History and Context
International schools grew out of the diplomatic environment of the first half of the 20th century. The oldest is considered to be the International School of Geneva (Ecolint), founded in 1924 by staff of the League of Nations and the International Labour Organization for their children: the first intake consisted of just eight students. The idea was simple—to give children of families constantly moving between countries a unified curriculum and common language of instruction, so that relocation would not mean starting education from scratch.
From there also grew the most well-known program today. In the mid-1960s, Ecolint teachers created the International Schools Examinations Syndicate, which by 1968 had evolved into the International Baccalaureate—an examination and diploma recognized by universities regardless of country. Post-war globalization, the growth in the number of corporate expats and diplomatic missions made such schools a mass phenomenon, and by the end of the century international education had formed into a separate industry.
Concept
For families with children, the choice of relocation country often hinges on schooling even more than on tax rates: a convenient jurisdiction without a suitable international school quickly loses its appeal. Three main educational systems are available—International Baccalaureate (IB), British, and American—and the choice between them determines the language of instruction, workload, and further path to university. Therefore, it makes sense to select a school simultaneously with the jurisdiction, even before relocation: first check whether the country has the needed program and available places, and only then finalize the route.
Three Systems
International Baccalaureate is a globally recognized program with PYP, MYP, and Diploma Programme stages; according to the organization itself, IB is present in more than 160 countries and covers around six thousand schools, and the Diploma is highly valued by universities worldwide. The British system leads students through IGCSE to A-levels with early specialization in upper grades and a natural pathway to universities in the United Kingdom and the Commonwealth. The American system is built around the High School Diploma, GPA grade point average, and Advanced Placement courses and is oriented primarily toward admission to US universities.
How Much It Costs
The price range is very wide and depends on the country and level of the school: from approximately $3,000 per year in Southeast Asia to $40,000–$65,000 and higher in premium schools in the US and Europe. Schools with the IB program typically cost 15–25% more than comparable ones, and tuition is supplemented by entrance and registration fees and examination fees—for example, around $800–$1,200 for IB Diploma exams. The education budget should be planned together with housing and insurance expenses.
How to Choose in Practice
Besides the educational system, look at the school's accreditation (IB, Council of International Schools, COBIS), language of instruction, availability of places and possibility of mid-year admission, length of the waiting list, location, and graduate reputation. The target university is also important: for British universities A-levels make more sense, for American ones—Diploma with AP, while IB remains a universal option. The presence of strong international schools itself becomes an argument in favor of specific destinations—UAE, Singapore, Switzerland, Spain.
School Determines Relocation Geography
In practice, strong international schools themselves attract families to specific locations. Dubai is an extreme example: under KHDA supervision, over 220 private schools operate there with 17 curricula for nearly 390 thousand students from 185 countries, so a foreigner has a choice of dozens of IB and British system options within one city. Singapore, Switzerland, Spain, Portugal, and Cyprus attract relocators by the same logic: first a school with available places is found, and visa and tax status are selected accordingly.
A separate story is mid-year relocation and serial moves. Families that change countries every few years stick to one system, most often IB, so the child does not have to relearn a new grading and examination logic. Therefore, when planning, they look not only at a specific school, but also at whether its program exists in the next likely jurisdictions.
Regulation: Who Admits Whom
International schools have two levels of regulation. The first is voluntary accreditation, which plays the role of a unified quality mark: International Baccalaureate authorizes schools for its programs, while the Council of International Schools (CIS), Council of British International Schools (COBIS), and American agencies like WASC and NEASC confirm management and teaching standards. For parents, accreditation is a verifiable signal that the school's diploma will be understood by university admissions committees.
The second level is the rules of the host country about who can study under a foreign program at all, and here there is much that is counterintuitive. In China, since September 2021, after the Regulations for the Implementation of the Private Education Promotion Law came into force, at the compulsory education level (grades 1-9, approximately ages 6-15), private schools are prohibited from using foreign textbooks and teaching outside the national curriculum; foreign capital cannot own such schools, and their board of directors must consist only of PRC citizens. Full-fledged education under IB or the British system at these levels remains accessible primarily to children with foreign passports.
Singapore acts more softly, but in the same direction: for a citizen of the country to enroll in a Foreign System School, a waiver from the Ministry of Education under the Compulsory Education Act is required, and it is issued at the ministry's discretion, with the application submitted by the school itself, not the parents. For foreigners there are no such restrictions—international schools there are designed precisely for expats. The UAE occupies the opposite pole: foreign programs are open to everyone, and the majority of Dubai schoolchildren study in the private sector.
Evolution and Trends
Over recent decades, the segment has evolved into a full-fledged market. According to ISC Research, by early 2025 there were around 15 thousand English-language international schools worldwide with approximately 7.4 million students, and total tuition fees approached $67 billion—almost a quarter more than five years earlier. Most such schools are in Asia: the center of gravity of international education has long shifted from Europe to the Persian Gulf and East Asia.
The student composition has also changed. A hundred years ago these were children of diplomats and expats, and today a significant share of places is occupied by local affluent families who need English-language education and a foreign university—where the law permits. In parallel, demand is growing for bilingual programs and hybrid online formats, and the wave of relocation from Russia after 2022 added interest in schools in the UAE, Turkey, Central Asia, and Cyprus. For families, this means that school choice becomes part of broader planning—along with residency, taxes, family office, and succession structure.
