Best IB Schools in Barcelona
The shortlist of Barcelona IB schools with verifiable Diploma results, by tier, fee band, and Spanish-MoE homologación status.
The brief
- Col·legi Montserrat (38) and Oak House (36) post the city's strongest published 2024–25 Diploma averages. Both sit well above Spain's IB pack and the 2024 global average of 30.32. See Col·legi Montserrat and Oak House.
- Benjamin Franklin International School is Barcelona's heritage IB school: founded 1985, CIS and MSA-CESS, IB DP and MYP plus AP, 35.0 average and 98% pass rate in 2025.
- American School of Barcelona runs American Diploma alongside IB and AP from 1962 with a 35.0 average; British School of Barcelona carries BSO Outstanding and CIS and offers IB DP at the end of an English pathway.
- St. Peter's runs the full PYP–MYP–DP continuum with a 35.3 average and a top-five Spain finish; St. George does the same continuum on a younger, Forbes-listed British campus.
- Hamelin-Laie offers dual IB and Spanish Bachillerato with full homologación and a 43-point top score in 2025; Aula Escola Europea delivers a Catalan-Bachillerato + IB hybrid at EUR 5–9k.
Barcelona's IB market is small, deep, and shaped by a regulatory fact most international cities don't face: every school on Spanish soil either delivers the Spanish national curriculum with homologación from the Ministry of Education, or is recognised as a foreign-system school teaching to a non-Spanish curriculum. That line runs underneath every IB programme in the city and decides which Spanish universities a student can enter directly.
Catalan adds a second layer. Any school that takes Spanish state recognition teaches Catalan and Spanish as core subjects through to 16. English-medium teaching with Catalan and Spanish as compulsory subjects is the Barcelona default, not the exception.
The 2024 global IB Diploma average was 30.32, with a global pass rate near 80%. Barcelona's published averages run from 30 at the bottom of this list to 38 at the top.
The top tier
These three schools combine long IB track records, full external accreditation, and verifiable Diploma results in the 35-plus band.
Benjamin Franklin International School
Benjamin Franklin International School (BFIS) is Barcelona's heritage IB school. Founded 1985, CIS and MSA-CESS dual accreditation, IB MYP and DP plus AP. Around 700 students aged 3 to 18 on a single Pedralbes campus.
Published 2025 results: 35.0 average, 98% pass rate. Fees run EUR 12,950 to 21,720 (roughly USD 14,000 to 23,500). The American Diploma sits alongside the IB pathway, which keeps both options open well into Grade 11.
American School of Barcelona
American School of Barcelona (ASB) opens earlier than BFIS, charges more at the top, and offers the widest qualifications spread of any Barcelona international school. Founded 1962, American Diploma plus IB DP plus AP, MSA-CESS accredited. The campus sits in Esplugues de Llobregat, just over the western city boundary, which costs city-centre families a longer commute.
Around 970 students. Published 2025 results: 35.0 average, Top 10 Spain. Fees span EUR 9,404 to 27,062 (about USD 10,200 to 29,200), the widest band in the city.
Col·legi Montserrat
Col·legi Montserrat is Barcelona's outlier. Founded 1926 in Sarrià-Sant Gervasi, CIS-accredited, around 1,000 students from age 0 to 18. Fees are not published, which makes direct comparison hard. Results are: a 2024 IB Diploma average of 38 and *52% A or A\ at A Level**.
Montserrat runs a hybrid Spanish-national, Cambridge and IB model with full homologación. A 38 average is the top of the Spanish IB pack; the world's strongest schools post 39 to 41.
Strong mid-tier
These schools post reliable Diploma results, hold credible accreditation or recognition, and serve a slightly different family profile than the top three.
St. Peter's School Barcelona
St. Peter's runs the full PYP, MYP and DP continuum plus Cambridge Advanced. Founded 1964 in Les Corts, around 634 students aged 1 to 18, head Carme Escorcia. Published 2025 results: 35.3 average, 4th in Spain. Fees EUR 10,700 to 21,200 (about USD 11,600 to 22,900).
