Abstract

An important component of both CAT and MST is the use of item response theory (IRT) as an underlying framework for item bank calibration, ability estimation, and item/module selection. In this chapter, we present a brief overview of this theory, by providing key information and introducing appropriate notation for use in subsequent chapters. Only topics and contents directly related to adaptive and multistage testing will be covered in this chapter; appropriate references for further reading are therefore also mentioned.
