# A Course on Test and Item Analyses

*2021-12-15*

# Summary of the Course

This course will have a practical focus on how to carry out test and item analyses. Both classical test theory (CTT) and item response theory (IRT) will be taught. Example code snippets in R will be provided to run the analyses. We will use *Educational Measurement for Applied Researchers: Theory into Practice* (Wu, Tam, and Jen 2016) as a reference book. We will use the R **CTT** package (Willse 2018) and R **TAM** package (Robitzsch, Kiefer, and Wu 2021) for most of our analyses.

This website will be updated each week to include materials for the new sessions.
