Item Response Theory II

3 credits · Graduate School

Item Response Theory (IRT) II covers IRT models commonly used in education and psychology and their parameter estimation techniques using currently available software. This course will focus on developing a conceptual understanding of the mathematical concepts underlying the IRT models in so far as this is necessary for appropriate use of IRT models. In addition, the class covers topics in applications of IRT including equating/linking (as preliminary procedures for complex IRT models) and differential item functioning (DIF) analysis. [3]
