This excessive expansion of private education has not only altered the allocation of educational resources but also significantly undermined the authority, fairness, and quality improvement of public education. By analyzing the specific causes of this overheating in the Republic of Korea private education, this paper systematically examines its impacts on various aspects of public education and proposes targeted solutions. The study aims to provide insights into understanding the challenges within the Republic of Korea's education system and exploring optimization pathways, ultimately contributing to the development of a more balanced and sustainable educational model.
