One of the chronic problems of literary ability assessment in NAEA is that the assessment should answer every need for the necessary condition demanded in a large-scale standardization test, the formal suitability demanded in Korean subject assessment, and substantial suitability demanded in evaluation of literary ability. This problem means that generally, these three demands are certain to contradict each other. In this situation evaluation of literary ability would be impossible. Through investigating the execution of NAEA-especially Korean subject assessment tool based on CRE 2010-7 of KICE-I confirmed that this tool, using a total number survey and non-execution assessment, would not suitably function as an evaluation & verification device on literary ability. Furthermore, I ascertained that this tool could not make a coherent explanation on achievement or development of literary ability of students. As alternatives, I suggested executing literary ability assessment in NAEA as a sample survey, accepting a qualitative test, increasing the number of questions, and moreover developing the assessment tool to help verify the qualitative standard of comprehension and acceptance of literary experience in this study.
