Spain has one of the largest international school markets in Europe, spread across Madrid, Barcelona, the Costa del Sol and beyond. Here's how the sector is structured, what curricula you'll actually find, and how to start narrowing down a shortlist.
A parent's guide to international schools in Spain: how the sector works, common curricula, regional variation, and how to build a realistic shortlist.
In everyday parent conversation, "international school" in Spain usually means a school that teaches mainly in a language other than Spanish (most often English), follows a curriculum with origins outside Spain (British, American, IB, French, German and others), and is aimed at least partly at expatriate and internationally mobile families alongside Spanish families who want an international education for their children.
This is a loose, functional definition rather than a formal legal category. Spain's education authorities classify schools by their formal status (state, concertado, or private/privado) and by the curriculum and inspection framework they follow, not by a single "international school" label. A school can be fully private and still primarily deliver the Spanish curriculum in Spanish; equally, some schools with international curricula also carry Spanish accreditation to allow pupils to sit the Spanish Bachillerato alongside, say, the IB Diploma. Always check exactly what a specific school offers rather than assuming from its name or marketing alone.
Spain's international school sector has grown up around the places with the largest and longest-standing expatriate and internationally mobile communities. Madrid and Barcelona, as the two largest cities, host the widest range of curricula and the largest number of schools overall. Valencia has a smaller but well-established sector. The Costa del Sol around Malaga and Marbella, the Balearic Islands around Palma de Mallorca, and areas of the Costa Blanca such as Alicante and Javea also have a notably dense concentration of international schools relative to their population, reflecting decades of residential and retirement migration from the UK, Scandinavia, Germany and elsewhere.
This geography matters for planning: a family moving to a smaller Spanish city or a rural area may find far fewer international options within a reasonable daily commute, and may need to weigh a longer journey against a local bilingual or Spanish state school instead. Always map the realistic radius around your intended home before assuming a particular curriculum will be available nearby.
British-curriculum schools are widespread across Spain, often following the English National Curriculum through to IGCSEs and A-levels, sometimes alongside the IB Diploma in the sixth form. American-curriculum schools exist mainly in Madrid, Barcelona and a handful of other cities, often culminating in a US high school diploma and, at many schools, an AP or IB option. The International Baccalaureate is offered widely across all four programmes (PYP, MYP, DP and, at fewer schools, the Career-related Programme), sometimes as a stand-alone school and sometimes as one strand within a school that also teaches a national curriculum.
French, German and other national curricula are also present, generally in the cities with the largest historic communities from those countries, through lycées and Deutsche Schulen. Some schools blend an international curriculum with the Spanish Bachillerato so that pupils can leave with qualifications recognised in both systems. Curriculum offerings, and which qualifications are actually examined at a given school, change over time, so always confirm current provision directly with the school rather than relying on older listings.
Choosing an international school depends on your child's age, curriculum preference, location and budget. Tell us what you're looking for and we'll help you identify schools worth considering.
Spain's school system has three broad categories that every family researching schools should understand before going further: state schools (público), publicly subsidised but privately run schools (concertado), and fully private schools (privado). International schools in the sense used in this guide are almost always privado, meaning they are funded through fees rather than the state subsidy that concertado schools receive. Our dedicated guide on state versus private schools in Spain goes into this distinction in more depth, since it shapes cost, admissions and curriculum in ways that are easy to misunderstand from outside the system.
Because education administration in Spain is substantially devolved to the autonomous communities (Madrid, Catalonia, Andalusia, the Valencian Community and others), some of the detail around inspection, bilingual programme labelling and even terminology varies regionally. Treat anything region-specific you read, including in this guide, as a general pattern to verify locally rather than a fixed national rule.
A small number of Spain's international schools offer boarding, generally in areas with a strong tradition of attracting families from further afield, such as parts of Andalusia. Boarding provision, age ranges accepted, and weekly versus termly boarding patterns vary considerably by school, so ask each school directly for its current boarding policy rather than assuming a particular structure.

Start from your family's non-negotiables rather than a generic "best schools" list. Curriculum continuity matters if you expect to move again, so think about which system your child's future school, university or exam board is likely to sit within. Location matters enormously in Spanish cities with significant traffic, so map realistic commute times before falling in love with a school on the far side of town. Language exposure matters too: some families want maximum immersion in Spanish or a regional co-official language such as Catalan, Basque or Galician, while others prioritise continuity in English or another language.
Once you have a shortlist of three to six schools that plausibly fit your logistics and curriculum needs, contact each one directly for a tour, current fee schedule, and details of its admissions timeline. Do not rely solely on rankings or aggregated review sites, which can be outdated or incomplete; a direct conversation with the admissions team is the most reliable source for anything specific to your child's age and needs.
Beyond the obvious questions about fees and curriculum, ask about class sizes and how they change by year group, the school's approach to supporting children who join partway through the year (common among expat families), and how much Spanish or the regional co-official language is taught and to what level. Ask, too, about the exit pathways: where do leavers typically go on to, and does the school support applications to universities in more than one country. None of this information should be treated as fact until confirmed directly by the school, since it changes from year to year and school to school.
Almost always, yes. Schools that primarily teach in English or another foreign language with a non-Spanish curriculum are typically classified as privado (private) rather than concertado. Confirm the specific school's formal status directly, since terminology and classification can vary.
Most do, though the amount of Spanish language teaching and whether it leads to a recognised Spanish qualification varies widely by school. Ask each school directly about its Spanish language provision and any regional co-official language requirements.
Many schools accept mid-year admissions, particularly in cities with high numbers of relocating families, but places depend on availability in the specific year group at the time you apply. Contact the school directly for its current position.
Madrid and Barcelona have the widest range of curricula and schools. The Costa del Sol, Balearic Islands and parts of the Costa Blanca also have a notably high concentration relative to their population.
Broadly similar in overall shape, but exact term and holiday dates can differ by school and region. See our guide to the Spanish school year and term dates for more detail.
Yes, the IB is offered at a good number of schools across the country in one or more of its programmes, though not every school offers every programme. Check with individual schools for their current IB offering.
Visa and residency requirements depend on your nationality and circumstances and are handled separately from school admissions. Check current requirements with official Spanish immigration sources or a qualified adviser rather than the school itself.
As early as possible once a move is likely. Popular schools in Madrid, Barcelona and coastal expat hubs can have limited space in certain year groups, and admissions processes sometimes take several weeks to complete.
No, fee levels vary considerably by school, city and year group. Always request the school's own current published fee schedule rather than relying on general estimates. See our school fees guide for how to compare structures.
