UV9250 – Equating test scores with IRT techniques
In many applications of testing there is a need to have different versions of a test which provide scores on the same scale. Many different techniques of test equating have been developed, and the course focuses on the versatile and powerful techniques developed within the framework of item response theory (IRT), with a special focus on the Rasch model, and extensions of this model. The course first introduces the basic principles of IRT, including model specification, estimation of item and person parameters, and testing of model fit. Different designs of test linking and equating are then discussed from methodological and practical points of view. In the final part of the course several examples of designs for test equating are presented and discussed, and participants carry out hands-on exercises.
- Basic principles of IRT, including model specification, estimation of item and person parameters, and testing of model fit.
