[en] The purpose of this talk is to briefly introduce the R package catR that permits random generation of response patterns under a computerized adaptive testing (CAT) framework. First, an outline of the CAT is proposed, with emphasis on the main concepts (item bank, ability estimation, next item selection, stopping rule, item exposure and content balancing). Then, the performance of the catR package is described by making connections between the general CAT framework and the functionalities of the R functions within catR. An example will be displayed, either as a “live” demonstration of catR or as part of the talk. Potential extensions of catR will also be discussed.
The catR package was jointly developed by Gilles Raîche (Université du Québec à Montréal, Canada).
