Colonial Christian School operates as a non-profit ministry of Colonial Hills Baptist Church to assist families as they educate children in the truth that God has revealed. Colonial Christian School (CCS) opened its doors in the fall of 1976 under the direction of Dr. Wendell Heller and Dr. Richard Hand as a ministry of Northeast Baptist Church. The name of the church was later changed to Colonial Hills Baptist Church. The school started in the present-day Youth Center with preschool and kindergarten classes. In the fall of 1977, the school moved across the road into the A-wing rooms of a new building and began adding grade levels each year. In 1982, the school moved into the B-wing classrooms and added grades 9-12. In 1998 the Heller Building was completed to help meet the growing programs and academic needs of the church and school.
Colonial Christian School is a college-preparatory school which challenges students to use the knowledge, talents, and abilities that God has given them to glorify Him. CCS is an active member of the Indiana Association of Christian Schools (IACS) and the American Association of Christian Schools (AACS). CCS was granted full accredition status by the American Association of Christian Schools in June, 2013.
