Frequently asked questions
What is the best school in Adelaide?

St Andrew's School in Walkerville is the highest-ranked primary school (92.3/100). Rankings summarise community advantage and momentum, so always visit a shortlist of schools before deciding.
How many schools are in Adelaide?
450 schools appear in ACARA's 2025 data for Adelaide, of which 286 are government schools.
How are schools in Adelaide ranked?
Each school receives a Success Index from five ACARA measures (ICSEA, top socio-educational quarter, students per teacher, enrolment growth relative to its council area, and ICSEA trend), as percentiles within its school type nationally. Special schools and schools with fewer than 80 students are not ranked. See the methodology page for weights and limitations.
Which suburbs does the Adelaide ranking cover?
Adelaide is defined by Australian Bureau of Statistics SA4 regions, so it covers the greater metropolitan area rather than the city council alone. Every school page links to its suburb and council pages for finer comparisons.
