Why Hong Kong is strong for IB
Hong Kong's English Schools Foundation (ESF) consciously moved its secondary schools to IB Diploma over the early 2010s, creating one of the largest IB cohorts in any single education system globally. Alongside ESF, several premium private schools (CDNIS, GSIS, ICS, Renaissance, Discovery) run IB at high standard. The combined effect is a deep teacher pool, mature exam preparation infrastructure, and parents who understand the system.
The 2026 top 8 IB schools in Hong Kong
German Swiss International School (GSIS)
Hong Kong's most consistent IB results. Three-year average above 37 points. Strong language and humanities programmes alongside competitive STEM. Cohort skews to long-tenured expat and Hong Kong Chinese families. Strong destinations across UK, US, German-speaking Europe and Asia.

What didn't make the list
Several Hong Kong schools offer the IB Diploma at competitive levels but don't make our top 8. typically because cohort averages are below 32 points, the IB cohort is very small (under 25 students per year), or the IB authorisation is recent.
