Roy Levy


I am an Associate Professor in the T. Denny Sanford School of Social & Family Dynamics at Arizona State University, specializing in Measurement and Statistical Analysis. My research and teaching interests include methodological investigations and applications in psychometrics and statistical modeling, focusing on item response theory, structural equation modeling, and Bayesian approaches to inference and modeling. I also work in areas of assessment design, focusing on evidentiary principles and applications in simulation-based assessments. Here you can find information on my courses, papers and software, and information on my book with Bob Mislevy, Bayesian Psychometric Modeling.
