National and international: what we mean
By national curriculum we mean the curriculum delivered by the host country's state or independent schools to its domestic population. In Switzerland this is the cantonal Volksschule and Gymnasium track. In Singapore it is the Ministry of Education school system. In the Netherlands it is the openbaar and bijzonder schools delivering the Dutch national programme. In Finland and Japan, the national system is famously high performing. The instruction is in the local language; the curriculum is shaped by national priorities; the school sits inside the host country's wider social system.
By international curriculum we mean one of the imported English-language curricula delivered by paid-for international schools: most commonly the IB programme, the English national curriculum delivered abroad (often as IGCSE and A Levels), the American AP and US-style high school transcript, or one of the smaller frameworks (French, German, Cambridge International). Instruction is normally in English. The curriculum is portable. The school sits inside a separate expat-facing ecosystem with its own social patterns and its own fee economy.
For deeper context on each path, see our IB curriculum guide and our international school vs local school article.
Side by side comparison
| National curriculum (host country) | International curriculum | |
|---|---|---|
| Language of instruction | Host country language, sometimes with bilingual streams | English, sometimes French, Spanish or German |
| Cost per year | Free at state schools; up to USD 15,000 at private national schools | USD 12,000 to USD 50,000 in major expat hubs |
| Integration into host country | High; child is in the local social system | Lower; expat-facing peer group |
| University access at home | Direct via host country system | Direct in English-speaking universities; depends elsewhere |
| University access elsewhere | Depends on conversion of host country qualification | Direct in English-speaking universities and most globally |
| Mobility if you move | Difficult; host country qualification may not travel | Strong continuity within international school networks |
| Academic outcome quality | Very high in Finland, Switzerland, Singapore, Japan, Netherlands; mixed elsewhere | Variable; depends on the individual school |
| Settling-in difficulty | High if child has no host language | Low; English-language environment, expat peer group |
| Best for | Families staying 5+ years with willingness to integrate | Mobile families and those staying 2 to 4 years |
The cost dimension
The simplest argument for national schools, where they perform well, is the cost. State schools in Finland, Germany, Switzerland, the Netherlands, Norway, Japan and Singapore are free at the point of use to residents. Private national schools in those countries (where they exist) run at fees a fraction of what international schools charge. A family relocating to Geneva, for instance, faces a choice between the cantonal Ecole publique (free) and an international school running at CHF 35,000 to CHF 50,000 a year. Multiplied across two or three children, the difference funds a holiday house. Multiplied across a five-year posting, it funds a degree.
The international school market exists in part because most employers do not pay for it directly outside of the most senior expat packages. Families who self-fund international school in cities where the local system is excellent are paying a meaningful premium for English-medium instruction, an expat peer group, and curriculum portability. Whether that premium is worth it depends on factors we set out below. For a detailed breakdown by city, see our fees database.

Academic outcomes by country
The case for the local school is strongest in countries with consistently high-performing national systems. Finland's compulsory education system, despite the post-PISA softening of its reputation, still produces strong outcomes with substantially less testing and homework than most international school models. Switzerland's cantonal Gymnasium system is academically rigorous and feeds the ETH and EPFL pipelines directly. Singapore's MOE schools sit near the top of every international comparison; the academic stretch is real and the resources well allocated. The Netherlands' tweetalig (bilingual) gymnasium tracks deliver Dutch and English literacy at levels few international schools match. Japan's public schools produce extraordinarily high academic baselines and strong character development.
The case is weakest in countries where the national system is underfunded, overcrowded, or politically unstable. In many Gulf states, in much of Southeast Asia, in much of Latin America, and in significant parts of sub-Saharan Africa, the national school system is not realistically open to expat children at high quality and the international school market is the default. In those countries the question is not national versus international; it is which international school. See our Dubai city guide or our Singapore city guide for the comparison by city.
Language, identity and integration
The deepest argument for the national school is integration. A child at the local school is in the local social system. They make local friends, they learn the host language to fluency, they understand the cultural register of the country you have moved to. A child at an international school in the same city is in a parallel expat society: international peer group, English-medium social life, often a high turnover of friends because expat families come and go. The two trajectories produce very different children at 18.
For a family staying in the host country for one to three years, the integration argument is weaker because the child will leave before the integration matures. For a family staying five years or more, the integration argument grows stronger every year. There is an inflection point around three years where the cost-benefit shifts. Below three years the international school's portability dominates. Above five years the local school's integration value compounds.
Linguistic outcomes also differ. A child who attends national school in the Netherlands for three years emerges with functional Dutch. A child who attends an international school in Amsterdam for the same period emerges with negligible Dutch unless the family makes deliberate effort outside school. For families who plan to stay in a country, settle there permanently, or want their child genuinely bilingual, the national school produces the linguistic outcome that the international school usually does not.
When mobility tips the balance
Mobility tips the balance back to international schools. A child mid-way through the Swiss Maturite cannot meaningfully be transferred to a Singaporean MOE school. A child mid-way through a Japanese public school cannot easily transition to a German Gymnasium. National qualifications do not travel; international qualifications do. If your family's next five years involve more than one move, the cost-benefit of the international school strengthens substantially. The mobility insurance is a real value, even if it is hard to quantify in advance. For more on this calculation, see our British vs American curriculum guide and our IB vs A-Levels comparison.
Which to pick if
If you are moving to Finland, Singapore, Switzerland, the Netherlands, Norway or Japan and staying five plus years: seriously consider the national school. The academic and integration outcomes often exceed what the international market offers and you save a six-figure sum over the posting.
If you are moving to a country whose national system is strong but you will leave in under two years: international school. The language acquisition window will not mature; the disruption of changing systems mid-secondary will outweigh the integration value.
If you have young children (preschool, lower primary) and are likely to stay: the case for national school is strongest at this age. Children acquire the host language fluently in 12 to 18 months at this stage of development.
If your child is mid-secondary at the time of the move: international school in almost every case. The cost of moving curriculum at age 14+ is high in any system.
If you have one child suited to the national environment and one not: split them only if you have to. School split between national and international fractures family social life and adds a daily logistical load that few families maintain comfortably for more than two years.
If the local national school is good and you can speak the language to support it at home: national school, almost always.
If the local national system is weak or oversubscribed for expats: international school is the only sensible answer regardless of length of stay.
Common questions from relocating families
Is it true that local schools are higher-performing than international ones in countries like Finland? Often yes, on the standard international comparisons. Finland's compulsory school system continues to outperform many of the international schools serving expat families in Helsinki, and at a fraction of the cost. The catch is the language: the child needs Finnish to function, and that is a 12 to 18 month investment at primary age.
What about the social isolation of being the only foreign child? A real consideration. In countries with large expat populations clustered in particular districts (Brussels, Frankfurt, Singapore), it is often possible to find a local school with several other internationally mobile families already attending. In smaller postings the social load on the child is higher, and this can outweigh the academic advantage.
If we go local for primary and switch to international for secondary, does that work? Yes, but with caveats. The switch is easier at the end of Year 6 than mid-secondary. Test the academic continuity carefully: a child coming out of Dutch primary into an English-medium IGCSE programme needs strong English literacy support for the first year. Families who plan this transition in advance usually navigate it well.
What if our employer offers an education allowance only for international schools? Worth asking whether the allowance can be redirected to private supplementary tutoring or a private national school. Many policies allow flexibility. Some employers also fund language tuition for children entering local schools, which materially improves the experience.
