This study focused on ‘conflict resolution skills’, which is one of the core competencies, and critically reviewed how these skills are covered in the current Korean language curriculum. Furthermore, this study aimed to discuss how “conflict resolution education content” in Korean language education must be covered in preparation for the switch to a competency-based curriculum. To this end, this study first reconceptualized conflict resolution skills from the perspective of Korean language education as based on the core competences by OECD (2005) and studies on Korea language curriculums. This study reviewed conflict resolution education content currently included in the Korean language curriculum. The review revealed the following negative aspects: (1) the conflict resolution education content in the Korean language curriculum is concentrated in the stage of middle school; (2) conflict resolution content is mostly segmented into ‘conversation’, ‘discussion’, and ‘debate’; (3) there is redundant detailed content in the same learning stage; and (4) content elements related to conflict resolution skills are either insufficient or biased toward one side. Based on the above, this study provided implications of Korean language education for conflict resolution education in preparation for a change to a competency-based curriculum.
