What is the best k-12 school in South Australia?

Pulteney Grammar School in Adelaide ranks first among K-12 schools in South Australia with a Success Index of 86.7 out of 100 and an ICSEA of 1170.

How are K-12 schools in South Australia ranked?

Each school's Success Index combines five factors from ACARA's 2025 school profile data: ICSEA (50%), share of students in the top socio-educational quarter (15%), students per teacher (15%), five-year enrolment growth (10%) and five-year ICSEA trend (10%). Each factor is a percentile against schools of the same type nationally. Schools with fewer than 80 students are excluded.

How many public schools are in the top 100 K-12 schools in South Australia?

22 of the top 100 K-12 schools in South Australia are government schools; 78 are Catholic or independent.

Do these rankings include NAPLAN or ATAR results?

Not yet. ACARA does not publish school-level NAPLAN results in bulk, and ATAR results are released by state authorities in different formats. The Success Index uses the measures ACARA publishes for every school so that all schools are compared on identical data. Where a school publishes its own results we link to its website.
