ISC Research

The most comprehensive, current and objective data and intelligence on the world’s international schools.


International school data you can trust

We process close to 300,000 data points every year and spend 4,500 hours on verification. Here is a snapshot of the new data points collected in the past year alone.










Market experts for 25+ 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.

Net Promoter Score

ISC Research use the Net Promoter Score (NPS) to benchmark customer satisfaction for the ISC Outreach product and our service and support to clients. NPS is measured as a score from -100 to +100 and we are proud that our clients rate our service as ‘World Class’ with a rating of +85 and our ISC Outreach product as ‘Excellent’ with a +58 rating.












Much of our international schools data is gathered year-round from primary sources (governments, established international schools, and market experts) by a team of skilled researchers, including a team of field researchers based in key locations of the world where international education is in most demand. Our data is accessible via our live data portals.



We compile our analysis of both quantitative and qualitative international schools data into a comprehensive range of reports, including white papers and specialist reports on trending topics, global and market-specific intelligence reports. We also produce bespoke reports, designed to provide you with the answers you need, such as benchmarking.
