This study examines potential assessment bias based on students' primary language status in PISA 2018. Specifically, multilingual (MLs) and nonmultilingual (non-MLs) students in the United States are compared with regard to their response time as well as scored responses across three cognitive domains (reading, mathematics, and science).…

In an article published in "Educational Measurement: Issues and Practice," Gaertner and McClarty (2015) discuss a college readiness index based, in part, on nonacademic or noncognitive factors measured in middle school. Such an index is laudable as it incorporates important constructs beyond academic achievement measures that may be…

The educational literature, the popular press, and educated laypeople have all echoed a conclusion from the book "Academically Adrift" by Richard Arum and Josipa Roksa (which has now become received wisdom), namely, that 45% of college students showed no significant gains in critical thinking skills. Similar results were reported by…

An effect size of about 0.70 (or 0.40-0.70) is often claimed for the efficacy of formative assessment, but is not supported by the existing research base. More than 300 studies that appeared to address the efficacy of formative assessment in grades K-12 were reviewed. Many of the studies had severely flawed research designs yielding…

There is significant potential for error in long production processes that consist of sequential stages, each of which is heavily dependent on the previous stage, such as the SER (Scoring, Equating, and Reporting) process. Quality control procedures are required in order to monitor this process and to reduce the number of mistakes to a minimum. In…

The historic origins of measurement are traced, and the basic requirements for fundamental measurement are outlined. Studying the history of social science measurement shows specific pitfalls the researcher must avoid. Applications of item response theory to social science measurement are discussed. (SLD)

Some of the challenges that test publishers face in constructing educational assessments that meet high technical quality as prescribed in the "Standards for Educational and Psychological Testing" (AERA, APA, NCME, 1999) are examined. Federal educational initiatives are used to illustrate demands on technical quality that challenge the efforts of…

This article examines how psychometric models based on certain assumptions have come to be used counterproductively by many practitioners in ways that limit the kinds of conclusions that can be made. The general problem of the context's influence on performance is discussed, and some implications are drawn. (SLD)

Researchers in the field of educational measurement need to monitor their own actions to keep their achievements in perspective. Some possible symptoms of obsession with their own significance are explored. Pride, destructive criticism, and misusing others to advance oneself are flaws researchers should strive to eradicate. (SLD)

Practices identified by experts as critical variables in eliciting writing samples were checked against 12 randomly selected studies using holistic ratings to derive descriptions of inferential statistical results for described samples. The studies often lacked precise information about these variables, limiting understanding of writing evaluation…

In 1987, a survey report by J. Cannell was published criticizing state reports based on national standardized testing of elementary school students that indicated that all 50 states were above the national average. This phenomenon--known as the "Lake Wobegon Effect"--is analyzed. Technical problems with the study are considered. (TJH)
