This study explored the utility, from a psychometric and cost effectiveness standpoint, of a computerized adaptive measurement system in an Air Force technical training environment. The phase 1 effort was designed to take the study to the point of producing an operational system ready to actually test technical training students adaptively. A literature review indicated that two testing techniques showed considerable promise: flexilevel testing and hierarchical testing; two courses were selected to implement these procedures. One preliminary conclusion was that adaptive testing appears to offer the potential for time savings of up to 50%. Furthermore, it was found that a very flexible computer system to drive the adaptive testing strategies could be relatively easily developed. (WH)
