Practical Questions in Introducing Computerized Adaptive Testing for K-12 Assessments

In this paper, a number of practical questions related to introducing CAT for K-12 assessments are discussed. These questions relate to four main topic areas: 1) the CAT algorithm; 2) CAT item development; 3) the CAT test delivery system; and 4) psychometrics to support CAT. In considering these questions, we describe some of the successful practices that have been used in operational highstakes CAT programs, as well as the challenges these programs face. This discussion is aimed to assist state departments of education in considering the use of CAT as they move to transition testing programs to online delivery in the future.
