School events bring learning to life and help shape our school culture. They help students build confidence, connect with others and celebrate their progress. Events also give families a chance to be involved in school life and share in their child’s achievements.
Our school event may include:
- school orientation day, open day and school tours
- sports carnivals, excursions and incursions
- Harmony Week and Book Week events
- performances, concerts or school productions
- fundraising, charity and community events
