This study is a conceptual and analytical research for realization of evaluating literary competency. The point of issues are that hardly any assessment for `competency` was made in the classroom for literary education and that at the bottom of the fact theories for literary education has failed hierarchic conceptualization of literary competency. In this study I raised a question whether the developmental gradation for literary competency is possible or not, and inquired how we can evaluate if possible (theorically), or how we get the favorable condition of actualization if possible (practically).
