Socio-Educational Advantage — ICSEA
ICSEA (Index of Community Socio-Educational Advantage) measures the socio-educational profile of this school's community — not the school itself. The national average is 1,000. It is calculated from parental occupation, parental education, geographic remoteness, and Indigenous enrolment proportion.
Community Composition
Cairnsfoot School's community composition is broadly balanced across socio-educational quarters, reflecting a relatively diverse intake compared to many Australian schools.
The chart below shows the proportion of students at Cairnsfoot School from each socio-educational advantage quarter nationally. The white reference line marks 25% — the expected value if students were distributed evenly across quarters. Deviation from 25% in any quarter indicates a skewed community intake. The school draws predominantly from the lower half.
Why Community Composition Matters
ICSEA is not a quality ranking
ICSEA measures the community a school serves — not how well the school teaches. Two schools with identical ICSEA scores can have dramatically different teaching quality, culture, and outcomes. ICSEA is context, not verdict.
Always compare like with like
Comparing NAPLAN results between schools with different ICSEA scores is comparing communities, not schools. For meaningful comparison, look at schools within 30–40 points of each other on the ICSEA scale.
The composition shift over time
A school's community composition can shift significantly as a suburb gentrifies or a catchment area changes. A school that was below average in ICSEA a decade ago may now be serving a very different community — and vice versa.
SEIFA supplements ICSEA
SEIFA IRSD measures the geographic area around the school (from Census data). It provides a complementary view — especially useful for understanding schools in gentrifying or rapidly changing neighbourhoods where ICSEA may lag behind the on-the-ground reality.
