Handbook of Polytomous Item Response Theory Models

"I am excited to share this book with graduate students and fellow IRT researchers. ... There is a lot of rich information in here that helps even seasoned IRT researchers develop a greater appreciation and understanding. ... It is one of the most useful measurement-related edited volumes that I have read and I will be referring to this book for years to come." - Michael Zickar, Bowling Green State University, USA, in The American Statistician

"This really is a ‘must read’ for measurement students and specialists alike. An outstanding group of authors explain the models, clarify misconceptions, and offer new historical material, methods for evaluating model fit, and innovative applications." - Edward Haertel, Stanford University, USA

"It will likely become a standard reference on polytomous IRT analyses ...I would definitely buy it and recommend it. I would most likely use it for an advanced IRT course." - Mark D. Reckase, Michigan State University, USA

" I expect this book will quickly become a seminal resource for researchers and practitioners... it will ... have a large impact on the measurement community... Nering and Ostini have put together a very impressive group of experts in the area of polytomous IRT modeling. ... This book fills a big gap ... I would certainly purchase the book and use it in teaching my advanced IRT classes." - Terry Ackerman, University of North Carolina, Greensboro, USA

"An outstanding collection of original chapters by the principal developers of polytomous IRT models, supplemented by important contributions on model evaluation and example applications. This book will be a standard reference on these models for years to come." - David J. Weiss, Professor of Psychology, University of Minnesota, USA
