St Peter’s College students achieved a median Australian Tertiary Admission Rank (ATAR) of 91.23 – the Hackney school’s highest marks in five years.
This compares to a median ATAR of 83.15 at PAC, which has conceded its rivals have “done better than us this year”.
Both schools are still awaiting results of students who undertook the International Baccalaureate diploma, an alternative to the SACE, which may affect the final median ATARs. Those results are due next month.
Saints and Princes, in Kent Town, share a 150-year-old sporting tradition of “intercol” clashes.
Parents of both schools are charged more than $27,500 for the privilege of having their sons graduate Year 12.
PAC principal Bradley Fenner said the IB results, due in January, would lift the average ATAR but not by enough to outrank St Peters.
“We have a great rivalry and Saints have done better than us this year – all credit to them, well done,” he said.
“We are going to try and work harder next year.”
Mr Fenner said his school recorded outstanding individual results that were not just measured by 90-plus scores “but also by students who achieved their best and some better than they had anticipated”.
Mr Fenner said ATAR was an important indicator of student and school performance, but good schools also focused on developing the all-round student.
“We have started to review how we have gone and will drill down into different subjects and forms of assessment to see how we can improve,” he said.
Mr Fenner has previously railed against the SACE unfairly favouring girls over boys.
Adelaide’s group of high-fee girls schools all achieved medians above 90.
Wilderness led the pack with 95.5, St Peter’s Girls 93.55, Walford Anglican 92.9 and Seymour College 92.2.
A St Peter’s College spokeswoman said: “We are delighted with the performance of our class of 2021 cohort across academia and co-curricular activities and their contributions to the wider community.”
The most recent publicly available NAPLAN results, from 2019, also show Saints outperforming PAC.

In 20 NAPLAN categories, Saints were ahead in 17, including all tests for years 5 and 7 students, the federal MySchool site shows.
And its comparison of results with students of similar background from around the country shows Saints performing “above” expectations in seven categories across the year levels, “well above” in two and “below” in two.
PAC performed “below” expectations in nine categories.
