Random Equating (RE) and Heuristic Approach (HA) are two linking procedures that may be used to compare the scores of individuals in two tests that measure the same latent trait, in conditions where there are no common items or individuals. In this study, RE--that may only be used when the individuals taking the two tests come from the same…

Multidimensional forced-choice (MFC) items have been found to be useful to reduce response biases in personality assessments. However, conventional scoring methods for the MFC items result in ipsative data, hindering the wider applications of the MFC format. In the last decade, a number of item response theory (IRT) models have been developed,…

Examinees who take high-stakes assessments are usually given an opportunity to repeat the test if they are unsuccessful on their initial attempt. To prevent examinees from obtaining unfair score increases by memorizing the content of specific test items, testing agencies usually assign a different test form to repeat examinees. The use of multiple…

Large data sets from a state reading assessment for third and fifth graders were analyzed to examine differential item functioning (DIF), differential distractor functioning (DDF), and differential omission frequency (DOF) between students with particular categories of disabilities (speech/language impairments, learning disabilities, and emotional…

Percentile scores appear to be the easiest standardized test scores for parents to understand. Yet in this true-false test, Hills reveals commonly held misconceptions about percentile score reports. (LC)

Three computerized adaptive tests (CATs) in mathematics, reading, and writing were administered to 628 community college students to determine whether examinees of different ethnic, gender, ability, and age groups, and computer experience were differentially affected. Some differences exist; however, they do not preclude use of CATs. (SLD)

The relevance of state results on tests of the National Assessment of Educational Progress (NAEP) is illustrated with data from the "Digest of Education Statistics--1990" (U.S. Department of Education). Evidence indicates that the contributions of state differences such as economic or demographic differences to NAEP results cannot be…

The effects of test performance of differentially written multiple-choice tests and test takers' cognitive style were studied for 47 graduate students and 35 public school and college teachers. Adhering to test-writing item guidelines resulted in mean scores basically the same for two groups of differing cognitive style. (SLD)
