Computerized adaptive and multistage testing with R

The goal of this workshop is to provide a practical (and brief) overview of the theory on computerized adaptive testing (CAT) and multistage testing (MST), and illustrate the methodologies and applications using R open source language and several data examples. The implementations rely on the R packages catR and mstR that have been already or are being developed and include some of the newest research algorithms developed by the authors. This workshop will cover several topics: the basics of R, theoretical overview of CAT and MST, CAT and MST designs, assembly methodologies, catR and mstR packages, simulations and applications. The intended audience for the workshop is undergraduate/graduate students, faculty, researchers, practitioners at testing institutions, and anyone in psychometrics, measurement, education, psychology and other fields who is interested in computerized adaptive and multistage testing, especially in practical implementations of simulation using R.
