Grange School was founded in 1958 by a group of British expatriates, to provide education of equivalent standard to that which obtains in the UK.

Both exams are under the auspices of the University of Cambridge Local Examination Syndicate (UCLES).

Grange School's population is projected as 430 girls and boys in the Primary Section which is from Reception class to Year 6, between the ages of 4+ and 11.

The school encourages students to participate in charity events as well as other extra-curricular activities such as chess, arts and crafts, swimming, tennis, football, and basketball.
