The goal of this paper is to find better ways to estimate the internal consistency reliability of scores on tests with a specific type of design that are often encountered in practice: tests with constructed-response items clustered into sections that are not parallel or tau-equivalent, and one of the sections has only one item. To estimate the…

The TOEFL Junior® tests are designed to evaluate young language students' English reading, listening, speaking, and writing skills in an English-medium secondary instructional context. This paper articulates a validity argument constructed to support the use and interpretation of the TOEFL Junior test scores for the purpose of placement, progress…

Cross-validation is a common statistical procedure applied to problems that are otherwise computationally intractable. It is often employed to assess the effectiveness of prediction procedures. In this report, cross-validation is discussed in terms of "U"-statistics. This approach permits consideration of the statistical properties of…

This paper presents a multidimensional model of variation in writing quality, register, and genre in student essays, trained and tested via confirmatory factor analysis of 1.37 million essay submissions to ETS' digital writing service, Criterion®. The model was also validated with several other corpora, which indicated that it provides a…

At a time when institutions of higher education are exploring alternatives to traditional admissions testing, institutions are also seeking to better support students and prepare them for academic success. Under such an engaged model, one may seek to measure not just the accumulated knowledge and skills that students would bring to a new academic…

This report provides a brief overview of how the "TOEIC"® program has adopted an argument-based approach to validity in order to support the use of the TOEIC tests. This approach emphasizes the need to explicitly state claims about the measurement quality and intended use of a test and to support those claims with evidence. This report…

Educational Testing Service (ETS), working with 21 U.S. law schools, evaluated the predictive validity of the GRE® General Test using a sample of 1,587 current and graduated law students. Results indicated that the GRE is a strong, generalizably valid predictor of first-year law school grades and that it provides useful information even when…

Forced-choice (FC) measures are becoming increasingly common in the assessment of personality for high-stakes testing purposes in both educational and organizational settings. Despite this, there has been relatively little research into the reliability of scores obtained from these measures, particularly when administered as a computerized…

In response to the calls for making key stakeholders' perspectives relevant in the test validation process, the study discussed in this report sought test-taker feedback as part of collecting validity evidence and supporting the ongoing field testing efforts of the new "TOEFL ITP"® Speaking section. Specifically, I aimed to investigate…

With advances in technology, researchers and test developers are developing new item types to measure complex skills like problem solving and critical thinking. Analyzing such items is often challenging because of their complicated response patterns, and thus it is important to develop psychometric methods for practitioners and researchers to…

Researchers, theorists, and practitioners have expressed a renewed interest in the longitudinal dynamics of personality characteristics in adulthood, including organic life span trajectories and their amenability to volitional change. However, this research has apparently not yet expanded to include the Dark Triad (psychopathy, narcissism,…

The "TOEFL Junior"® Standard test is a tool for measuring the English language skills of students ages 11+ who learn English as an additional language. It is a paper-based multiple-choice test and measures proficiency in three sections: listening, form and meaning, and reading. To date, empirical evidence provides some support for the…

Fifty years after the first international large-scale assessment (ILSA), participation in these studies continues to grow, with more than 50% of the world's countries participating. Concomitant with growth in ILSAs is an expansion in the diversity of participant countries with respect to languages, cultures, and educational perspectives and goals.…

In this report we provide preliminary evidence on the measurement characteristics for a new type of teaching performance assessment designed to be combined with complementary assessments of teacher content knowledge. The resulting test, which we refer to as the Foundational Assessment of Competencies for Teaching (FACT), is designed for use as…

The redesigned "TOEIC Bridge"® tests were designed to evaluate test takers' English listening, reading, speaking, and writing skills in the context of everyday adult life. In this paper, we summarize the initial validity argument that supports the use of test scores for the purpose of selection, placement, and evaluation of a test…
