Established in Karachi in 1978, The City School is today one of the largest private school networks in Pakistan with branches in all the major cities across the country. It currently has 185 schools in 52 cities with over 126,000 students in 458 owned and franchised schools. While its Head Office is in Lahore, its Regional Offices support a network of branches throughout Pakistan and overseas.

The City School continues to expand its reach to meet the demands for quality education. The knowledge and skills-based curriculum derived from the UK National Curriculum guides students from Nursery to Cambridge International Examinations (for 16 and 18 year age group), qualifying them for the IGCSE, and O and A Level examinations. The uniform implementation of the curriculum gives parents, students, and teachers the advantage of a smooth and efficient transfer from one school to another within the system.
