Why international school is the default (and when that is wrong)
For most expat families on company packages, international school is the default for three reasons. Curriculum continuity if you move again. English-language instruction. Employer fee support that makes the decision feel free. These reasons are real and often correct. They are not universal.
The families for whom local school is often a better choice are those who plan to stay in the host country for the medium to long term, those whose children are young enough to acquire the local language without difficulty, and those who are paying fees from after-tax income rather than through employer schooling allowances. Those families pay an enormous, often invisible, premium for defaulting to international.
Cost: the real numbers
This is the variable that should be on the table from day one, because the numbers are large. A Tier 1 international school in Singapore, Hong Kong, Geneva or Tokyo runs USD 35,000 to USD 50,000 per child per year all-in. Over 10 years for two children, that is USD 700,000 to USD 1,000,000 of after-tax income, or roughly USD 1.4 million to USD 2 million of pre-tax salary.
A local private school in the same cities runs USD 8,000 to USD 18,000 per child per year. A local state-funded school is typically free or nominal. The cost differential over a decade is enough to fund university for both children with money left over. Families who have employer support sometimes do not feel this; families paying themselves do.
| City | Top international (annual, per child) | Top local private (annual) | Local state-funded |
|---|---|---|---|
| Singapore | SGD 40K to 55K | SGD 12K to 22K | Free for citizens; SGD 13K+ for foreigners |
| Geneva | CHF 32K to 45K | CHF 18K to 28K | Free for residents |
| Amsterdam | EUR 20K to 32K | EUR 6K to 10K (subsidised private) | Free for residents |
| Tokyo | JPY 2.5M to 3.5M | JPY 800K to 1.5M | Free for residents |
| Madrid | EUR 14K to 25K | EUR 4K to 9K (concertado) | Free for residents |
The fees gap exceeds USD 200,000 per child over 10 years in most cities. For families with two or three children, this is decisive in the financial planning. See our fees explorer for city-by-city detail and our piece on hidden fees at international schools for the all-in picture.
Take the 5-minute school decision quiz
Our school finder quiz takes five minutes and produces a personalised shortlist across international, local and bilingual options based on your family's mobility, languages, fees budget and university intent.

Curriculum portability and high-mobility families
This is the single strongest argument for international over local. If your family moves every two to four years, the IB and the British curriculum port across countries with minimal disruption. A child halfway through the IB Diploma in Hong Kong can finish it in Munich or in Mexico City. A child in Year 9 of a Japanese local school cannot transplant their year of study to a Spanish local school without significant friction and grade-level loss.
The threshold matters. Families who move once during the school years can usually navigate either system. Families who move every three years pay a substantial integration tax for local schooling. The break-even point varies by curriculum: the French baccalauréat and the IB are the most portable; Singapore and Japanese local curricula are the least. See our curriculum guides for the full picture.
Integration, language and social belonging
The strongest argument for local schooling is integration. Children who attend local schools become fluent in the host language, develop friendships with local children, and acquire the cultural literacy that international school families often never gain. A child who has spent four years in a Dutch local school will speak Dutch as a native; a child who has spent four years in an Amsterdam international school will not.
The catch is that integration depends on the country, the age of arrival and the child. Local schooling tends to work well for children who arrive at primary age (5 to 9), in countries with social cohesion welcoming to expat children (Netherlands, Switzerland, Singapore, Japan up to about Y6). It tends to work less well for teenagers arriving at Year 10 or 11, when local peer groups have crystallised and academic content has accelerated.
Parents underestimate how much social belonging matters. Children in international schools often live in a bubble of similarly-mobile families, which is both a feature (built-in community of peers in the same boat) and a constraint (limited contact with the actual host country). Local schooling forces engagement.
Academic quality: where local beats international
The romantic view is that international schools are uniformly excellent and local schools are uneven. The data does not support this. The reality is that some local school systems consistently outperform most international schools, while others underperform.
