Australian International School vs Overseas Family School
🇸🇬 Singapore · Side-by-side comparison on verifiable public data.
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
