Granger Christian School was established in 1972 as an elementary and junior high school ministry of Grace Church.  Over the next two years, the high school grades were added.  GCS continues as a vital ministry of Grace Church.

For the first 25 years of existence, the school was housed in a church building on the north side of South Bend.  In 1992, God provided the property to build a new church facility in the heart of the fast-growing community of Granger, Indiana.  The year 1997 brought about a name change when Grace Baptist School became Granger Christian School in a effort to reflect a redirection in the philosophy of the school.  This new direction included the desire for a broader appeal in the community and a commitment to expand educational and extracurricular opportunities.

Today, Granger Christian is a growing PreK through twelfth grade school providing an academically challenging program in a spiritually nurturing environment.
Granger Christian School meets the current graduation requirements of the State of Indiana.  GCS is a member of the Association of Christian Schools International (ACSI), earning their accreditation status in the spring of 2010.  ACSI is the largest accrediting association of Christian Schools in the world.
