This controlled experimental study investigated the interaction of variables associated with rating the pronunciation component of high-stakes English-language-speaking tests such as IELTS and TOEFL iBT. One hundred experienced raters who were all either familiar or unfamiliar with Brazilian-accented English or Papua New Guinean Tok Pisin-accented…

The aim of this study was to develop, for the benefit of both test takers and test score users, enhanced "TOEFL ITP"® test score reports that go beyond the simple numerical scores that are currently reported. To do so, we applied traditional scale anchoring (proficiency scaling) to item difficulty data in order to develop performance…

Stakeholders of language tests are often interested in subscores. However, reporting a subscore is not always justified; a subscore should provide reliable and distinct information to be worth reporting. When a subscore is used for decisions across multiple levels (e.g., individual test takers and schools), it needs to be justified for its…

Over the past 45 years, the construct of syntactic sophistication has been assessed in L2 writing using what Bulté and Housen (2012) refer to as absolute complexity (Lu, 2011; Ortega, 2003; Wolfe-Quintero, Inagaki, & Kim, 1998). However, it has been argued that making inferences about learners based on absolute complexity indices (e.g., mean…

This paper examines the uptake of Rasch measurement in language testing through a consideration of research published in language testing research journals in the period 1984 to 2009. Following the publication of the first papers on this topic, exploring the potential of the simple Rasch model for the analysis of dichotomous language test data, a…

Explored the relative contributions to Test of English as a Foreign Language (TOEFL) score dependability of various numbers of persons, items, subtests, languages, and their various interactions. Sampled 15,000 test takers, 1000 each from 15 different language backgrounds. (Author/VWL)

A multitask speaking measure consisting of both integrated and independent tasks is expected to be an important component of a new version of the TOEFL test. This study considered two critical issues concerning score dependability of the new speaking measure: How much would the score dependability be impacted by (1) combining scores on different…

This study applied generalizability theory to investigate the contributions of persons, items, sections, and language backgrounds to the score dependability of the Test of English for International Communication (TOEIC). I replicated and extended Brown's (1999) study of the Test of English as a Foreign Language (TOEFL), using data from two…

This study is part of a larger one examining the comparability of the First Certificate in English and the Test of English as a Foreign Language. The general assumption of unidimensionality and goodness-of-fit were tested. Findings raise questions about the consequences of rejecting or retaining misfitting items. (60 references) (LB)

The assumption called PIRC (proportional item response curve) was tested in which PIRC was used to predict item scores of selected examinees on selected items. Findings show approximate accuracies of prediction for PIRC, the three-parameter logist model, and a modified Rasch model. (12 references) (Author/LB)

The present study focuses on the task characteristics of reading passages and key sentences in a test of second language reading. Using a new methodological approach to describe variation in test task characteristics and explore how differences in these characteristics might relate to examinee performance, it posed the two following research…
