The international K-12 school sector continues to expand steadily, extending a six-year growth trend across global education markets. A new white paper from ISC Research reports a +2% year-on-year increase in 2026, bringing the total number of international schools worldwide to 15,075. Together, these schools generate US$69.3 billion in annual fee income, enrol 7.7 million students, and employ around 730,000 staff.

Asia remains the dominant region, accounting for 58% of all international schools globally. The remaining schools are spread across the Americas (15%), Europe (14%), Africa (12%), and Oceania (2%).

UAE Emerges as One of the Fastest Growing Markets

While China still has the highest number of international schools, growth in the country is beginning to slow.

In contrast, the number of schools increased by +2% in India and +7% in the UAE. ISC Research identified the UAE, Indonesia, and Kazakhstan as some of the fastest growing international school markets.

The report also noted that the UAE currently leads globally in planned K-12 international school developments, with 36 schools in the pipeline. Demand remains particularly strong, with waiting lists reported across multiple grade levels in the country.

Rise in Accredited and Bilingual Schools

The report highlights significant changes in the structure of international education worldwide.

There are now +34% more accredited international schools globally, alongside a +17% increase in schools offering bilingual education.

More than one-third of international schools now provide bilingual instruction, reflecting growing demand from local families seeking internationally focused education while maintaining national language and cultural identity.

International Schools Becoming More Integrated Locally

ISC Research says the sector is undergoing a structural shift, with growth increasingly driven by local families rather than expatriate communities.

This transition has encouraged schools to offer curricula that balance international standards with national educational priorities. According to ISC, many schools are now reflecting “national requirements, local language, and cultural context.”

The report also found that 78% of international schools now follow a hybrid model combining local educational needs with global learning outcomes. ISC says:

“International schools are no longer positioned at the margins of national education systems they are increasingly integrated within them.”

Local Strength and Global Expansion Driving Success

The report suggests that future success in the international school sector will depend on operators being able to adapt to local markets while maintaining global reach. As ISC explains, the most successful new entrants are those “who can operate locally and expand globally.”
