|This paper discusses whether the poetry will be fit for the learners of the relevant grade. using works of Korea`s representative poets in revised Korean language and literature text books as materials. The works that this paper mentioned have corners yet to be suitable for intellectual capacity or interest of learners. Composing works that are appropriate for learners should be followed by the work which includes the expressive and semantic aspects of poetry. Students avoid the works which are far from their life experience or abstract and ideal. Not only the quantity or quality of indirect expression but also the familiarity with the content of work influences the level of difficulty. When ranks of poetry in textbooks are decided, expected difficulty level should be estimated considering the development characteristics of learners. A poetry selector estimates the level of poetry on the basis of the degree of indirect expression, the degree of omission, the frequency of strange words, etc. and then decides ranks suitable for the level of learners. For lower graders in middle schools, the works whose meanings are clear and whose degree of implication is low should be selected. Though indirect expression appears partially, the works easy to understand should be applied to second graders of middle school, and the works requiring a considerable reasoning process to at least middle school third graders. The works to be interpreted from various angles are efficient when they are dealt with in the course of high school whose students` critical thoughts are remarkable.
