Students are assigned evenly across the four Junior School houses and eight Senior School houses upon commencement at Trinity. Those students with an existing relationship to the school are typically allocated to the House of their siblings and generational family members (such as parents or grandparents) unless otherwise requested

About the House system

Di Salvitti, Senior Head of House

When a student begins in the Senior School at Trinity, their house colour is adorned as a small strip on their school tie, connecting them with the other roughly 125 students in their house community.  

The best part of overseeing the House Program is witnessing the multi-age interactions between the students, as well as seeing their individual journeys as students move through the school. Being in a house is one of the few opportunities that Trinity students have to work with younger and older peers towards a common goal – whether that be as grand as putting on a show for House Performing Arts Festival (HPAF), or as seemingly minor as winning musical chairs against other “house families” in a Tuesday Assembly. This cross-age camaraderie transcends allotted house activity time, and can be seen in high-fives as different year levels pass each other in the hallways or greet each other at the tram stop. 

Additionally, it is wonderful to see the trajectory of keen, nervous Year 7s turn into confident and passionate house leaders by Year 12. The house program gives every Trinity student a connection beyond their year level, a shared purpose and a place to be.

Each house creates a smaller, more dynamic and supportive peer network for students, and foster an immediate sense of belonging for those in younger year levels or new to Trinity. House groups meet regularly, led by their staff Head of House and student House Captain, to deepen these connections and build a greater sense of camaraderie and togetherness. 

Opportunities for students to compete for their house include swimming, athletics, music, performance and a large range of cultural activities.  

A highlight in the house activities calendar is always the House Performing Arts Festival (HPAF). Each house works together to put on an entirely student-written performance of acting, singing and dancing, which is then performed in competition with the other seven houses.

Buddy Program

The Buddy Program operates across the Junior School campus, where we see: 

  • ELC students paired with Year 4s 
  • Prep and Year 1 students paired with Year 6s 
  • Year 2 and Year 3 students paired with Year 5s 
  • Prep-Year 6 students paired with their counterparts from Ruyton Girls’ School  

Buddies provide support for new and younger students, and give older students the opportunity to step up as mentors and leaders. They also offer new and different opportunities for connection with others.  

Before commencing at Trinity, Junior School students receive a special personal letter from their buddy with some words of encouragement and excitement for the journey ahead.
