Abstract : The design of a Computerized Adaptive Testing (CAT) system requires the careful integration of psychometric and engineering developments. System designers must be cognizant of the relationships among the psychometric components of the system, among the physical components of the system, and between its psychometric and physical components. A hierarchical functional design model has been developed to facilitate the design of a prototype CAT system for DoD enlisted personnel accessions testing. The model addresses both the psychometric and administrative/operational requirements of the system and serves as the blueprint for translating these functional requirements into a working prototype. The focus on function in this design approach insures that the description of CAT psychometric procedures, in terms of system functions, precedes specification of the physical elements of the system through which these procedures are implemented. Such precedence is critical to the psychometric integrity of the system development effort.
