In many countries, standardized math tests are important for achieving academic success. Here, we examine whether content of items, the story that explains a mathematical question, biases performance of low-SES students. In a large-scale cohort study of Trends in International Mathematics and Science Studies (TIMSS)--including data from 58…

I analyzed a corpus of the international English language testing system (IELTS) comprising 256 listening sections (1996-2021). The primary objective of the study was to gain insights into the assumptions made by test designers regarding the real-life contexts that test-takers will encounter. Overall, 15 superordinate topic areas and 300 subtopics…

Advancement of testing of mathematical problem-solving skills calls for open-ended, realistic tasks particularly susceptible to bias, compromising the score validity and fairness of tests. Informed by universal design principles, this study framed 360 prototype items developed for the "Problem-solving Measures Grades 6-8 Computer Adaptive…

Evidence of comparability is generally needed whenever there are variations in the conditions of an assessment administration, including variations introduced by the administration of an assessment on multiple digital devices (e.g., tablet, laptop, desktop). This article is meant to provide a comprehensive examination of issues relevant to the…

In recent years, large-scale international assessments have been increasingly used to evaluate and compare the quality of education across regions and countries. However, measurement variance between different versions of these assessments often posts threats to the validity of such cross-cultural comparisons. In this study, we investigated the…

In organizational and educational practices, sensitivity reviews are commonly advocated techniques for reducing test bias and enhancing fairness. In the present paper, results from two studies are reported which investigate how effective individuals are at detecting problematic test content and the influence such content has on important testing…

Kindergarten entry assessments (KEAs) have increasingly been incorporated into state education policies over the past 5 years, with much of this interest stemming from Race to the Top--Early Learning Challenge (RTT-ELC) awards, Enhanced Assessment Grants, and nationwide efforts to develop common K-12 state learning standards. Drawing on…

Equating test forms is an essential activity in standardized testing, with increased importance with the accountability systems in existence through the mandate of Adequate Yearly Progress. It is through equating that scores from different test forms become comparable, which allows for the tracking of changes in the performance of students from…

The linguistic demand of spoken instructions on individually administered norm-referenced psychological and educational tests is of concern when examining individuals who have varying levels of language processing ability or varying cultural backgrounds. The authors present a new method for analyzing the level of verbosity, complexity, and total…

Many of the instruments developed for research use by the chemistry education community are relatively new. Because psychometric evidence dictates the validity of interpretations made from test scores, gathering and reporting validity and reliability evidence is of utmost importance. Therefore, the purpose of this study was to investigate what…

In this article, the author describes his project to take every standardized exam English majors students take. During the summer and fall semesters of 2012, the author signed up for and took the GRE General Test, the Praxis Content Area Exam (English Language, Literature, and Composition: Content Knowledge), the Senior Major Field Tests in…

In the attempt to identify or prevent unfair tests, both quantitative analyses and logical evaluation are often used. For the most part, fairness evaluation is a pragmatic attempt at determining whether procedural or substantive due process has been accorded to either a group of test takers or an individual. In both the individual and comparative…

In this article, I specify a conceptual framework for test validity research on content assessments taken by English language learners (ELLs) in U.S. schools in grades K-12. This framework is modeled after one previously delineated by Willingham et al. (1988), which was developed to guide research on students with disabilities. In this framework…

This article reviews research on differential item functioning (DIF) in language testing conducted primarily between 1990 and 2005 with an eye toward providing methodological guidelines for developing, conducting, and disseminating research in this area. The article contains a synthesis of 27 studies with respect to five essential sets of…

Test-item writing efforts typically results in item pools with an undesirable correlational structure between the content attributes of the items and their statistical information. If such pools are used in computerized adaptive testing (CAT), the algorithm may be forced to select items with less than optimal information, that violate the content…
