Kingsbury, G. Gage; Houser, Ronald L. – Educational Measurement: Issues and Practice, 1993
The utility of item response theory (IRT) models in computerized adaptive tests is considered. Measurement questions that have been answered using IRT, and those that might be overlooked because of IRT, are reviewed. Areas in which fuller use of IRT could improve adaptive testing practices are identified. (SLD)

Legg, Sue M.; Buhr, Dianne C. – Educational Measurement: Issues and Practice, 1992
Three computerized adaptive tests (CATs) in mathematics, reading, and writing were administered to 628 community college students to determine whether examinees of different ethnic, gender, ability, and age groups, and computer experience were differentially affected. Some differences exist; however, they do not preclude use of CATs. (SLD)
