The Chittagong Grammar School (CGS) was founded in 1992, to satisfy the need for an international school in Chittagong.
A derelict building on Sarson Road was renovated and refurbished to house the school which opened in January 1993. There were only five classes - 5 to 9, 64 students and 14 teachers. Enrollment commenced in October/November 1992 and classes began on 12 January 1993.
The range of classes was expanded and by 1996 the entire range of classes (Playgroup to 'O' Levels) was being offered. Later the same year, the academic year of the school was changed from January - December to a September - June session.
In September 1996, CGS relocated and moved the Junior Section (Playgroup- Class 3) to its new premises.
In addition to Round Square, CGS is a member of several other international organizations, including a College Board Center (SAT tests), Duke of Edinburgh's Award Scheme (DOE), International School Services (ISS), Harvard University Model United Nations (MUN) and an international Fellowship Centre for Cambridge International Examinations (CIE).
