Fundamentals of Item Response Theory (original) (raw)

AI-generated Abstract

In the last decade we have witnessed a revolution in educational and psychological measurement as the application of classical measurement theory has given way to the use of item response theory (IRT). Today, IRT is used commonly by the largest testing companies in the United States and Europe for design of tests, test assembly, test scaling anti calibration, construction of test item banks, investigations of test item bias, and other common procedures in the test development process. This book provides a lucid but rigorous introduction to the fundamental concepts of item response theory, followed by thorough and accessible descriptions of the application of IRT methods to problems in test construction, identification of potentially biased test items, test equating, and computerized-adaptive testing. A summary of new directions in IRT research and development completes the book.
