International Education Systems

What International Education Systems does

International Education Systems (IES), a UK-registered private limited company headquartered in Bristol (Company Number 02657335), operates the English-language branch of the family-owned Institución Internacional SEK. IES manages a global K-12-to-university network comprising 12 IES-branded schools and 14 SEK-branded schools across 17 countries, enrolling over 25,000 students from roughly 50 nationalities, plus three higher education institutions: Universidad SEK Chile, Universidad Internacional SEK Ecuador, and IUNIT Madrid.

The core offering is a bilingual (English/Spanish) international curriculum built on the proprietary "Whole Child Approach" educational model, the Cambridge curriculum, and International Baccalaureate programs, augmented by an ecosystem of international mobility programs (INTERSEK Sports, INTERSEK Cultural, Ski Week, Winter Week, Summer Programs, Green Week, Bridge Program, and Boca Prep/St. John's exchange tracks). The platform is differentiated less by technology than by its cross-campus student mobility, multi-generational brand (founded 1892 in Madrid as Colegio San Estanislao, with the Segovia family in control since 1935), and continuous K-12-to-degree pathway.

Revenue is generated primarily through recurring annual tuition at 26 schools plus fees at three higher education institutions and ancillary international program fees. Distribution is direct-to-consumer via individual school admissions offices and a centralized iesedu.com portal, supported by SEO and organic social channels. The institution is privately held by the Segovia family with no disclosed external funding rounds, and is currently led by President Mónica Segovia following a 2025 generational transition.
