From our beginnings in the early 1970s to global recognition.

The ISL Schools Group began in 1972 when the International School of London was founded as a private co-educational school. It was one of the first schools to offer the IB Diploma, graduating its first Diploma students in 1978. It now offers the IB Primary and Middle Years programmes in addition to the IB Diploma and is especially well known for its world language programmes. Students receive mother tongue or foreign language literacy lessons from early childhood as part of the curriculum.


Because of the strength of its languages programme, ISL was selected by Qatar's Supreme Education Council to open a school in Doha as part of the Outstanding Schools initiative. Continuing its expansion, ISL was chosen by Shell to acquire the Surrey-situated Prins Willem Alexander School which, at the time, was the highest performing Dutch school in the world. The ISL Schools enrol 1600 students from 82 countries and teach 21 languages across their three campuses in Chiswick, West London; Woking, Surrey; and Doha, Qatar.
