Considerable research has examined the use of rapid guessing measures to identify disengaged item responses. However, little is known about students who rapidly guess over the course of several tests. In this study, we use achievement test data from six administrations over three years to investigate whether rapid guessing is a stable trait-like…

This chapter introduces theory that undergirds the role of testing adaptations in assessment, provides examples of item modifications and testing accommodations, reviews research relevant to each, and introduces a new paradigm that incorporates opportunity to learn (OTL), academic enablers, testing adaptations, and inferences that can be made from…

In the past, several latent structure models have been proposed for handling problems associated with measuring the achievement of examinees. Typically, however, these models describe a specific examinee in terms of an item domain or they describe a few items in terms of a population of examinees. In this paper, a model is proposed which allows a…

Examines the performance characteristics of 83 school-identified learning-disabled children on the Differential Ability Scales. Sixty percent showed a significant standard score discrepancy between the General Conceptual Ability and at least one achievement test. Implications regarding the educational diagnostic and intervention processes…

A detailed description of five latent structure models of achievement measurement is presented. The first project paper, by David L. McArthur, analyzes the history of mental testing to show how conventional item analysis procedures were developed, and how dissatisfaction with them has led to fragmentation. The range of distinct conceptual and…

Because testing, in many different forms, currently plays such an important role in education, Elementary Secondary Education Act, Title I, the Division of Federal Assistance in the Vermont State Department of Education, prepared this brochure to present a general introduction to terms and phrases commonly used in testing and to highlight some of…

This research program was designed to investigate the applications of item response theory and computerized adaptive testing to the unique problems of the measurement of ability and the measurement of achievement. The research utilized a combination of monte carlo simulation studies and live-testing studies. The research approach for adaptive…

To explain discrepancies in Utah's elementary school test results under the Elementary and Secondary Education Act's Title I Evaluation and Reporting System (TIERS), researchers investigated the adequacy and validity of TIERS evaluation models. Model A (norm-referenced testing) is used in most Utah school districts, in preference to Models B or C…

This study evaluates the effects of employing the linear, normalizing, and arcsine transformation methods for constructing scale scores on the Basic Competence Test (BCTEST). Tests in three subject areas (Chinese, English, and Mathematics) were studied using the data of test administrations from 2001 to 2003. The resulting scale scores for each…
