The school began as the vision of missionaries to give their children a Christian education and to prepare them for the world. In the fall of 1981, the school began in a small, rented house as Central Java Inter-Mission School. The school had fifteen students and three teachers. Soon the number of students grew, and the originally rented house grew crowded. The school relocated to another house in a village area. When the school was moved, the original house was refurbished as the first dormitory. More teachers and even more students came from many nations. By 1986, the second school building had also become insufficient for the increasing student population. A high school facility was built on a piece of rented land not far from the second school building. The elementary remained in the second school for a time, but two years later a large plot of land was purchased by the organizing foundation and a new elementary school was built to accommodate the increasing number of students and staff. The second school building became a second dormitory. The new school campus was opened in 1990. Since 1990, there has been continual construction on the campus, which has expanded to. The land was cleared and four dorms, a high school, a soccer field and track, an auditorium, a lunch pavilion, more elementary buildings, and a two-court gym have been built. In October 2001, 144 students and 60 teachers with American nationality were dismissed after anti-American protests. In 2002, the name of the school was changed to Mountainview International Christian School. In January 2015, the name of the school was changed to Mountainview Christian School from the previous Mountainview International Christian School