Local schools that often outperform international peers include top Finnish comprehensive schools, top Dutch VWO schools, top Singapore independent schools, top Swiss canton gymnasiums, and top Japanese kokuritsu and shiritsu schools. PISA outcomes and university destination data from these systems comfortably exceed those of average international schools. Parents who default to international in these markets often pay a premium for inferior academic outcomes.
Local schools that underperform international peers include most US public schools outside affluent districts, most UK state schools outside selective grammar areas, and most state schools in the Gulf, Africa and parts of South East Asia. In these markets, the international school is genuinely the academically superior option, and the fees reflect that.
University outcomes and recognition
Universities globally accept a wider range of qualifications than most expat parents assume. The French bac, German Abitur, Dutch VWO, Swiss Matura, Singapore A-levels and IB Diploma are all recognised at top universities in the UK, US, Canada, Australia and across Europe. Less recognised are local diplomas from systems where international universities have less experience: Chinese gaokao for non-Chinese universities, certain Latin American local diplomas, and Eastern European diplomas in some cases.
The friction is usually not refusal but additional documentation: translated transcripts, sometimes a standardised test (SAT or ACT for the US), occasionally a foundation year. The strongest students from any credible local system place well at top international universities. See our analysis on IB vs AP university outcomes for the comparison data.
The hybrid option: bilingual and partner schools
Many expat families settle on a hybrid: a bilingual school, a local school with international section, or a state-funded international stream. These often combine the cost advantage of local schooling with the integration benefits, while providing an internationally-recognised exit qualification.
Strong examples include the French lycées internationaux (state-funded, bilingual sections in English, German, Spanish, Italian, Chinese), the Spanish concertado bilingual schools, the Dutch tweetalig VWO schools (state-funded English bilingual), and the Singapore SAP schools. Fees range from free to EUR 3,000 to EUR 10,000 per year, far below international school equivalents. For high-quality families this is often the best decision.
A decision framework for your family
The honest answer to international versus local depends on five inputs. How long do you expect to stay? If under three years, default international. If five years or more, seriously consider local. How mobile do you expect to be afterwards? If one more move is likely, the IB or British curriculum locks in continuity. How young are your children? Younger children acquire language and integrate faster; older children do not. How developed is the local school system? In Finland, Singapore, the Netherlands or Switzerland, local is often equal or better. In some Gulf or African markets, it is not. And how do you actually feel about your children speaking the local language and forming local friendships? For some families this is a strong preference; for others it is a nice-to-have.
Run those five questions before you assume international is the answer. For families relocating to specific cities, see our city schools guides for the local versus international balance in each market. For the broader framework see how to choose an international school.
The decision is rarely final. Families who try local for primary and switch to international for secondary are common, particularly in the Netherlands, Switzerland and Singapore. The reverse is rarer because local-system entry points narrow with age. If you intend to keep the option open, start with the more demanding language environment while the child is young, and switch to international later if needed. The reverse pathway is much harder to engineer once a teenager has built a peer group at an English-medium international school.
Frequently asked questions
Is a local school cheaper than an international school?
Almost always, yes. State-funded local schools are typically free in the host country. Private local schools are often 30 to 60 percent cheaper than equivalent international schools. The savings can be enormous over a decade.
Will my child fall behind academically at a local school?
Not necessarily. Top local schools in Finland, Singapore, Japan, the Netherlands and Switzerland deliver outcomes comparable to or better than most international schools. The risk is uneven and depends on the country and the specific school.
Will a local-school qualification be accepted at international universities?
Yes, but with friction. Local diplomas from credible systems are widely accepted at top universities globally. Some local diplomas from less recognised systems require additional documentation or a standardised test.
What is the right choice if we move every three years?
International schools win for high-frequency movers. The IB and British curricula port across borders with minimal disruption. A child in a local Japanese school who moves to Spain after three years faces a much harder transition.
What if my child arrives without speaking the local language?
Most local school systems work best when children join under age 9. Above that age, language acquisition is harder, and many families bridge with a year of intensive language tuition or a bilingual school as a stepping stone.
