The teenage years are exciting and full of boldness, creativity and fun; they are also as fragile as they are pivotal. Whilst constantly aiming to inspire through high quality teaching, strong relationships and a wonderfully-equipped environment, Trinity also provides a safe framework within which such energy can thrive.

About the middle and senior school

Boys are supported pastorally through our House System. Participation in a breadth of sporting, creative and performing arts activities promotes a rich cultural ethos and develops the individual talents of each student. A wide-ranging curriculum caters for both the intellectually gifted and those interested in vocational courses, and is arguably the most extensive of non-selective Independent Boys Schools in NSW.
