Item Response Theory and Computer Adaptive Testing

Description:

A three-day course introducing you to Item Response Theory (IRT) and Computer Adaptive Testing (CAT) using the R open-source statistical computing software and Concerto, the open-source online adaptive test development platform. Get first-hand experience of applying IRT analysis to questionnaire data and create item banks suitable for computer adaptive testing. 

1. Introduction to R and RStudio
2. Basic concepts of Item Response Theory (IRT)
3. Generation of calibrated item banks using R packages
4. Simulating CATs to assess item bank performance
5. Scoring CATs using R
6. Administering CATs using Concerto  

Prior experience with R is not necessary. Participants should bring their own laptops with the latest version of R installed ( https://www.r-project.org/ ) and also RStudio (http://www.rstudio.com/ide/download/ )
