The elite independents

Pembroke School in Kensington Park has the highest ICSEA in our Adelaide set (1,182). It is a non-denominational co-ed school offering the IB Diploma alongside SACE, with a dedicated Hearing Unit and boarding for up to 125 students in Years 7 to 12. Wilderness School in Medindie (ICSEA 1,178) is a Round Square girls' school known for its distinctive Year 13 gap-year style program.

St Peter's College in Hackney is one of Australia's oldest boys' schools (founded 1847), with a strong rowing and rugby tradition, the IB Diploma and eight Nobel Laureate alumni. Westminster School in Marion (ICSEA 1,152, Year 12 tuition around $21,680 for 2026) is a co-ed Uniting Church day and boarding school on a 23-hectare campus originally opened by Prime Minister Robert Menzies.

Strong co-ed and single-sex options

Prince Alfred College in Kent Town is a Uniting Church boys' school with a deep cricket and AFL heritage, the Da Vinci Decathlon and a Round Square international program, accepting boarders from Year 5. Scotch College Adelaide in Torrens Park is a co-ed IB World School (PYP and Diploma) with a strong outdoor education focus, and Pulteney Grammar runs a city-edge campus on South Terrace plus the Kurrajong outdoor centre at Mount Compass.

For girls, Walford Anglican (ICSEA 1,173, IB PYP), Seymour College (IB World School) and St Peter's Girls' School (IB PYP and Diploma, strong STEM and performing arts) all sit in the high-$20,000s for Year 12.

Strong value: Catholic and Lutheran schools

If the elite tier is out of budget, Adelaide has excellent value options. Mercedes College in Springfield (Mercy Sisters, ICSEA 1,138) offers the IB Diploma alongside SACE for around $13,280 a year, the lowest Year 12 fee in our Adelaide set. Concordia College, a Lutheran co-ed school in Highgate, sits around $18,420 and offers boarding for regional SA and Pacific families.

How to use ICSEA and fees together

  • ICSEA is a community measure, not a quality score. A score above 1,000 means the student community is, on average, more socio-educationally advantaged. It does not directly measure teaching or results.
  • Fees buy facilities and co-curricular breadth, not guaranteed outcomes. Mercedes College posts a competitive ICSEA at roughly a third of the elite fee.
  • Decide on SACE vs IB early. If your child suits the IB Diploma, focus on Pembroke, St Peter's, Scotch, Seymour or St Peter's Girls'.
  • Factor in the extras. Uniforms, IT, camps, music tuition and boarding can add $5,000-$32,000 a year on top of headline tuition.

Boarding in Adelaide

Adelaide schools draw boarders from regional SA, the Riverland, the Eyre Peninsula and interstate. Pembroke, Walford Anglican, Wilderness, Prince Alfred, St Peter's College, Scotch College Adelaide, Westminster, Seymour and Concordia all run boarding houses. Prince Alfred accepts boarders from Year 5. Boarding fees are charged on top of tuition, so budget for the combined figure.
