School score 3/100 blends this school's own published attendance with the advantage and Year-12 attainment of its area. It is our estimate from open data — not an official rating, not ICSEA, and not a measure of teaching quality.
Area advantage (our Community Advantage Index) is our own estimate of the surrounding community's socio-educational advantage, derived from ABS SEIFA — how it's calculated. It describes the suburb, so every school in South Grafton shares it. It is a community indicator, not a school-quality score, and is not ICSEA.
