🇸🇬 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 Nexus International 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
- !High fees: secondary tuition reaches SGD 53,518/year (2026), among the more expensive bands in Singapore
- !For-profit ownership under Cognita
- !Large size (~2,300 students) may not suit families seeking a small setting
- !No independent regulatory inspection report is publicly available (external references are editorial, e.g. Good Schools Guide)
- !The blended HSC/IB/IGCSE model, while broad, can be complex for families to navigate
- !For-profit ownership under Taylor's Schools Group
- !High fees typical of Singapore IB schools — annual tuition from ~SGD 33,600 plus non-refundable initial fees; full per-year schedule not publicly extractable
- !Enrollment size not publicly disclosed
