ICSEA measures the community a school serves, not the school itself. The national average is 1,000; it is built from parental occupation and education, remoteness and Indigenous enrolment.

Why community composition matters

iPlain-English notes on how to read these figures.

ICSEA is not a quality ranking. ICSEA describes the socio-educational advantage of the community a school serves. It says nothing about how well the school teaches.

Always compare like with like. Compare a school with others that have a similar ICSEA, not with the national picture alone.

The composition shift over time. The four quarters show how the school's students are spread across the national scale; a change over the years shows the intake changing.

SEIFA supplements ICSEA. SEIFA indexes describe the area around the school from Census data, while ICSEA is built from the school's own students and families.
