Trade-offs
- !Premium tuition (~HK$246K–373K) plus a non-refundable Annual Capital Levy (HK$30,200/yr)
- !Legacy debenture/nomination-rights system shapes admissions priority and can disadvantage families without one
- !Highly selective with bilingual-readiness assessment — not an open-access school
- !Demanding dual-language model is challenging for children without a Mandarin foundation or strong language aptitude
- !IB primary years use a proprietary curriculum (PYP not publicly confirmed), so 'full IB continuum' is unverified
- !Very high tuition relative to most HK international schools
- !Mandatory non-refundable HK$40,000 annual capital levy on new offers
- !Multi-million-HKD debenture system that favours high-wealth and corporate families for admission priority
- !A-Level only — no IB option
- !Public enrolment figures conflict (1,382 vs 1,470); split-campus logistics for some families