St. George Barcelona
St. George Barcelona is the youngest school on this list, founded 2015 in Sarrià. Around 700 students aged 2 to 18 across a hybrid British, IB and Cambridge pathway with PYP, MYP and DP authorisations. Forbes Top 100 Spain in 2025 and 2026. Fees EUR 10,730 to 20,290 (about USD 11,600 to 21,900). St. George does not publish a Diploma average.
British School of Barcelona
British School of Barcelona (BSB) is the largest school on this list, 2,000-plus students across Castelldefels and the city centre. Founded 1958, BSO Outstanding in 2023 and 2024, CIS-accredited. The pathway is English National Curriculum through IGCSE, then IB Diploma or A Level for the final two years. Published 2024 IB average: 34.0. Fees EUR 12,220 to 19,650 (about USD 13,200 to 21,200).
Oak House School
Oak House sits in Sarrià, founded 1968, around 1,100 students aged 3 to 18 across IB DP and Cambridge Advanced. Published 2025 results: 36.0 average, 97% pass rate, the highest published Diploma score among Barcelona schools with public fees. Fees EUR 10,995 to 13,409 (about USD 11,900 to 14,500), narrow and notably below the city's premium tier.
Hamelin-Laie International School
Hamelin-Laie sits on the coast at Montgat, founded 1989, around 600 students. The pathway is dual IB Diploma and Spanish Bachillerato with full homologación, alongside IPC and IMYC in the lower years. Published 2025 results: 30-point IB average (in line with the global mean), but a top student score of 43 and a Bachillerato average of 11.024/14. Fees EUR 11,186 to 15,493 (about USD 12,100 to 16,700).
Aula Escola Europea
Aula Escola Europea is in Pedralbes, founded 1968, around 1,200 students aged 1 to 18. The school runs IB Diploma alongside the Catalan Bachillerato. Published 2024 IB average: 35.32, with a PAU average of 7.97. Fees EUR 5,390 to 8,860 (about USD 5,800 to 9,600). The combination of a 35-plus IB average at sub-EUR-10k fees is the strongest results-to-price proposition in the city.
Best for full IB continuum (PYP + MYP + DP)
A continuous IB education from age 3 to 18 is different from picking up the Diploma at 16. The PYP is inquiry-led and concept-driven; the MYP runs eight subject groups across 11 to 16 with a Personal Project and service learning. Implementation quality varies between schools, but a school authorised across all three programmes has invested in IB beyond the exam years.
Barcelona schools with confirmed authorisation across all three IB programmes:
| School | Area | Fee band (EUR) | Standout |
|---|---|---|---|
| St. Peter's | Les Corts | 10,700–21,200 | 35.3 DP average, top 5 Spain |
| St. George | Sarrià | 10,730–20,290 | Forbes Top 100 Spain 2025–26 |
| Agora Barcelona | Sant Esteve Sesrovires | 3,800–10,350 | NEASC accreditation, Forbes Top 100 |
| Princess Margaret | Barcelona City | 7,700–9,700 | First Barcelona school officially MYP and PYP certified, working toward DP authorisation |
Of these, only St. Peter's and St. George publish a Diploma average. Agora and Princess Margaret are reasonable picks on price and on PYP-MYP signal, though Diploma results and pass rates are not yet in the public record for either.

The four IB programmes and the Spanish layer
The IB offers four programmes: PYP (3 to 12), MYP (11 to 16), Diploma (16 to 19), and the Career-related Programme (16 to 19). Schools authorise for one, several, or all. Quality of PYP and MYP implementation varies far more between schools than the IB brand suggests.
The Diploma is the most legible piece. Six subjects, three at Higher Level and three at Standard Level, plus the core: Theory of Knowledge, the Extended Essay, and CAS (creativity, activity, service). Graded out of 45 points. Breadth is built in; workload is high. In strong schools the Diploma is academically equivalent to A Levels.
Two Barcelona-specific points sit on top of the standard IB picture.
