Optimal Stratification of Item Pools in a-Stratified Computerized Adaptive Testing.
Peer reviewed Peer reviewed
Chang, Hua-Hua; van der Linden, Wim J. – Applied Psychological Measurement, 2003
Developed a method based on 0-1 linear programming to stratify an item pool optimally for use in alpha-stratified adaptive testing. Applied the method to a previous item pool from the computerized adaptive test of the Graduate Record Examinations. Results show the new method performs well in practical situations. (SLD)

Alpha-Stratified Multistage Computerized Adaptive Testing with beta Blocking.
Peer reviewed Peer reviewed
Chang, Hua-Hua; Qian, Jiahe; Yang, Zhiliang – Applied Psychological Measurement, 2001
Proposed a refinement, based on the stratification of items developed by D. Weiss (1973), of the computerized adaptive testing item selection procedure of H. Chang and Z. Ying (1999). Simulation studies using an item bank from the Graduate Record Examination show the benefits of the new procedure. (SLD)
