Proposed and evaluated a modified version of the maximum Fisher information (MFI) criterion called the nearest-neighbors (NN) criterion. Simulation study results show that NN procedure improved to a moderate extent the undesirable item exposure rates associated with the MFI criterion and keeps sufficient precision in theta estimates.

Peer reviewedCheng, Philip E.; Liou, Michelle – Applied Psychological Measurement, 2000
Reviewed methods of estimating theta suitable for computerized adaptive testing (CAT) and discussed the differences between Fisher and Kullback-Leibler information criteria for selecting items. Examined the accuracy of different CAT algorithms using samples from the National Assessment of Educational Progress. Results show when correcting for…
