A substantial amount of research has been conducted over the past 40 years on technical aspects of computerized adaptive testing (CAT), such as item selection algorithms, item exposure controls, and termination criteria. However, there is little literature providing practical guidance on the development of a CAT. This paper seeks to collate some…

Provides an overview of computerized adaptive testing (CAT) and introduces contributions to this special issue. CAT elements discussed include item selection, estimation of the latent trait, item exposure, measurement precision, and item-bank development. (SLD)

Educational item banking presents observers with a considerable paradox. The development of test items from scratch is viewed as wasteful, a luxury in times of declining resources. On the other hand, item banking has failed to become a mature technology despite large amounts of money and the efforts of talented professionals. The question of which…

Three major pragmatic issues in computerized testing are addressed: (1) encouraging teacher use; (2) reporting of information; and (3) test construction. Reference is made to four related articles. Additional areas for research include reporting of test information; item bank standards; validity; and rules for stopping in computerized testing.…

In an adaptive test, the test administrator chooses test items sequentially during the test, in such a way as to adapt test difficulty to examinee ability as shown during testing. An effectively designed adaptive test can resolve the dilemma inherent in conventional test design. By tailoring tests to individuals, the adaptive test can…

This discussion of computer-assisted repeatable tests, which are frequently used to evaluate and monitor students' acquisition of knowledge in mastery learning situations, cites and describes a number of specific examples of systems for creating both online and batch tests. A reference list is provided. (JJD)

Some software packages currently available for item writing and item banking are reviewed. Eleven test-generation and three item-banking packages are listed. Users trained in item response theory can find a great deal of power in a desk-top system. (SLD)

The advent of computers in educational and psychological measurement has lead to the need for algorithms for optimal assembly of tests from item banks. This paper reviews the literature on optimal test assembly and introduces the contributions to this report on the topic. Four different approaches to computerized test assembly are discussed:…

Computerized adaptive testing (CAT) has become increasingly common in large-scale testing programs. This paper considers relevant practical issues that are likely to be faced by the developers and managers of a CAT program. The first cluster of issues is that of item pool development and maintenance. It includes such considerations as item pool…

Computer adaptive testing systems are feasible for certification and licensure testing. This is in part due to the availability of extensive yet inexpensive computers. Modern item response theory, combined with computerized adaptive testing, yields a powerful new method of testing which provides greater accuracy and efficiency and less boredom for…
