Compares the effects of specific and general abilities on the reading and mathematics achievement of students from three ethnic groups. Results suggest that specific abilities are important for understanding student achievements, and that the same abilities are important for all ethnic groups. (Author/MKA)

Extended the use of a beta prior in trait estimation to the maximum expected a posteriori (MAP) method of Bayesian estimation. This new method, essentially unbiased MAP, was compared with MAP, essentially unbiased expected a posteriori, weighted likelihood, and maximum-likelihood estimation methods. The new method significantly reduced bias in…

The major youth psychotherapy meta-analyses have relied on published studies, which may have led to biased effect size estimates. To examine this possibility, the authors compared 121 dissertations with 134 published studies and found the following: (a) few differences on individual methodological variables, but, overall, stronger methodology in…

The efficiency of a new strategy to identify back random responding (BRR) on the Personality Assessment Inventory (L. C. Morey, 1991) was studied using random manipulations of item responses from community (904 adult nonpatients) and clinical (1,079 adult patients) respondents. The strategy involved a comparison of short-form and full-instrument T…

Score equity assessment (SEA) is introduced, and placed within a fair assessment context that includes differential prediction or fair selection and differential item functioning. The notion of subpopulation invariance of linking functions is central to the assessment of score equity, just as it has been for differential item functioning and…

Longer pieces are published in this "Further Comment" section, in full or in part, at the Editors' discretion. Authors of the articles under discussion are invited to respond. In this section, the…

This paper focused on the assessment of phonological skills amongst children with developmental dyslexia. Findings from assessments of English and Hungarian monolingual children with and without literacy deficits and bilingual Filipino children with and without literacy deficits in English indicated that performance on phonological-based tasks…

The purpose of this article is to present a working definition of the term "culture," as well as to describe and demonstrate a comprehensive framework for evaluating hypotheses about cultural bias in educational testing. The framework is demonstrated using 5th-grade reading and language arts data from the Terra Nova test (CTB/McGraw-Hill, 1999).…

Test bias research with Native American participants is uncommon, although individual tests of intelligence are often used with Native American students to determine eligibility for special education services. Only two studies with minimally adequate sample sizes have addressed the structural validity of major tests of intelligence in Native…

The study evaluated the comparability of two versions of a certification test: a paper-and-pencil test (PPT) and computer-based test (CBT). An effect size measure known as Cohen's d and differential item functioning (DIF) analyses were used as measures of comparability at the test and item levels, respectively. Results indicated that the effect…

In this article, the author presents the story of Hope--an education student who, despite many successes, was consistently unable to pass the reading portion of a screening test (Praxis I) that is a prerequisite to student teaching in her home state of Georgia. Hope's only trouble was the fact that she was a slow reader due to attention deficit…

Research has established that a variety of factors predict educators' perceptions of students' performance; however, no studies have looked at the impact of educators' political views. The present experiment investigated the effect of educators' political biases on their grading of student essays. Participants included 122 volunteers who were…

There has been considerable research regarding the extent to which psychometric sound assessments sometimes yield individual score estimates that are inconsistent with the response patterns of the individual. It has been suggested that individual response patterns may differ from expectations for a number of reasons, including subject motivation,…

Sometimes assessments that work in theory fall apart in reality. This article discusses the unique learning-measurement system in Nebraska. Instead of relying on statewide standardized tests to comply with the accountability requirements of the federal No Child Left Behind Act--as is the case in the other 49 states--districts in Nebraska use their…

Estimating the validity of a test is only one concern for the human resources professional developing a personnel selection battery. An equally important concern is whether the test will result in adverse impact against a member of a protected class. It would be useful if the probability of adverse impact could be estimated prior to spending time…
