Australian International School vs Overseas Family School
🇸🇬 Singapore · Side-by-side comparison on verifiable public data.
Reviewed by Priscilla Han
Which should you choose?
Both run IB, British, so the difference is inspection rating, boarding, and fees rather than the curriculum itself; Australian International School 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.
Neither Australian International School nor Overseas Family School sits in a market with a public inspectorate, so both are assessed on verifiable accreditation, curriculum authorisation, and published data rather than an official quality rating. One practical difference: Australian International School 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).

Trade-offs

- !The blended HSC/IB/IGCSE model, while broad, can be complex for families to navigate
- !Very large student body (~3,000) on one campus may mean less individual attention
- !Open-entry, no-exam admissions with broad EAL intake produces a wide ability and language range within classes
- !Single Pasir Ris campus — no choice of location and a longer commute for families in western/central Singapore
- !IB PYP is not offered (IPC used at primary), so families wanting the full IB continuum from kindergarten will not find it here
- !No published IB Diploma average or IGCSE result figures were publicly retrievable
