The US international school market in 2026
The United States is unusual among major destinations because its mainstream schools are themselves a draw, which keeps the dedicated international school market smaller and more specialised than its size would suggest. The schools that describe themselves as international cluster in the largest metros and serve three groups: diplomatic and consular families, globally mobile corporate transferees who want a qualification that travels, and families who want their children educated in French, German, Japanese or another home language. New York holds the deepest market, with Boston, Washington DC, the San Francisco Bay Area, Los Angeles, Chicago, Houston and Miami close behind. To compare the international route with the curriculum your family already knows, start with our curriculum library and the compare hub.
The defining feature of the US market is the strength of the local alternative. Many globally mobile families in the USA choose a strong public school district or a domestic private school rather than a dedicated international school, reserving the international option for cases where curriculum portability or home language schooling genuinely matters. That makes the choice in the USA more deliberate than in markets where the international school is the obvious default. Families who do want the international route are usually clear about why, which shapes the rest of the decision.
Curricula on offer
The International Baccalaureate is the most prominent full international curriculum in the USA. IB World Schools deliver the Primary Years, Middle Years and Diploma programmes, and US selective universities read the IB transcript fluently and award college credit for strong Higher Level scores. The United Nations International School and Dwight School in New York are among the long established IB names. The IB Diploma guide covers the structure and the university recognition in detail, and our IB versus Advanced Placement comparison is the key read for families weighing the IB against the standard US route.
The British curriculum is offered by a smaller set of schools serving UK and Commonwealth families and children mid way through IGCSE who need continuity. These schools deliver the English National Curriculum, Cambridge or Edexcel IGCSE and A Levels, often blended with IB approaches in the early years. Read our British curriculum guide for the detail. The French Lycee network, following the French Baccalaureate, is well represented in New York, Washington, San Francisco and Los Angeles and is explained in our French curriculum guide. German schools following the Abitur, Japanese schools following the MEXT curriculum and a handful of bilingual or multi diploma schools complete the picture. For families considering the standard US programme alongside these, the American curriculum guide sets out the AP and US High School Diploma route.
Top cities and clusters
New York is the clear leader, with around 21 recognised international schools spanning the IB, British, French, German and Japanese systems, from Manhattan campuses to larger sites on Long Island. Boston and the surrounding Cambridge area hold a strong cluster anchored by IB and French provision and serving the city's universities and biotechnology sector. Washington DC has a deep diplomatic driven market with major French, German and IB schools. The San Francisco Bay Area, Los Angeles, Chicago, Houston and Miami each hold their own clusters, typically built around an IB World School, a French Lycee and one or more national curriculum schools.
GlobalSchoolGuide does not yet publish dedicated US city hubs, so this guide describes the clusters rather than linking to city pages that do not exist. As US city guides come online they will be linked here so the country hub routes down to every city we cover. In the meantime, families can use the tools below to build a shortlist and can read parent reviews for context on what families weigh when choosing a school.

Fees overview
International schools in the USA are among the most expensive in the world, reflecting high US private school costs generally. Treat the figures below as bands rather than firm quotes and confirm current tuition with each school. Use the fee comparison tool for like for like comparison and the wider fees database for the full picture.
| Segment | Typical provision | 2026 tuition (USD) | Notes |
|---|---|---|---|
| Sector average | All international schools | ~31,000 | Across the full range of schools |
| British curriculum schools | IGCSE and A Level | ~42,000 average | Higher than the sector average |
| Established IB and full international | New York, Boston, DC | 35,000 to 60,000 | Before registration and extras |
| French and German schools | Baccalaureate, Abitur | 25,000 to 40,000 | Often subsidised for national families |
Beyond tuition, budget for registration, capital contributions, transport and trips. US schools also commonly invite annual giving, which is voluntary but a visible part of the culture. The all in cost at an established New York international school can reach the upper end of these bands once extras are included.
Admissions calendar
The US academic year runs from late August or early September to June. Admissions to the established city international schools are competitive and run on an early cycle: many schools open applications in the autumn for entry the following September, with deadlines often falling between November and January and decisions in the spring. The most sought after New York schools maintain waiting lists at the entry year groups. Families relocating mid year should contact schools directly, as places outside the main cycle depend on capacity and can open at short notice.
The application process typically includes school reports and references, an age appropriate assessment or admissions test, a child visit or interview, and a family meeting. For visa dependent families, schools are familiar with the documentation that accompanies diplomatic and work visas and can usually advise on timing. Apply as early as the cycle allows for the established schools, and keep a second choice open given how competitive the entry year groups can be.
Choosing a school
First, be clear on why you want an international school rather than the strong local alternative. If the answer is curriculum portability for a family that will move again, the IB Diploma is usually the cleanest choice. If it is home language schooling, the French, German or Japanese schools are purpose built for that. If it is continuity for a child mid way through IGCSE, a British school is the obvious fit. The reason should drive the shortlist.
Second, weigh the international school against the public and domestic private options honestly, because in the USA those are genuinely strong. For a family settling long term whose children will apply to US universities, a top public district or a domestic private school can serve as well as an international school and at lower cost. Use the relocate hub to plan the wider move and the IB versus AP comparison to test whether the international qualification adds enough to justify the premium.
Third, look at university destinations and credit. US selective universities read the IB fluently and award credit for strong Higher Level scores, while A Levels are accepted but usually want the SAT or ACT alongside. If your child is targeting US universities, ask each school where its leavers go and how it supports the US application, which is itself a substantial undertaking. The honest answer reveals how well the school bridges its curriculum to the destination your family is aiming at.
