Chittagong Grammar School (C.G.S.) was founded in 1992, to satisfy the need for a truly international school in Chittagong. The existing English-medium institutions were not of an international standard and many families were forced to send their school-going children overseas to seek a quality education. Four Chittagong families (Dadas, Ispahanis, Khans and Nizams) came together and co-opted the best teaching resources available in the city. These teaching consultants set criteria for standards and established school policies. The aim was to get the best teachers in Chittagong under one roof to create an institute of a high international academic standard.
