In the summer of 1997, a small group of Mt. Bethel Church members were commissioned to analyze the interest and demand throughout our community for Christ-centered education for our children. For over 20 years, Mt. Bethel had offered one of East Cobb's most respected preschools. The possibility of continuing that tradition of Christ-centered excellence with lower, middle and upper school students was the focus of the committee's analysis. The conclusion was the demand for quality Christian education far exceeded the supply of available options for parents, particularly in the immediate area. On August 21, 1998, the Academy opened with two kindergarten classes. In 2014, MBCA purchased and renovated a 34-acre property six miles from the Lower Roswell Campus to fulfill the long-awaited vision of building a high school. In August of that year, the Academy's Upper School welcomed its first class of ninth graders. The Academy now serves over 690 students in Junior Kindergarten-12th Grade.
The Academy enjoys full dual accreditation through the Southern Association of Independent Schools (SAIS) and Southern Association of Colleges and Schools (SACS).
