Redlands vs St Andrew's Cathedral School
🇦🇺 Sydney · Side-by-side comparison on verifiable public data.
Neither Redlands nor St Andrew's Cathedral 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. Both run the same curriculum (IB, National), so the differences come down to pathway detail, campus culture, and specific language/boarding arrangements rather than the curriculum framework itself. Both are day schools with fees in the same market band — see the table below for the figures, and verify against each school's own published fees.

Trade-offs
- !Day school only — no boarding, so families relocating without a resident parent cannot easily place a child here
- !High fees (≈AUD 47,100/yr senior years) plus extras; the IB pathway carries a further AUD 2,950/yr surcharge
- !Total enrolment is not published on the school site, limiting transparency on school size
- !Publishes HSC and IB results combined and discloses no standalone IB Diploma average points score
- !IB is confined to the Diploma (Years 11–12) — no PYP or MYP, so the IB experience doesn't run through the junior/middle years
- !No boarding — non-Sydney or overseas families must arrange their own accommodation
- !Total enrolment and class-size data are not publicly published, reducing independent transparency
- !Vertical CBD campus means limited on-site green/playing-field space versus suburban peers
- !IB Diploma carries an extra fee surcharge on top of already-high city tuition; overseas fees plus a AUD 10,000 bond are steep
- !No early-years/preschool and no PYP — entry starts at Kindergarten, so no IB continuum for younger children
