Professor Glenn Fulcher's research has influenced language testing and assessment in two ways: in proposing a new understanding of data-driven speaking test design, and in drawing attention to the core identity of language testers. The former has had a powerful impact on practical speaking testing and assessment. The latter has asked a very…

Cognitive diagnostic models (CDMs) have received much interest within the field of language testing over the last decade due to their great potential to provide diagnostic feedback to all stakeholders and ultimately improve language teaching and learning. A large number of studies have demonstrated the application of CDMs on advanced large-scale…

This report describes the development of efficient second language (L2) writing assessment tasks designed specifically for low-proficiency learners of English to be included in the "TOEFL® Essentials"™ test. Based on the can-do descriptors of the Common European Framework of Reference for Languages for the A1 through B1 levels of…

Nonverbal and other visual cues are well established as a critical component of human communication. Under most circumstances, visual information is available to aid in the comprehension and interpretation of spoken language. Citing these facts, many L2 assessment researchers have studied video-mediated listening tests through score comparisons…

This study examined whether reporting subscores for groups of items within a test section assessing a second-language modality (specifically reading or listening comprehension) added value from a measurement perspective to the information already provided by the section scores. We analyzed the responses of 116,489 test takers to reading and…

Despite calls for engaging assessments targeting young language learners (YLLs) between 8 and 13 years old, what makes assessment tasks engaging and how such task characteristics affect measurement quality have not been well studied empirically. Furthermore, there has been a dearth of validity research about technology-enhanced speaking tests for…

In the last 15 years or so, language testing practitioners have increasingly favored assessing vocabulary in context. The discrete-point vocabulary measure used in the old version of the Test of English as a Foreign Language (TOEFL) has long been criticized for encouraging test candidates to memorize wordlists out of context although test items…

The present study investigated the factor structure of a field trial sample of the Test of English as a Foreign Language™ Internet-based test (TOEFL® iBT). An item-level confirmatory factor analysis (CFA) was conducted for a polychoric correlation matrix of items on a test form completed by 2,720 participants in the 2003-2004 TOEFL iBT Field…

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…

The current study, carried out jointly by Test Development and Statistical Analysis staff at Educational Testing Service investigated the feasibility of the Automated Item Selection (AIS) procedure for the Test of English as a Foreign Language (TOEFL). Item-response theory (IRT)-based statistical specifications were developed. Two TOEFL test forms…

Several exploratory analyses of the fifths data generated by Test of English as a Foreign Language (TOEFL) item analyses were developed in order to evaluate the effects of options on the discriminability of difficult items and to identify difficult items with low, unreliable biserials that had been rejected by test developers, but for which…

This paper reports the results of generalizability theory (G) analyses done for new writing and speaking tasks for the Test of English as a Foreign Language (TOEFL). For writing, a special focus was placed on evaluating the impact on the reliability of the number of raters (or ratings) per essay (one or two) and the number of tasks (one, two, or…

A study examined the relationship of native language and level of English proficiency to the structure of the Test of English as a Foreign Language (TOEFL). Using all of the information provided by various responses to the test's items (the four alternatives, omitted, and not reached), the items' interrelations were analyzed by three-way…

One of the item types in the Listening Comprehension section of the Test of English as a Foreign Language (TOEFL) test is the dialogue. Because the dialogue item pool needs to have an appropriate balance of items at a range of difficulty levels, test developers have examined items at various difficulty levels in an attempt to identify their…

The Test of English as a Foreign Language (TOEFL) program is exploring a change in Section 3 of the TOEFL test that would replace the vocabulary subpart with additional reading comprehension questions. This study investigated the proposed revision in terms of the length and timing that would be necessary to address concerns of test speededness of…
