VCE results (2025)
Published by the Victorian Curriculum and Assessment Authority. Study scores range from 0 to 50 with a state mean of 30; a score of 40 or above is in roughly the top 9% statewide.
Chaffey Secondary College does not yet offer Year 12, so these figures come from a small number of accelerated students sitting VCE studies early and are not comparable with full Year 12 cohorts.
Results reflect the students who sat the VCE in 2025 and are not adjusted for intake. Schools with fewer than four students in a measure are suppressed by VCAA. See top VCE schools in Victoria.Success Index breakdown
