This workshop was delivered as a guest lecture to a graduate level psychometrics course and provided an introduction to using R for Item Response Theory (IRT). Students learned how to estimate IRT model with both dichotomous and polytomous item responses using the
mirt package. We also gave students the tools needed to explore and evaluate their estimated models. Along the way, we introduced several
tidyverse packages including
dplyr and
ggplot2.
