This research aimed at 1) revealing the background of the multicultural education management (MEM) program and the process of developing multicultural education, 2) determining the MEM program's success at SMP/MTs in Bali Province, and 3) identifying the challenges of MEM program implementation. The researcher did the study at SMP/MTs in Bali Province by using a mixed-method approach. The researcher used a qualitative approach to identify the background and the process of MEM program development. Simultaneously, a quantitative approach with the Content Input Process Product (CIPP) evaluation model was done to determine the MEM program's success. The results of the study reveal that the MEM program's background consists of historical, philosophical, juridical, sociological, geographical, and futuristic backgrounds, and the development process of the MEM program was created through three different forms: the idea, concept, value, and norm; multicultural activity; and students' real act. The evaluation using the CIPP evaluation model determines that the MEM is highly successful. While the challenges faced on the implementation of MEM program, namely: lack of contribution from the society, socio-economic problems, lack of stakeholders understanding on the mission of MEM program, lack of infrastructure, lack of collaboration and participation, and low non-academic achievement.
