Item Response Theory in R with {mirt}

In this talk, Henrik presented a statistical paradigm called Item Response Theory (IRT). IRT is the preferred statistical framework for modelling educational and psychological scales. In education, IRT is the statistical method used in international assessment programs like PISA and national assessments such as the national tests in Norway. The talk will focus on applications of IRT, specifically making results on different tests comparable and the fairness of educational tests. Henrik Galligani Ræder is a doctoral research fellow at the Centre for Educational Measurement at the University in Oslo (CEMO), Norway. His research focuses on the Norwegian national assessments, vertical scaling of educational tests and the numeracy proficiency of Norwegian students.
