Trade-offs
- !Premium fees: 2026/27 tuition HK$203,900–265,700 by band (Year 7 is HK$251,300) — among Hong Kong's higher brackets
- !Capital barrier: on top of tuition, every student needs ONE of a refundable Standard Debenture (HK$800,000), a non-refundable Development Debenture (HK$350,000), an Infrastructure Debenture (HK$6,000,000, top priority), or an annual Capital Levy (HK$40,000/student)
- !Two-stream complexity: families must commit early to English vs German pathway, and the streams diverge in qualification, language and university routing
- !The English stream's switch from A-Level to IB means A-Level seekers are not served here
- !No standalone English-as-an-additional-language (EAL) programme in the English stream — English fluency is expected at entry; class sizes, student:teacher ratio and uniform policy are not published
- !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
