PRACTICAL ISSUES IN LARGE-SCALE COMPUTERIZED ADAPTIVE TESTING

Computerized adaptive testing, although well-grounded in psychometric theory, has had few large-scale applications in the past. This is now changing because the cost of computing has declined rapidly. As is alw ays true at such junctures where theory is translated into practice, m any practical issues arise that must now be addressed. In this article , we discuss a number of such issues and sketch out potential problems and potential solutions. Our purpose is to encourage further developm ent of solutions to the issues presented as well as other practical is sues facing measurement professionals involved with the implementation of adaptive testing.
