Computerized adaptive testing is a very effective mode in e-testing. It can shorten the time in providing accurate estimate of student ability. In this paper, we will introduce a new item selection method that would allow more flexibility in balancing the two competitive goals of accuracy and item pool utilization in computerized adaptive testing. Moreover, an index for comparing a weighted balance of these two goals is proposed.
