Located seven kilometres from Westlands on the outskirts of Nairobi, ISK is a coeducational day school for pre-kindergarten to Grade 12.

In the high school, students choose from an option-loaded program that includes the International Baccalaureate. This program is suited to all students who are prepared to accept its challenging academic requirements, and those earning the IB diploma are prepared for university entrance nearly everywhere in the world. The faculty of ISK represents several countries and averages 12 years of classroom experience. Every teacher has a university degree and more than half hold either Masters' or Doctors' diplomas.
