Trade-offs
- !Premium fees: SGD 37,520–59,220 for 2026/27 — among the higher tiers in Singapore
- !No boarding — day school only
- !EAL/English-language support is not documented on a public primary source — verify directly
- !No public independent inspection report (BSO/ISI rating band) was locatable
- !Large size (~2,930) may not suit families seeking a small, intimate environment
- !Small scale typically means fewer specialist facilities, sports teams and CCA breadth than large campuses (ISS joined EAPISA, an association for small international schools)
- !No published total enrollment figure, limiting transparency on cohort size
- !Fees are mid-to-high (senior grades exceed SGD 50,000/year before development and protection-scheme fees), without the facilities footprint of similarly-priced larger schools
- !No independent inspectorate rating published (EduTrust is a regulatory certification, not a graded inspection)
- !Published IB results (top score 43; 94% diploma rate) are school-reported and not independently verified
