What does ISC consider to be an international school?

For the purposes of market intelligence, analysis and data collection, ISC Research includes an international school if the school delivers a curriculum to any combination of pre-school, primary or secondary students, wholly or partly in English outside an English-speaking country.


If a school is in a country where English is one of the official languages, it offers an English-medium curriculum other than the country’s national curriculum and the school is international in its orientation.
