OUR HISTORY
Global International Schools was founded by Mrs Abolaji Osime in 1999. It began as an independent Sixth Form College in Ikoyi, Lagos. Since then, the school has expanded its educational offerings.
By 2005, the college had built a strong reputation for A-Level, IGCSE and degree foundation programmes. These programmes helped students pursue university education in the United Kingdom, Europe and the United States. Later, the institution expanded to Abuja. It also introduced a Canadian foundation pathway for students seeking admission to Canadian universities.
