Abstract  

Multidimensional computerized adaptive testing (MCAT) is based on the multidimensional item response theory and computerized adaptive testing. It can not only assess the examinees’ multidimensional ability, but also improve the measurement accuracy and test efficiency of cognitive diagnostic assessment. Hence, there will be a wild area for the application of MCAT. Based on the detailed introduction and evaluation of the MCAT which including the measurement model, the ability estimation method, the item selection methods and test stopping rule, some issues of MCAT which valued further research have been proposed.

Keywords multidimensional item response theory      computerized adaptive testing      ability estimation      item selection method      stopping rule
