The purpose of this study is to analyze the characteristics of the Korean language curriculum through curriculum content mapping (CCM) in the OECD Education 2030 project, which is later compared with the international curricular of the national languages. The CCM framework consists of a “competency code” that presents OECD competencies and a “content code” that contains the content of the curriculum. In this study, the degree of the competencies in the Korean language curriculum is analyzed and compared with the international curricular in terms of the OECD perspective. The result is analyzed as follows. First, foundational literacies of Korean were similar to the international national language curricular. Second, in the competencies of skills, attitudes and values, “problem-solving” and “learning about learning” were higher in the Korean language curriculum than the OECD average, “critic thinking” was similar to, and “persistence” was lower than the OECD average. Third, in terms of key concepts, both “student agency” and “co-agency” were higher in the Korean language curriculum. Fourth, “creating values” and “solving dilemmas” in terms of the degree of reflection of CCM framework competency related to transformational competencies, the Korean Language was higher than the average of OECD member countries in terms of “creating new values” and “resolving tensions and dilemmas” were higher but “taking responsibilities” were lower than the OECD countries. Fifth, the competencies in the compound literacies were also compared. These comparison results provide as reference materials that describes the suitability of the Korean language curriculum and contributes to future revisions of the Korean language curriculum for the students in 2030s.
