Key takeaways
Barcelona has one of the most developed international school markets in Spain. Families arriving from the US, UK, and other countries will find American schools, British schools, International Baccalaureate (IB) programs, and bilingual options spread across the city and into the surrounding Catalonia region. But "international school" covers a lot of ground – curriculum, accreditation, language policy, and cost vary significantly between schools. This guide maps what's actually available, what each type offers, and where an accredited online school fits for families who need something the traditional market doesn't provide.
- Barcelona has a wide range of international schools following American, British, and IB curricula, with fees typically ranging from €10,000 to €25,000 per year
- Many top international schools in Barcelona are located outside the city center – in Castelldefels, La Cañada, and other suburban areas – which affects logistics significantly
- Legacy Online School is a WASC-accredited private online school serving expat families in Barcelona since 2023, with full K-12, 19 AP (Advanced Placement) courses, and live daily instruction
- Admission to popular international schools in Barcelona is competitive – applying a year in advance is standard for the most sought-after options

The International School Landscape in Barcelona
Barcelona’s international school market is genuinely larger than most expat families expect. Campuses range from established institutions with sports halls and full extracurriculars to smaller learning communities where class sizes are tight and teachers know every child by name. Curriculum tracks split three ways: American (leading to a US high school diploma), British (GCSEs and A-levels), and IB.
The American School of Barcelona – ASB – is the go-to name for US-curriculum families. It’s in Esplugues de Llobregat, covers pre-school through grade 12, and has been there long enough to have alumni whose own children now attend. BSB, the British School of Barcelona, holds the equivalent position for British curriculum families, with several campuses across the area.
Aside from those two, the list gets longer fast. Hamelin-Laie International School. Kensington School. Agora Barcelona International School. The European International School of Barcelona. AESA Prep Academy of Barcelona. The Olive Tree School. St. Peter’s School Barcelona. The International American School in Barcelona for families specifically after a US-curriculum environment. Smaller schools built around trilingual education in English, Spanish and Catalan. Others with explicit experiential learning philosophies.
Which one is the right fit depends on three things: your child’s age and current academic level, how long your family expects to stay in Spain, and which university system you’re aiming at. Those three questions narrow the list fast.
American Schools in Barcelona
If the goal is a US university, the American curriculum is the most direct route. ASB runs a full US K-12 program from pre-school through grade 12 – a long-established school community in Catalonia with a track record families can verify.
One thing worth knowing before you assume all American schools in Barcelona are equivalent: accreditation varies. The diploma format is American, but the accrediting body matters. WASC and Cognia are both legitimate US accreditors. Some schools claim accreditation that isn’t easily verifiable. Check directly with the accrediting body – not just the school’s website – before committing.
AESA Prep Academy of Barcelona is newer, founded in 2020, and positions itself around college prep for grades 9 to 12. A family relocating from Singapore found it the only Barcelona high school with an open place in October – smaller enrollment means more flexibility outside standard intake windows.
British School of Barcelona
British families and families targeting UK universities gravitate toward the BSB and similar institutions. These schools follow the British national curriculum through to GCSEs and A-levels, with teaching and learning structured around the UK academic calendar. BSB has multiple centers across the Barcelona area.
The British curriculum is strong for UK university admissions. For families considering both UK and US universities, the lack of AP courses in a British instruction school is worth factoring in – AP scores carry significant weight in US admissions.
A family from London whose son was at BSB in Year 11 added Legacy AP Calculus and AP Physics C in January. He kept his A-level track at BSB and sat both AP exams in May. UK and US university applications went out with both qualifications on the transcript.
IB Programs in Barcelona
Several international schools in Barcelona offer the International Baccalaureate diploma program, including parts of the IB continuum from Primary Years through to the Diploma. The IB is recognized by over 3,500 universities worldwide and is popular among multicultural, internationally mobile families who want a qualification that travels.
“The IB aims to develop inquiring, knowledgeable and caring young people who help to create a better and more peaceful world through intercultural understanding and respect.”
— International Baccalaureate Organization, Mission Statement
IB schools in Barcelona tend to attract global citizens – children who have lived in multiple countries and whose families prioritize open-minded international education over a single national curriculum track. Schools like Agora and the European International School of Barcelona include IB programs within their broader academic offering.
Outside Barcelona City: Schools in Catalonia
Several well-regarded international schools are located outside the center of Barcelona, particularly in Castelldefels and other suburban areas. For families living in central Barcelona, the commute to these campuses – while manageable – adds daily logistics that affect quality of life.
Families who work remotely or have flexible schedules often find that the commute question is what tips them toward an online school. A child in a Legacy live group class at 9am in Barcelona has the same teacher, the same cohort, and the same AP curriculum as a peer in Madrid or Houston. No school bus. No traffic on the C-32.
“Most colleges and universities use AP as a factor in evaluating candidates for admission. Two-thirds of admissions and enrollment leadership indicate that AP courses are extremely or very helpful in evaluating candidates for admission.”

Where Legacy Online School Fits
Legacy is not a replacement for every family’s first choice. Some families want in-person schooling and should pursue the Barcelona international school market. But Legacy is worth considering seriously in several specific situations.
A family that arrived in Barcelona in March – mid-year, no school place confirmed – enrolled their daughter in Legacy’s online high school program within a week. Same WASC-accredited curriculum, same AP track via College Board, transcript continuous from her previous American school. She sat her AP exams in May at a Barcelona test center. No year lost.
For families on non-lucrative or digital nomad visas, Legacy’s part-time K-12 courses and summer school program are also available. They go alongside a Spanish or international school placement – AP preparation, English Language Learning, or specific subjects where the local school doesn’t cover the ground you need.
Virtual clubs and extracurricular activities are included in all Legacy plans. Tuition and fees start well below international school costs in Barcelona.

Top Tips from Our Expert
Maya Robinson, College Prep Advisor at Legacy Online School
- If you’re researching international schools in Barcelona and your child is in 9th or 10th grade, the AP question matters now. British instruction schools in Barcelona don’t offer AP. If your child is targeting US universities, starting AP courses no later than 10th grade gives enough time to build a competitive score record before applications.
- Mid-year arrivals in Barcelona face a real problem: most international schools don’t take new enrollees outside their standard entry points, and waiting six months for a school place costs academic momentum. Legacy enrolls year-round, within days.
- Verify accreditation independently before committing to any school. WASC accreditation is searchable at acswasc.org. Don’t take a school’s own marketing as confirmation.
- For families using Legacy’s online high school courses in Barcelona, AP exams are available at authorized test centers in the city. Your child doesn’t need to leave Spain to sit them.
- If your family expects to move again in one to three years, curriculum continuity matters more than local integration. A WASC-accredited transcript from Legacy transfers anywhere – no credit loss, no grade-level reassessment.

Legacy Online School’s K-12 programs are available to expat and internationally mobile families in Spain. The legal status of online education as a substitute for compulsory school attendance varies across Spain’s 17 Autonomous Communities and depends on individual circumstances and visa conditions. Legacy Online School does not represent that enrollment satisfies Spanish compulsory education (educación obligatoria) requirements. Families are solely responsible for verifying compliance with applicable law in their Autonomous Community and for confirming whether their visa conditions require proof of enrollment at a Spanish school. Legacy does not provide legal or immigration advice.
