The goal of this project was to develop an inexpensive, self-contained system of hardware and software to support the development, administration, and evaluation of computerized adaptive tests. Toward that goal, commercial hardware was selected and a comprehensive software called the MicroCAT Testing System was developed. The MicroCAT system was…

To determine which produced the most accurate item parameter estimates, four methods of item response theory were evaluated: (1) heuristic estimates; (2) the ANCILLES program; (3) the LOGIST program; and (4) the ASCAL program. LOGIST and ASCAL produced estimates of superior and essentially equivalent accuracy. (SLD)

This paper explores the feasibility of developing a single-user microcomputer-based testing system. Testing literature was surveyed to discover types of test items that might be used in the system and to compile a list of strategies that such a system might use. Potential users were surveyed. Several were interviewed, and a questionnaire was…
