This research has focused on an application, in actual classroom practice, of computerised adaptive testing (CAT) in assessing learning achievement. The concept of CAT, an application of item response theory, has become feasible with the advent of high-speed computers. Basically, the testing in CAT is tailored to an examinee's ability level: the computer first obtains an estimate of the examinee's ability level based on his or her responses to initial test items, and then makes subsequent item-selection decisions that are most appropriate for measuring his/her performance level.
