# A Course on Test and Item Analyses

*2022-06-05*

# 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.

This course has been translated into Chinese at this link. The Chinese course uses traditional Chinese characters. If you open the website in Google Chrome, you can translate it into simplified Chinese.