Homologación. Spain requires every school operating in the country to be either delivering the Spanish national curriculum recognised by the Ministry of Education, or formally recognised as a foreign-system school teaching to a non-Spanish curriculum. The dividing line decides what your child is sitting at 18: an IB Diploma plus a Spanish Bachillerato (the dual path: Hamelin-Laie, Aula Escola Europea, Agora, Col·legi Montserrat) or an IB Diploma alone with the school operating as a foreign-system institution (BFIS, ASB, BSB, Oak House, St. Peter's, St. George). The IB Diploma is accepted by Spanish universities through the UNEDasiss route, but the dual-credential path is more direct and is the model most Spanish families choose.
Catalan and Spanish as compulsory. Any Spanish-recognised school teaches Catalan and Spanish as core subjects throughout. Foreign-system schools still typically teach both Catalan and Spanish, but with less curriculum weight. Families intending to stay in Catalonia long-term often value the dual-credential, fully-trilingual schools higher than the English-medium-only options, regardless of headline IB scores.
How to choose between them
Four questions decide most of it.
Dual credential or single? A child likely to stay in Spain for university gains a more direct route from the homologación schools (Hamelin-Laie, Aula Escola Europea, Agora, Princess Margaret, Col·legi Montserrat) which deliver the Bachillerato alongside the IB. Internationally mobile families heading for the UK, US, or Northern Europe lose less by choosing a foreign-system school (BFIS, ASB, BSB, Oak House, St. Peter's, St. George).
Continuum or just the Diploma? Three years of PYP from age three is a different education from three years of a national-curriculum primary. Five schools on this list run the full PYP-MYP-DP: St. Peter's, St. George, Agora, Princess Margaret, and Col·legi Montserrat in a hybrid model. The rest pick up IB at 16.
Geography. Pedralbes, Sarrià-Sant Gervasi, Sarrià and Les Corts hold the uptown premium provision. ASB is in Esplugues, BSB straddles Castelldefels and the city, Hamelin-Laie sits on the coast at Montgat, Agora is inland at Sant Esteve Sesrovires. The school sets the commute, which sets the neighbourhood.
Results versus fees. Oak House at EUR 11–13k posting a 36 average, Aula Escola Europea at EUR 5–9k posting 35.32, and Col·legi Montserrat (fees unpublished) posting 38, together show the city's strongest IB results are not concentrated at the top fee bracket.

FAQs
Which Barcelona IB school has the highest published Diploma average? Col·legi Montserrat at 38 points (2024), followed by Oak House at 36.0 (2025), St. Peter's at 35.3 (2025), Aula Escola Europea at 35.32 (2024), and BFIS and ASB joint at 35.0 (2025). The global average for the same period was 30.32.
Do Barcelona IB schools also offer the Spanish Bachillerato? Some. Hamelin-Laie, Aula Escola Europea, Agora Barcelona, Princess Margaret and Col·legi Montserrat hold Spanish-Ministry recognition and deliver the Bachillerato alongside the IB Diploma. BFIS, ASB, BSB, Oak House, St. Peter's and St. George operate as foreign-system schools and deliver the IB Diploma alone.
Will my child have to learn Catalan? At any school with Spanish-Ministry recognition, yes, Catalan and Spanish are compulsory through to 16. At foreign-system schools both are typically taught but at lower intensity. For a family expecting to stay in Catalonia past primary, Catalan is part of the package, not an optional extra.
Can a Barcelona IB Diploma get my child into a Spanish university? Yes, through the UNEDasiss revalidation process, which converts the IB Diploma into an entry score recognised by Spanish universities. Students with both the IB Diploma and the Spanish Bachillerato enter directly without revalidation, which is one structural argument for the dual-credential path if Spanish university is on the table.
Which Barcelona IB school is best value? On published-results-versus-fees, Aula Escola Europea stands out: a 35.32 Diploma average against fees of EUR 5,390 to 8,860. Oak House is close behind at 36.0 against EUR 11,000 to 13,400. Agora Barcelona is the lowest-fee credible IB option at EUR 3,800 to 10,350, though it does not publish a Diploma average yet.
Which Barcelona IB schools hold CIS accreditation? Three: Benjamin Franklin International School (CIS + MSA-CESS), British School of Barcelona (CIS + BSO), and Col·legi Montserrat (CIS). CIS is the most portable international school accreditation and signals governance, safeguarding and learning standards have been externally inspected.
