Computerized test construction

This article starts with a brief introduction to the area of computerized test construction. In the first section, the problem is formally stated as an optimization problem, with an objective function, for example, that maximizes the amount of information in the test or minimizes the amount of items in a test. In the second section, an overview is given of the methods that are available for computerized test construction. In sections computerized construction of linear test forms, construction of computerized adaptive tests, and construction of multistage tests, some specific issues related to the three most important test forms are discussed. The article ends with a discussion on one of the recent issues in computerized test construction, the problem of uncertainty in some of the parameters during optimization.
