An educational assessment embodies an argument from a handful of observations of what students say, do or make in a handful of particular circumstances, to what they know or can do in what kinds of situations more broadly. This article discusses ways in which research into the nature and development of expertise can help assessment designers…

Recent advances in educational technologies and the wide-spread use of computers in schools have fueled innovations in test construction and analysis. As the measurement accuracy of a test depends on the quality of the items it includes, item selection procedures play a central role in this process. Mathematical programming and the item response…

U.S. state educational testing programs administer tests to track student progress and hold schools accountable for educational outcomes. Methods from item response theory, especially Rasch models, are usually used to equate different forms of a test. The most popular method for estimating Rasch models yields inconsistent estimates and relies on…

A widely used approach for categorizing the level of differential item functioning (DIF) in dichotomous items is the scheme proposed by Educational Testing Service (ETS) based on a transformation of the Mantel-Haeszel common odds ratio. In this article two classification schemes for DIF in polytomous items (referred to as the P1 and P2 schemes)…

This research involves an examination of the relationship between education and age on a wide array of neuropsychological test measures among patients diagnosed with Alzheimer's and vascular dementia. The purpose of this study was to investigate the role of education as an attenuating factor to neurocognitive decline in dementia. Although numerous…

There are many kinds of classroom assessment--from informal observation of students to more formal exams and standardized tests. Two categories have been identified--formative assessments and summative assessments. Formative assessments are used by teachers to provide feedback to students and to guide improvement of instruction. For example, if a…

In this study, we describe a framework for monitoring rater performance over time. We present several statistical indices to identify raters whose standards drift and explain how to use those indices operationally. To illustrate the use of the framework, we analyzed rating data from the 2002 Advanced Placement English Literature and Composition…

This paper examines the Programme for International Student Assessment (PISA), which has become a major and influential component of the Organisation for Economic Cooperation and Development's (OECD) educational work. This measure of comparative performance of educational systems of member and other nations is based on tests commissioned by the…

Assessment has long been at the center of education policy debates, and for good reason. The goal of schooling is to maximize student learning, and assessments provide a picture of what students know and are able to do. Assessments also have a strong influence on what goes on in classrooms. The United States is now poised to make the most dramatic…

A seven step strategy is presented for selecting a "good" test in an educational setting. The steps are as follows: (1) make the following preliminary decisions: (a) decide why you need to test, (b) decide what you intend to do with the results, (c) decide what practical decisions will be made based on the testing results, and (d) decide who will…

Author analogously applies to education some of the principles of science. (CB)

Describes the development of the International Guidelines for Test Use through the International Test Commission (ITC) project. These guidelines are designed to provide an international view of areas in which there is consensus on what constitutes good practice in testing. Describes why such guidelines are needed, and discusses their use. (SLD)

Reviews important milestones in the history of reliability, current issues related to reliability, and likely prospects for reliability from the perspective of what constitutes a replication of a measurement procedure. Pays special attention to the fixed/random aspects of facets that characterize replications. (SLD)

Developmental dyslexia is associated with functional abnormalities within reading areas of the brain. For some children diagnosed with dyslexia, phonologically based remediation programs appear to rehabilitate brain function in key reading areas (Shaywitz et al., Biological Psychiatry 55: 101-110, 2004; Simos et al., Neuroscience 58: 1203-1213,…
