Item Response Theory

June 4, 2019

The purpose of this workshop is to provide a gentle introduction to unidimensional item response theory (IRT).  Specifically, we will discuss

  • IRT models that can be used to fit responses from dichotomous items
  • The use of the software package flexMIRT to estimate model parameters and how these results can be interpreted
  • Application of IRT in educational testing

Prerequisites: Individuals attending this workshop should have familiarity with basic inferential statistics and regression.
Materials: Participants are encouraged to bring a laptop with the trial version of flexMIRT software, which is available here:

 Instructor: Dr. Kyung Yong Kim is Assistant Professor in the Department of Educational Research Methodology. His research interests include item response theory models and their applications. More information can be found at
