Trinity Grammar School is an Anglican, non-selective independent school for boys. With a proud history dating back to 1913, Trinity delivers a high-quality education across multiple campuses: the Preparatory School (Pre-Kindergarten to Year 6) in Strathfield, and the Junior School (Kindergarten to Year 6), Middle School (Years 7 to 9), and Senior School (Years 10 to 12) at Summer Hill. Its mission is to provide boys with a thoroughly Christian education in mind, body, and spirit.
Trinity cultivates curiosity, character, and a deep understanding of the world, guided by faith, knowledge, and compassion. Trinity offers a rich and diverse educational experience that fosters academic achievement, spiritual growth, co-curricular engagement, and personal development. At Trinity, every boy is known, valued and challenged to grow. The learning environment is inclusive and supportive, drawing students from a wide range of cultural, geographic and faith backgrounds. Dedicated educators partner with families to nurture boys into young men of character, purpose and confidence.
Trinity’s rigorous and engaging academic program is delivered by passionate and expert teachers who seek to understand each student’s unique learning journey. From Pre- Kindergarten through to Year 12, Trinity provides a broad curriculum that encourages curiosity, critical thinking, and creativity. It is committed to providing world-class facilities that support contemporary learning. Specialist centres for Music, Science, Drama, Visual Arts, Design and Technology, multimedia production, and languages enrich the academic and co-curricular experience.

The Renewal Project currently underway at the Summer Hill campus will see the construction of a new four-storey building featuring adaptable learning spaces, a modernised Arthur Holt Library, and a reimagined Reception and administration hub — designed to support Trinity’s long-term educational vision.
