Bethel Christian School (BCS) is a Baptist Christian K-12 school in Lancaster, California. The school was established in 1979. At that time, the school, with 67 students and four teachers, used all of the facilities of the 4-acre (1.6 ha) church campus; the classrooms were initially located in Building 100. Building 200, the second phase of the school, was completed by September 1980. At that time the school had 150 students. The church and school purchased 5 acres (2.0 ha) of land adjacent to the original property, expanding the size of the property to 9 acres (3.6 ha). The church and school also acquired additional modular buildings, allowing expansion. The first senior class, consisting of six students, graduated in June 1989. In the 1990s BCS grew to well over 600 students.
