The school initially started in Green Valley in the houses of Mr. James Swynenberg and Col. U. Sherring on 10th July 1990. On July 11th 1994, the school shifted to the present address. Classes were held in temporary sheds. The year 1993, saw the birth of Grace Childrens' Residence with seven children in it. By the end of 1997, the main buildings were completed. The office and some classes shifted to the new building, and the school received composite affiliation to CBSE. The year 1999, saw the first batch of class X students appearing for board exams. They all passed with flying colors. The first batch of class XII also passed in March 2002 with flying colors. The first phase of Grace came to an end, when Dr. David G. Fiol, the Founding Principal, handed over charge to his successor, Mr. Benjamin Newton on 1st April 2000. One cannot forget the grace of God and the tireless efforts of all the society members who sacrificed their time for bringing this school to where it stands. The school has over the period been growing and the Lord has been blessing it. From 1990 up to today it humbly acknowledges the blessing and grace of the Almighty God.
