Item Response Theory (IRT) is used to analyse response data at item level. It is a statistical process for estimating characteristics of items and examinees and defining how these characteristics interact in describing item and test performance. When used properly IRT can increase the efficiency of the testing process, enhance the information provided by that process, and make detailed predictions about unobserved testing situations.
