Trade-offs
- !Premium fees — SGD ~30,280–53,500 per year (2026/27), upper tier of the Singapore market
- !For-profit ownership — owned by China Maple Leaf Educational Systems since 2020
- !Very large enrollment (~3,100) may feel less personal than smaller boutique schools
- !No published IB results — the school markets 'exceptional' outcomes but publishes no numeric average or pass rate
- !No boarding — day-school only
- !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
