ISF Waterloo International School
A small British track school in Rhode Saint Genese on the Flanders Wallonia border, useful if you want individual attention without the size and price of St. John's down the road.
In brief
A small British-track school in Rhode-Saint-Genese on the Flanders-Wallonia border, useful if you want individual attention without the size and price of St. John's down the road.
Around 300 students from age two-and-a-half to eighteen, IPC at primary, then Cambridge IGCSE and A Levels through secondary. Class sizes are genuinely small and teachers know the families. CIS and COBIS accreditation since 2021, which matters for portability if you move on.
Parents who stay long term tend to praise the leadership and the responsiveness of the office. The flip side of small is thin: limited subject choice at A Level, fewer sports and activities than you would get at a bigger campus, and a sixth form that is small enough to feel exposed. Families wanting a wider IB or IGCSE peer group usually look at St. John's or BSB. Families who want their child seen, and are happy to trade off scale, do well here.

Reviews
A small British-curriculum school on the Rhode-Saint-Genèse/Waterloo border, set up for families in the southern Brussels corridor who want one campus from daycare through A Level. Around 250 pupils, classes capped at 18, and a triple stamp from CIS, COBIS and the BSO inspectorate. Parent commentary that surfaces is short but warm: engaged leadership, attentive teachers, an unusually personal welcome for new arrivals. The trade-off is scale, the obvious limits of a 250-pupil school sit alongside the close-knit feel that draws families in.
Positives
- Small, personal community. Classes top out at 18 and the whole school sits at around 250 pupils across 60 nationalities. Parents describe attentive teachers, a small but active PTA, and a welcome-buddy who calls before the first day and walks new families in.
- Curriculum and accreditation. British curriculum throughout, IPC in primary, Cambridge IGCSE and A Level in secondary. Triple-accredited by CIS, COBIS and the UK BSO inspectorate, with a recent BSO judgement of Excellent. A continuous English-medium pathway from six weeks to 18 on a single site.
- Leadership and learning environment. Belinda Yates leads the school and parents talk about engaged leadership and an individualised feel to teaching. Every teacher is trained in English as an Additional Language, which matters in a school where most pupils arrive from another system.
Considerations
- Scale and breadth. At roughly 250 pupils across the full age range, year groups are small and the A Level subject list is correspondingly tight. Current offer covers biology, business, chemistry, English, history, global perspectives, maths, French and physics. Families wanting a wide secondary menu, large sports squads or sizeable peer groups will feel the difference against the bigger Brussels names.
- Fees and tariff structure. Two tariffs run side by side: a personal rate for self-paying families and a higher corporate rate for employer-sponsored placements. 2025-26 personal fees sit roughly EUR 14,000 in pre-school rising to about EUR 24,000 in A Level; corporate fees climb above EUR 32,000 at the top end. Registration is EUR 750. Lunches, shuttle and overnight trips are extra.
- Location. Sits on Chaussée de Waterloo in Rhode-Saint-Genèse, on the southern edge of the Brussels ring. Natural fit for families in Waterloo, La Hulpe, Uccle and the southern communes; a longer haul from the European-quarter and Tervuren side, though a school shuttle helps.
