The purpose of this study was to construct a computerized adaptive test for junior high biology by applying item response theory. Five procedures were suggested for a successful application of latent trait theory in the computerized adaptive testing : (1) item banking and testing ; (2) test equating : (3) item response theory analysis : (4) the programming and procedures of computerized adaptive testing ; and (5) the evaluation of test validity. The item bank of the computerized adaptive test for junior high biology consisted of about a thousand valid items. More than three thousand samples in total were selected for item calibration. The parameters of item difficulty and item discrimination for each test were equated using anchor tests by regression methods. One-parameter tailored testing procedure was applied to the selection of next item tested and estimation of examinee’s latent trait. Classical test scores were compared with the latent trait of the computerized adaptive test for the validity. Test-retest correlation was analyzed for the test reliability. It is suggested that more criteria should be considered to validate computerized adaptive testing. In addition, two-parameter and three-parameter tailored testing procedures will be discussed in the near future.
