Foreign language testing is a multi-dimensional phenomenon and obtaining objective and error-free scores on learners' language skills is often problematic. While assessing foreign language performance on high-stakes tests, using different testing approaches including Classical Test Theory (CTT), Generalizability Theory (GT) and/or Item Response…

In the process of measuring and assessing high-level cognitive skills, interference of rater errors in measurements brings about a constant concern and low objectivity. The main purpose of this study was to investigate the impact of rater training on rater errors in the process of assessing individual performance. The study was conducted with a…

Research on assessing English as a foreign language (EFL) development has been growing recently. However, empirical evidence from longitudinal analyses based on substantial samples is still needed. In such settings, tests for measuring language development must meet high standards of test quality such as validity, reliability, and objectivity, as…

The purpose of this study was to map the Chulalongkorn University Test of English Proficiency, or the CU-TEP, to the Common European Framework of Reference (CEFR) by employing a standard setting methodology. Thirteen experts judged 120 items of the CU-TEP using the Yes/No Angoff technique. The experts decided whether or not a borderline student at…

As a property of test scores, reliability/dependability constitutes an important psychometric consideration, and it underpins the validity of measurement results. A review of interpreter certification performance tests (ICPTs) reveals that (a) although reliability/dependability checking has been recognized as an important concern, its theoretical…

Considering scoring validity as encompassing both reliable rating scale use and valid descriptor interpretation, this study reports on the validation of a CEFR-based scale that was co-constructed and used by novice raters. The research questions this paper wishes to answer are (a) whether it is possible to construct a CEFR-based rating scale with…

Stewart questioned Beglar's use of Rasch analysis of the Vocabulary Size Test (VST) and advocated the use of 3-parameter logistic item response theory (3PLIRT) on the basis that it models a non-zero lower asymptote for items, often called a "guessing" parameter. In support of this theory, Stewart presented fit statistics derived from…

Language learners' productive role in teaching and learning processes has recently been the focus of attention. Therefore, this study aimed at investigating the effect of oral vs. written output-based instruction on English as a foreign language (EFL) learners' vocabulary learning with a focus on reflective vs. impulsive learning styles. To this…

An important gap in the field of second language vocabulary assessment concerns the lack of validated tests measuring aural vocabulary knowledge. The primary purpose of this study is to introduce and provide preliminary validity evidence for the Listening Vocabulary Levels Test (LVLT), which has been designed as a diagnostic tool to measure…

The Yes/No Angoff and Bookmark method for setting standards on educational assessment are currently two of the most popular standard-setting methods. However, there is no research into the comparability of these two methods in the context of language assessment. This study compared results from the Yes/No Angoff and Bookmark methods as applied to…

The study scrutinized the probable interaction between using cognitive test-taking strategies, reading proficiency, and reading comprehension test performance of Iranian postgraduate students, who studied English as a foreign language. The study also probed the extent to which the participants' test performance was related to the use of certain…
