dc.description.abstractThe purpose of this study was to develop a calibrated item bank in computerized adaptive test for measuring students’ performance in mathematics. The standard performnce for cat was also determined and the characteristics of cat based on arcs model were examined. This study was conducted in four stages including (1) developing an item bank, (2) developing a cat, (3) setting a performance standard and (4) analysing arcs model. Rasch measurement model was used in the development of item bank where 600 mathematics item were calibrated using concurrent comment item equating method. A total of 334 items were found fulfilled the psychometrics properties in developing an item bank for cat. The item difficulty for the items was used as item parameter in developing a cat on platform in the second stage. The cat was developed on concerto platform and adminitered to 381 secondary students from 6 schools. The students’ mathematics performance was analysed based on the recommended cutscores obtained in stage three. In stage three, the recommended cutscores for mathematics performance using cat was acquired from a standard setting study using bookmark method. Four performance levels, namely, below basic, basic, proficent and advanced level was yielded from three recommended cutscores.
