Great Southern Grammar School

No school score is shown for this school. No school-level attendance or destination data is published for it, so the only signals available describe Lower Kalgan as an area — they are identical for every school in the suburb. Showing an area figure as a school rating would imply a judgement the data cannot support. How we rank schools ▸

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 Lower Kalgan shares it. It is a community indicator, not a school-quality score, and is not ICSEA.
