This study compared the effectiveness of three procedures: constrained CAT, flexible modified constrained CAT,…

Lin, Chuan-Ju – Journal of Technology, Learning, and Assessment, 2008
The automated assembly of alternate test forms for online delivery provides an alternative to computer-administered, fixed test forms, or computerized-adaptive tests when a testing program migrates from paper/pencil testing to computer-based testing. The weighted deviations model (WDM) heuristic particularly promising for automated test assembly…

Vale, C. David; Gialluca, Kathleen A. – Applied Psychological Measurement, 1988
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)
