🇭🇰 Hong Kong · Side-by-side comparison on verifiable public data.
Reviewed by Priscilla Han
Which should you choose?
Both run British, so the difference is inspection rating, boarding, and fees rather than the curriculum itself; Kellett School has a public inspection verdict (BSO "Outstanding") while the other sits in a market with no public inspectorate, judged on accreditation instead; Harrow International School Hong Kong offers boarding while the other is day-only. The choice comes down to target curriculum, whether you need boarding, and budget — verify fees against each school's own figures.
Kellett School holds a public inspection verdict (BSO "Outstanding"), while Harrow International School Hong Kong operates in a market with no public inspectorate — the former has a verifiable official quality anchor, the latter is judged on accreditation depth. Both run the same curriculum (British), so the differences come down to pathway detail, campus culture, and specific language/boarding arrangements rather than the curriculum framework itself. One practical difference: Harrow International School Hong Kong offers boarding while the other is day-only — decisive for families who need a residential option. Verify current fees against each school's own figures (see the table below).
