The book answers practical questions about item response theory (IRT) in four sections: (1) an introduction to the concepts; (2) IRT theories and principles; (3) fundamentals of IRT; and (4) applications of IRT models. The book is useful for anyone trying to learn about IRT and how to use it. (SLD)

This book provides a historical overview of item-response theory (IRT) and contains a compendium of item-response-theory research. Each of its six sections deals with a unique application of a model or a family of models. Requires a strong psychometric background to understand some of the discussions. (SLD)

This book uses concepts familiar to those with a working knowledge of basic statistics and classical test theory to present item response theory models that are currently in wide use in both practical testing and research. The book would serve as a good entry-level graduate text in psychometrics and measurement methods. (SLD)

To provide an introduction to item-response theory (IRT) for individuals with modest statistical and mathematical skills, the book emphasizes a conceptual approach to understanding IRT concepts. The book fills the gap between mathematically detailed studies and summary chapters on IRT in general texts. (SLD)
