John Colet School is a multi-faith co-educational infants and primary school which was founded in 1985, in a terrace house in North Sydney, by men and women studying together at the School of Practical Philosophy in Sydney.

The school motto is Testare De Illa Luce – latin for Bear Witness of That Light. It is the aim of the school to nurture the light of intelligence, love and truth which is the birthright of every child. We therefore seek not only to provide a thorough and sound education, but also to build character, and to give the children a strong philosophy of life and an understanding that service, truthfulness and consideration for others lead to a happy, fulfilled and effective life.
