In this digital ITEMS module, Dr. Roy Levy describes Bayesian approaches to psychometric modeling. He discusses how Bayesian inference is a mechanism for reasoning in a probability-modeling framework and is well-suited to core problems in educational measurement: reasoning from student performances on an assessment to make inferences about their…

Drawing upon his experience, more than 60 years ago, as a psychometric support person to a very special teacher of brain damaged children, the author of this article reflects on the productive use of educational assessments and data from them to educate - assessment in the service of learning. Findings from the Gordon Commission on the Future of…

In this commentary, we summarize some of the main themes of the NRC report and note ways in which the papers by Mislevy and Haertel, Gorin, and Abedi and Gandara address the Panel's recommendations. We then briefly review and offer reflections on each paper. We see much to applaud here and also in the broader effort to build bridges between the…

This article presents the viewpoint that care must be taken to fit the specifics of a testing program to its intended purpose. Testing for diagnosing individual student learning and for school evaluation should not be confused. Statewide testing programs may provide evaluative information, but are inadequate sources of diagnostic information. (LMO)

The use of performance assessments in accountability programs is discussed. Performance assessments have the potential to measure important objectives not easily measured by multiple-choice tests. Nevertheless, they are not suitable for every purpose, and their use should not be oversold. Many psychometric issues remain to be resolved. (SLD)

Implications of using alternative assessments for accountability in a high-stakes testing environment (using tests to make impact decisions for students, schools, or teachers) are examined. The psychometric properties of standardized alternative assessments are discussed, and the consequences of their use are considered. (SLD)
