The background of this research is the granting of broad educational autonomy to schools, which is a big concern for the government of Indonesia. School-based Management (SBM) appears as an alternative to the new paradigm of education management offered. One of the characteristics of SBM is inseparable from the participation of the community. School Committee is a forum for parents, communities, stakeholders, and entrepreneurs in school development and can bridge the interests of all the parties. To date, not many School Committees have been able to play an effective role in supporting the implementation of education in schools. One of the contributing factors is that the institutional design is not seriously empowered into an independent and professional institution. This study aimed to examine the effectiveness of school committees in school-based quality improvement management. The study method is qualitative descriptive. Data were collected through interviews, observation, and documentation. Validation of the collected data was done through triangulation techniques. The results showed that thematically the author underlined four important things, namely: first, the school committee has effectiveness as a consideration partner, material support, financial, thought and energy, and learning mediator; second, quality improvement strategies can be achieved through efforts to improve school subject competence and involvement in competitions; third, to measure the results of achievements, an education quality management audit is carried out, and; fourth, the budget as one of the determining factors in achieving school goals and objectives must be optimized by utilizing the flexibility of implementing Law No. 23 of 2014 and optimizing available resources. This research has implications for considerations in the preparation of internal school strategies to prioritize school needs and recommendations related to budget policies and inventory of school components.
