Why Brussels Is One of Europe's Most International Cities for Families
Brussels occupies a unique position in Europe: it is simultaneously the de facto capital of the European Union, home to NATO headquarters, and a major hub for diplomatic missions, multinational corporations, and international NGOs. The result is an expat population that is unusually large relative to the city's size — and a school market shaped accordingly. International schools in Brussels have decades of experience welcoming children who arrive mid-year from other countries, speak multiple languages at home, and will likely move on again within a few years.
For parents, this means that the admissions process in Brussels is generally well-structured and accessible. Schools are accustomed to international applicants, and most have clear, predictable application timelines. That said, the city's popularity means that the most established schools can have waiting lists, particularly for certain year groups — and knowing how to navigate those lists can make a real difference.
The Brussels School Calendar and Key Admissions Windows
Most international schools in Brussels follow the Northern European academic calendar, starting in late August or early September and running through June. The primary intake window for new students is in the spring and early summer ahead of the September start — meaning families who know they will be moving to Brussels in August should begin their school search no later than February or March of that year.
Many schools also accept rolling admissions for mid-year arrivals, which is essential given the nature of diplomatic and international corporate postings. If you are arriving outside the standard intake period, contact schools directly to understand their capacity for mid-year entry in your child's year group. Some schools have structured programmes for mid-year arrivals; others handle them case by case.
If the most sought-after schools have waiting lists for your child's year group, ask specifically how the list is managed. Brussels schools typically manage waiting lists in date-of-application order, but some give priority to siblings of enrolled students or children of staff. Understanding the list mechanics helps you decide whether to wait or pursue alternative options in parallel.
BEPS International School: A Leading Choice for English-Speaking Families
BEPS International School — the Brussels English Primary School — is one of the city's most established and well-regarded options for English-speaking expat families. Founded specifically to serve the international community, BEPS has a long track record of supporting children through transitions and provides a nurturing environment that many parents find ideal for younger children making their first international school move. The school's admissions team is experienced at handling inquiries from families still in the relocation planning stage and can advise on timelines and documentation well in advance of a move.
St. John's International School: IB from Early Years to Diploma
St. John's International School offers the full International Baccalaureate continuum from the Primary Years Programme through to the IB Diploma. For families committed to the IB framework — particularly those who have followed it in previous postings — St. John's provides end-to-end continuity. Its admissions process is clearly documented and the school's experience with IB transfers from other countries makes it well equipped to assess and place incoming students accurately.
What Documents You Will Need for the Application
Brussels international schools typically require a consistent set of documents for admission. You will generally need the last two or three years of school reports, translated into English or French if they are in another language; a letter of recommendation from your child's current teacher or headteacher; proof of the child's language ability if the school teaches in a language other than the child's home language; a copy of the child's passport or identity document; and proof of immunisation. Some schools also require a brief student questionnaire or learning profile, and most conduct a student interview or assessment as part of the process.
For older students applying to secondary programmes, additional requirements may include a writing sample, subject-specific assessments, or reference letters from subject teachers. Gather documents early — particularly school report translations, which can take time to arrange — to avoid delays in the application process.
Language Support and EAL Provision
Given the multilingual nature of the Brussels international community, most schools have developed strong English as an Additional Language (EAL) programmes. However, the quality and intensity of EAL support varies considerably between schools. When visiting schools, ask specifically about the EAL withdrawal model: how many hours per week does an EAL student receive additional support, how long do students typically remain in the programme, and how is the transition back into full mainstream classes managed?
Brussels is also a city where French language acquisition can be a significant practical benefit for day-to-day life outside school. If your child is interested in learning French, check whether the school offers it as a substantive curriculum subject rather than just a token elective.
