Overview of Adaptive Testing, briefly discuss the important concepts associated with CATs and MSTs. We then introduce the R open source software packages . and . for CAT and MST simulations, and provide examples on how to use . and . for simulations.

Examples of Simulations Using ,In this chapter, we present several examples of using the R package . which is similar to CAT but specific for MST. We then implement a study with several MST designs, and an empirical comparison of MST versus CAT.
