The Australian College of Theology was established in 1891 by the General Synod of the Church of England in Australia. The Australian College of Theology exists as a partnership between the Anglican Church of Australia and a confessionally diverse, national network of 17 Bible and theological colleges delivering the awards of the College on its behalf. This relationship is given expression in the ACT's Institutional Approval Procedures and a Memorandum of Understanding signed by each affiliated college and the Board of Directors, which is the governing body of the College. On 25 October 2007, the General Synod of the Anglican Church of Australia made the Australian College of Theology Canon 2007. The Schedule of this Canon was the Constitution of the Australian College of Theology Limited ('the College'), A Public Company Limited by Guarantee.
Today the College offers a wide range of accredited higher education awards catering not only for the specialised needs of ministerial and missionary candidates but also for the needs of lay people interested in an understanding of the Christian faith and its implications for contemporary life. There are 30 higher education awards and approximately 3,000 active students around the world.
