Research dealing with the administration of tests via computer is reviewed. Several issues related to computerized testing are discussed, and areas in need of additional research are identified. The focus is on education-related ability and achievement testing; psychological tests and computer-based simulations are not addressed. (SLD)

The development of a hypothetical testing program designed to provide optimum information about student achievement is chronicled. Computer adaptive testing and performance testing are postulated as part of the program. What optimum information really means is discussed. Optimum is only optimal when theory and application are balanced. (SLD)
