Peer group = same state, sector, and education level. ICSEA describes socio-educational advantage of the school community, not school quality. Indigenous and LBOTE shares are context only (shown in the detail comparisons below, not as ranking tiles). Each metric shows this school once, then peer-group averages on the same scale.
