International Classification:
G09B 7/00
Abstract:
An improved method is provided for maximizing accuracy of ability estimates while permitting a test taker to review and/or change responses in computer adaptive testing. One or more ability-dependent items are selected from a pool of adaptive items, the selected ability-dependent item matching interim ability estimates for an examinee. One or more ability-independent items are selected from a pool of non-adaptive items. The interim ability estimate can be generated after each iteration of responses to ability-dependent and/or ability-independent items. The ability-independent items can be randomly dispersed throughout the computer adaptive test. A prescribed ratio can be maintained between the ability-dependent items and ability-independent items for minimizing overestimation of the examinee's ability scores after reviewing and changing one or more test items in the computer adaptive test. Alternatively, ability-independent items can be selected after an incorrect response to an ability-dependent or ability-independent item at a predefined test item location.
