Academic

In 2018, Seymour restructured its Middle School curriculum, introducing two 'super subjects', GEM and STEM from Year 6. Principal, Kevin Tutt, has introduced a wellbeing framework, GIRLbeing, which is delivered via the Strength, Optimism and Justice (SOJ) program.

Service

Crescam Ministrando, I grow by serving, has been the college's motto and guiding philosophy since the college's foundation in 1922. Service Learning is embedded in the curriculum from Reception to Year 12 and the whole-school approach is centred around ‘Justice’ for people and the world in which they live.
