In 1984 a group of dedicated Christians from various denominations came together to share their vision for a Christian secondary school in the Adelaide Hills.

This vision culminated in the joining of the original group with the Lutheran Church to establish Cornerstone College.

Six years later, in 1990, the College commenced operations with 49 students, six staff and a collection of temporary buildings.

The 16 hectares of magnificent land at Mount Barker now accommodates a student body of over 900 students from Years 7 to 12 as well as an array of specialist built, state-of-the-art facilities.

The original governance of the College included members from Lutheran congregations and other Christian denominations in the Adelaide Hills – and that representation remains today, reflecting the ongoing outworking of the motto “Christ our firm foundation”.

The theological basis of the school is that of the Lutheran Church of Australia and the College operates as part of Lutheran Education Australia.

Staff members, students, families and supporters are encouraged to be vital parts of the Cornerstone community where the gift of love, given to us through Christ, can be shown through the care that we show to each other.

The College is a systemic Lutheran school and is closely associated with three Lutheran Primary Schools in the Adelaide Hills: St Mark’s – Mount Barker, St Michael’s – Hahndorf and Lobethal Lutheran – Lobethal.
