The '70's
In 1971 there came a proposal to start a Christian school that would be housed in the Grace Baptist Church at 2216 Wilbraham Rd., with Rev. Howard Sears as Pastor. The proposal went before the church for a vote. It was approved and the doors were opened for Pre-School in March of 1972. In September, 1972, the doors were open to Kindergarten through 12th. The 1973 graduating class had 2 students. The church and school moved to the new property, at 3023 N. Union Rd., on July 8, 1973. The school was chartered by the state of Ohio. By the end of the decade a gym had been added to the building and boys' and girls' sports were in full operation.

The '80's
The school joined the Ohio Athletic Association. The site was prepared and a metal structure was purchased to house a new education building. Two graduates returned to the school as teachers. The first class of students to attend MCS from Kindergarten through 12th grade graduated.

The '90's
The first second generation student graduated. A new floor was added to the gym. The school's chapter of National Honor Society continued to grow. The baseball field was renovated. The Junior High moved to their own campus at Trinity Baptist Church. A track team was added. The "Millennial Vision" campaign was kicked off with three phases. First, to build a separate Daycare - Preschool facility to help free up space. Second, to renovate the preschool area to accommodate classrooms. Third, to complete the building on the hill to house all of Middletown Christian Schools.

The New Millennium
The Ethel P. Sears Pre-School & Daycare was dedicated on May 7, 2000. New classrooms were constructed in the wing that the preschool formerly occupied. The Middletown Christian Schools Foundation was set up to handle fund-raising efforts for the new building. A new building, consisting of the elementary wing, middle school wing, cafetorium, music room and office complex, was dedicated on August 14, 2002. The areas not scheduled to be completed were roughed-in and under roof. Record enrollments were reached with the opening of the state-of-the-art facility.
