ISS International School, Singapore Reviews
We read Reddit, Facebook, and expat forums so you don't have to.
ISS International School Singapore is widely characterised as a small, community-led IB school rather than a large-campus operator. Recent, independent commentary points to a warm culture and close relationships, with recurring caveats about modest facilities and the realities of being a smaller, not-for-profit school.
What parents consistently praise
A February 2026 review byemphasises ISS's "kampong spirit", small classes and a through-train IB continuum, describing a village-style feel on a hilltop site. A June 2024 parent feature on HoneyKids Asia similarly highlights staff who made families feel at home quickly, with teachers seen as accessible and attentive.
“At ISS, we're like a big family. Everyone knows everyone else's name, and we look out for one another.”
Where the criticism lands
The samepiece notes that first impressions can read as dated or rundown, and that the steep, heritage-heavy site is not purpose-built. A June 2025 thread on Reddit discusses pressures linked to limited resources and lower pay in a not-for-profit setting, and claims the move to a smaller, older campus reduced its standing among Singapore's long-established schools.
“It is a nonprofit in a sea of for-profit schools.”
Admissions
Independent sources do not point to a single admissions bottleneck, but do frame ISS as a small school where fit matters. Prospective families should look closely at the campus environment and ask how language support is delivered in practice, given references to a substantial EAL population and a strong EAL programme.

Resources and staff conditions
