About international schools in Brussels, Belgium

Catholic international schools in Brussels combine a Catholic ethos with bilingual or trilingual teaching and a mix of nationally recognised and international curricula, so families can expect both faith-based pastoral provision and an outward-looking, multilingual classroom culture. Many operate French-/English or French-/Dutch immersion sections while also offering internationally recognised pathways such as Cambridge (IGCSE/A-Level) or the International Baccalaureate alongside programmes recognised by the Wallonia-Brussels authorities. Published annual tuition at these schools typically sits in the mid-range for Brussels international education, with examples running from roughly €8,000 in early years up to around €20,000 - €21,000 for upper secondary, and additional charges for registration, exams and trips are common. Admissions follow the school year (September - June); practical steps include submitting recent school reports (often with translations), identity documents and, where required, language assessments or interviews, so families should start enquiries in late winter or early spring to allow for places or waiting lists.

FAQs for Belgium

What curricula will my child likely encounter at a Catholic international school in Brussels?
You will commonly find a blend of curricula: the Belgian (Wallonia-Brussels) programme or accredited local programmes, Cambridge international programmes (IGCSE/A-Level) and, at some schools, the International Baccalaureate Diploma. Schools may combine a national curriculum for statutory recognition with an international route for global university access, so check which final qualifications the school delivers.
What languages are used and how is language support delivered?
French, Dutch and English are the most frequent languages of instruction; many Catholic international schools run bilingual or trilingual immersion sections (for example French/English or French/Dutch) and add a third language at secondary level. Expect dedicated English-as-an-additional-language (EAL) support and staged language entry points rather than only one single language stream; schools publish their language-policy details and typical timetables.
How much should we budget for tuition and extra costs?
Published tuition at Catholic international schools in Brussels varies by age and registration type but examples show annual fees from around €8,000 in younger years up to roughly €20,000 - €21,000 for upper secondary; employer-sponsored (professional) rates may be higher. In addition to headline tuition most families pay a non-refundable registration or acceptance fee, exam fees (IGCSE/A-Level/IB), school trips, uniforms, instrument lessons and optional after-school care, so check each school’s full fees list before committing.
When should we apply and what does the admissions process usually involve?
Admissions broadly follow the September - June academic year, so parents aiming for entry the following autumn should begin enquiries and submit completed files in late winter or spring; some popular entry years have waiting lists. Typical requirements are recent school reports (with translations if not in French/Dutch/English), identity documents, a teacher reference and sometimes an assessment or interview to identify language support needs.
What ages and qualifications do Catholic international schools cover?
Most of these schools cover pre-primary through to the end of secondary (approximately ages 2 - 18), with early years and primary focusing on immersion and language foundations and secondary preparing students for recognised leaving qualifications such as Belgian certificates, Cambridge IGCSE/A-Levels or the IB Diploma. Confirm with any school whether its final-year qualification is recognised by Belgian higher education if that matters for future university entry.
