Title: Computerized Adaptive Testing with \proglang{R}: Recent Updates of the Package \pkg{catR}
Abstract: The purpose of this paper is to list the recent updates of the \proglang{R} package \pkg{catR}. This package allows for generating response patterns under a computerized adaptive testing (CAT) framework with underlying item response theory (IRT) models. Among the most important updates, well-known polytomous IRT models are now supported by \pkg{catR}; several item selection rules have been added; and it is now possible to perform post-hoc simulations. Some functions were also rewritten or withdrawn to improve the usefulness and performances of the package.
