Official involvement of parents in school education has been very limited until recently within the highly centralized educational administration and school management system in Korea. But, the educational reform in 1995 has brought fundamental changes in educational administration and school management system of Korea. The main approach of the reform is decentralization, which tries to turn over the power of the central government in educational administration and school management to the hands of regional education offices and site schools. According to the reform, the school council was introduced to enforce autonomous and responsible school-based management through broad participation of various stakeholders of education. In this article, I examined the background, roles, and characteristics of the school council, focusing on the new pattern of parent-school participation formation. And based on the findings, I discussed the issues of parents' participation and future prospects of the school council and suggested policy implications for better implementation of parent-school partnership through the school council.
