Trinity Grammar School is an independent, Anglican, co-educational (early learning) and boys-only (Years 3-12) school located across multiple campuses in Sydney’s inner west. The school was founded in 1913 by George Chambers in Dulwich Hill — originally as a small private school — and has grown into one of Sydney’s most significant independent Anglican boys’ schools.
The school’s motto, “Detur Gloria Soli Deo” — Latin for “Let Glory be Given to God Alone” — reflects the Christian values at the heart of the school’s mission. Trinity Grammar is a founding member of the International Boys’ School Coalition, connecting it with leading boys’ schools across the globe, and maintains a strong focus on developing what it describes as “men of character.”

Multi-Campus Structure

Anglican Identity and Unique Term Names
A distinctive and historic feature of Trinity Grammar School is its use of traditional Anglican term names — derived from the Christian liturgical calendar — rather than the standard numbered terms used by most Australian schools:
- Lent Term (Term 1) — named after the Christian season of Lent
- Whitsun Term (Term 2) — named after Whitsunday (Pentecost)
- Trinity Term (Term 3) — named after Trinity Sunday
- Michaelmas Term (Term 4) — named after the Feast of St Michael
This naming tradition is shared with historic Anglican and English independent schools globally, connecting Trinity Grammar to the broader Anglican educational heritage. Each year concludes with Speech Day, a formal end-of-year celebration for the school community.
School Leadership and Community
The school places strong emphasis on pastoral care across its House Structure, Chaplaincy programme, and TESS Support Services (including counselling, psychological services, and a Health Care Centre). An English as an Additional Language (EAL) programme supports students from non-English speaking backgrounds, reflecting the diverse Inner West Sydney community.
Trinity Grammar is a founding member of the International Boys’ School Coalition and maintains international exchange partnerships. The Old Trinitarian Union — the active alumni association — supports current students through scholarships, mentoring, and networking events.
Curriculum and Learning
Trinity Grammar follows the NSW curriculum through Years K-12, with:
- IB Primary Years Programme (PYP) — at the Junior School, including a PYP Exhibition culminating experience
- NSW Higher School Certificate (HSC) — for Years 11-12 in the Senior School
- Trinity Learning Pathways — personalised learning with extension, enrichment, and support programmes
- Term-long Year 9 outdoor education programme at Woollamia — a signature experience emphasising resilience and growth
- Co-curricular programme: sport (mandatory for all boys), music, drama, debating, community service, and overseas study tours including Water Polo tournaments with Australian and New Zealand teams
The school’s educational philosophy is grounded in the belief that challenges, setbacks, and the ability to learn from mistakes are as valuable as academic achievement — “not because all of these teach boys how to succeed, but because they teach them how to fail, how to persevere, how to engage with others, how to grow.”
