This book develops an intuitive understanding of IRT principles through the use of graphical displays and analogies to familiar psychological principles. It surveys contemporary IRT models, estimation methods, and computer programs. Polytomous IRT models are given central coverage since many psychological tests use rating scales.

Ideal for clinical, industrial, counseling, educational, and behavioral medicine professionals and students familiar with classical testing principles, exposure to material covered in first-year graduate statistics courses is helpful. All symbols and equations are thoroughly explained verbally and graphically.


"It will be a useful book for a first course in IRT….a good book…for the working psychologist and the psychologist's mentor to share…"

Contemporary Psychology

"…useful to anyone wanting to learn how to use IRT or to teach a course on it…"

British Journal of Mathematical and Statistical Psychology

"…strongly recommended to psychologists interested in psychometric issues or researchers aiming to use this approach to analyze scales used in their own research."

Studia Psychologica

"…a thorough and comprehensive introduction to IRT and is a very useful reference book. It would be a helpful source to use when teaching students about IRT."
