We investigate two research questions using a recent statewide transition from paper to computer-based testing: first, the extent to which test mode effects found in prior studies can be eliminated; and second, the degree to which online and paper assessments offer different information about underlying student ability. We first find very small…

Recent research has demonstrated an intersectional approach to the study of differential item functioning (DIF). This approach expands DIF to account for the interactions between what have traditionally been treated as separate grouping variables. In this paper, we compare traditional and intersectional DIF analyses using data from a state testing…

Providing appropriate test accommodations to most English language learners (ELLs) is important to facilitate meaningful inferences about learning. This study compared teacher large-scale test accommodation recommendations to those from a literature- and practitioner-grounded accommodation selection taxonomy. The taxonomy links student-specific…

Construct-irrelevant cognitive complexity of some items in the statewide grade-level assessments may impose performance barriers for students with disabilities who are ineligible for alternate assessments based on alternate achievement standards. This has spurred research into whether items can be modified to reduce complexity without affecting…

The Standards for Educational and Psychological Testing indicate that multiple sources of validity evidence should be used to support the interpretation of test scores. In the past decade, examinee response processes, as a source of validity evidence, have received increased attention. However, there have been relatively few methodological studies…

Item response theory (IRT) methods are generally used to create score scales for large-scale tests. Research has shown that IRT scales are stable across groups and over time. Most studies have focused on items that are dichotomously scored. Now Rasch and other IRT models are used to create scales for tests that include polytomously scored items.…

Two models are presented in this article for estimating the proportion of students who would pass all of three or more content area tests given that none have actually been tested in more than two of the content areas. The first model allows one to estimate the proportion of students who would pass all of three or more content area tests from the…

Eighth grade teachers in three local school districts helped customize two standardized norm-referenced tests for ninth graders to investigate effects of deleting some items and adding locally constructed items. Results indicate that percentile ranks for the customized tests could be very different from those for the complete test. (SLD)

A general approach to the identification of individuals mismeasured by a standardized psychological test is reviewed. The method, originated by M. V. Levine and F. Drasgow (1988), has the advantage of statistical optimality. Use of optimal methods requires a psychometric model for normal responding and one for aberrant responding. (SLD)

Current coaching practices used in training test wiseness for analogy items on standardized test batteries were investigated in a 3-group design involving about 100 undergraduates in each condition. The largest improvement came in items in the middle range of difficulty, but overall effects of coaching were important. (SLD)

Methods for detecting copying of multiple-choice test responses are reviewed and compared with respect to their effectiveness and the practicality of their application for groups of varying sizes. Reasons why effective detection methods are seldom applied in standardized and classroom testing are discussed. (SLD)

The adequacy of linking statewide standardized test results to the National Assessment of Educational Progress by using equipercentile equating procedures was investigated using statewide mathematics data from four states. Results suggest that the linkings are not sufficiently trustworthy to make comparisons based on the tails of the distribution.…

The effects of using item response theory (IRT) ability estimates based on customized tests formed by selecting areas from a nationally standardized achievement test were examined. For some populations, in some conditions, IRT ability estimates can be equivalent to scores based on full-length tests. (SLD)

Federal law requires that individuals with handicapping conditions be administered assessments in ways that accommodate their disabilities without penalizing them. Validation studies are needed to evaluate the meaning of scores resulting from nonstandard test administrations. The limited number of these studies to date is reviewed. (SLD)

The validity of several criticisms of objective tests is addressed, and the viability of some alternatives to objective testing is discussed. Evidence against multiple-choice tests is not as strong as has been claimed. Authentic assessments may not always be better, and research about new forms of assessment is necessary. (SLD)
