The purpose of this study is to analyze the process and cause of policy conflicts between teachers and parents on the college admission system, and then propose ways to ease conflicts based on this. The study target period was the policy conflicts between the Park Geun-hye administration and the Moon Jae-in administration. In order to achieve the research purpose, the process of policy conflict was analyzed by dividing it into conflict occurrence stage, conflict amplification stage, and conflict mitigation stage. To analyze the causes of policy conflicts, the perceptual, structural, and political aspects were analyzed. As a result of the analysis, the process of policy conflicts between teachers and parents began to occur during the Park Geun-hye administration, and the conflict was amplified in the Moon Jae-in administration, but the conflict is now being mitigated. The key issue of the policy conflict was the ratio between the occasional student record comprehensive entrance exam and the regular entrance exam. The causes of the policy conflicts were differences in the perception of the college entrance system between teachers and parents, the characteristics of the group structure and the lack of higher education laws, and the government s inadequate efforts to mitigate policy conflicts. Based on these analysis results, this study proposes ways to improve awareness, structure, and politics to resolve policy conflicts.
