disabilities eligibility determinations, and our hospital-based early childhood mental health program. While similar rates of classification of autism spectrum disorders were found…

The present study investigated the functioning of three psychometric models for cognitive diagnosis--the general diagnostic model, the fusion model, and latent class analysis--when applied to large-scale English as a second language listening and reading comprehension assessments. Data used in this study were scored item responses and incidence…

English language learners with disabilities (ELLWD) face many challenges in their academic career. Learning a new language and coping with their disabilities create obstacles in their academic progress. Variables relegating accessibility of assessments for students with disabilities and ELL students may seriously hinder the academic performance of…

Assessments in English that are constructed for native English speakers may not provide valid inferences about the achievement of English language learners (ELLs). The linguistic complexity of the test items that are not related to the content of the assessment may increase the measurement error, thus reducing the reliability of the assessment.…
