Best International Schools in Brussels 2026

Brussels has one of the most developed international school ecosystems in Europe. The EU capital’s unique combination of multinational institutions, diplomatic missions, and international business creates sustained demand for top-quality international education. The result: a city that punches well above its size in terms of international school quality.

1. International School of Brussels (ISB)

Curriculum: IB (full continuum) | Location: Waterloo (16km south of central Brussels) | Fees: ~€28,000–€38,000/year

ISB is the undisputed flagship of international education in Brussels. The full IB continuum from PYP through to the Diploma Programme, exceptional university placements, and a community of 50+ nationalities make it the first choice for families prioritising IB excellence and global connections.

ISB’s alumni network includes graduates who went on to lead EU institutions, major NGOs, and global corporations — a reflection of the extraordinary peer group that grows up at this school.

2. British School of Brussels (BSB)

Curriculum: British (IGCSE/A-Level) | Location: Tervuren (east of Brussels) | Fees: ~€22,000–€33,000/year

BSB is Brussels’ premier British curriculum school, with a strong reputation for IGCSE and A-Level results and UK university placement. For British and Commonwealth families, or those targeting Russell Group universities, BSB is the natural choice.

3. Brussels American School (BAS)

Curriculum: American (AP) | Location: Sterrebeek | Fees: ~€20,000–€30,000/year

4. St John’s International School

Curriculum: IB (full continuum) | Location: Waterloo | Fees: ~€18,000–€28,000/year

St John’s offers IB in a smaller, community-focused environment. For families seeking genuine IB education at somewhat lower fees than ISB, St John’s is an excellent alternative. The school has a warm, inclusive reputation.

5. BEPS International School

Curriculum: British/IB | Location: Central Brussels | Fees: ~€16,000–€24,000/year

BEPS is one of Brussels’ most respected smaller international schools. Its central Brussels location makes it particularly convenient for families living in the city rather than the suburbs. Strong British curriculum foundation with IB options.

6. Antwerp International School

Curriculum: IB | Location: Antwerp | Fees: ~€14,000–€22,000/year

For families based in Antwerp (Belgium’s second city, also home to major multinational corporate offices), AIS offers full IB at fees below Brussels’ premium schools.

How to Choose

IB and global university placement → ISB (or St John’s for smaller community)

British curriculum, UK university focus → BSB

American curriculum, US university focus → BAS

Smaller community feel → St John’s, BEPS

EU institution family → Consider European Schools first (near-zero fees for eligible families; high quality)

---

Apply Early

Brussels is not a city where you can leave school applications until a month before arrival. ISB, BSB, and the European Schools all have significant waitlists. Start the process 12–18 months ahead of your expected arrival date.
