An Investigation of Procedures for Computerized Adaptive Testing Using the Successive Intervals Rasch Model.

Koch, William R.; Dodd, Barbara G.

Educational and Psychological Measurement, v55 n6 p976-90 Dec 1995

Basic procedures for performing computerized adaptive testing based on the successive intervals (SI) Rasch model were evaluated. The SI model was applied to simulated and real attitude data sets. Item pools as small as 30 items performed well, and the model appeared practical for Likert-type data. (SLD)
