| Outline of Final Research Achievements |
Adaptive testing is a question format of computer testing that estimates an examinee’s ability sequentially and which selects question items with the highest estimation accuracy according to the examinee’s ability. However, in conventional adaptive tests, it is highly likely that the exact same group of items will be selected for examinees who have equivalent ability. We propose a uniform adaptive test that adaptively selects different items for examinees even if those with equivalent capabilities, maintaining the same evaluation accuracy. Specifically, we follow the procedure outlined below. 1) We compose an item cluster for a multiple equivalent test based on the amount of test information. 2) Regarding an item cluster for a multiple equivalent test as an item bank, we propose a uniform adaptive test that estimates the value of an examinee’s ability sequentially and which selects items with the highest estimation accuracy.
