In many high-stakes testing programs, testlets are used to increase efficiency. Since responses to items belonging to the same testlet not only depend on the latent ability but also on correct reading, understanding, and interpretation of the stimulus, the assumption of local independence does not hold. Testlet response theory (TRT) models have been developed to deal with this dependency. For b...

This study used principles underlying item generation theory to posit competing perspectives about which features of situational judgment tests might enhance or impede consistent measurement across repeat test administrations. This led to 3 alternate-form development approaches (random assignment, incident isomorphism, and item isomorphism). The effects of these approaches on alternate-form con...

In this study we consider the efficacy of a relatively new and widely accepted certification system for teachers established by the National Board for Professional Teaching Standards (NBPTS). To address the limitations in past research on the subject, we utilize a unique database covering the universe of teachers and students in Florida for a four-year span to determine the relationship between...

equating test scores is an important issue in large scale testing. almost all standardized tests have several forms which vary in difficulty. new forms are written and added every year. when the items in different forms of a test vary in difficulty, direct comparison of test-takers who have taken different forms and are at the same ability level is not possible; hence, the issue of test fairnes...

University researchers and teacher facilitators implemented a state-funded professional development project during the 2005-06 academic year to help county middle school teachers improve student achievement in mathematics. In this paper, we discuss lessons and results from this innovative model, whose iterative cycle includes teacher content knowledge, item analysis from a high-stakes test, ped...

Abstract Several papers have challenged the robustness of loss aversion, claiming that it is context-dependent and disappears for small stakes. These use a behavioral definition aversion may be confounded by diminishing sensitivity probability/event weighting under new version prospect theory (PT). We perform theory-based test controls these confounds. found significant both stakes high The ove...
