This course provides an in-depth understanding of a wide range of item repose theory (IRT) models such as dichotomous models, nominal and ordinal models, multidimensional and multicomponent models, models for response times, nonparametric models, models for nonmonotone items, hierarchical response models, and generalized models. The course also thoroughly reviews several applications of IRT to the daily practice of testing. In addition, the course offers a critical discussion of how IRT has advanced areas such as large-scale educational assessments, psychological testing, cognitive diagnosis, or the more general area of measurement of change.
