ABSTRACT
Cognitive diagnostic assessment has become a promising field of psychometric research over the past several years. Instead of providing a summative score, cognitive diagnostic assessment feed diagnostic information back to each examinee. In addition, cognitive diagnostic assessment specifies the attributes and skills mastered by the students, as well as the areas on which remedial instruction is needed (Leighton & Gierl, 2007). Therefore, cognitive diagnostic test is not only used for the purpose of evaluation, but also for providing detailed and valuable information regarding each student's strengths and weaknesses in learning.
