OUR EXPERTISE
Market experts for 30+ years
ISC Research is the leading provider of English-medium K-12 international school data, trends and intelligence. We have been collecting market intelligence and data on international schools throughout the world since 1994.
We identify international schools using these criteria:
- a privately operated school that has chosen to deliver a curriculum wholly or partly in English to some or all of its students between 3 and 18, in a country where English is not an official language; or
- a privately operated school that delivers a curriculum other than the host country’s national curriculum wholly or partly in English to some or all of students between 3 and 18, in a country where English is an official language.
