represents a relatively new but rapidly evolving research area where cognitive theories, computer technologies, and psychometric practices are used to generate items. In its most ambitious form, AIG can be described as the process of using models to generate statistically calibrated items with the aid of computer technology. Significant developments in AIG(More)

Computerized multistage testing (MST) designs require sets of test questions (testlets) to be assembled to meet strict, often competing criteria. Rules that govern testlet assembly may dictate the number of questions on a particular subject or may describe desirable statistical properties for the test, such as measurement precision. In an MST design,(More)
