St Andrew's College was founded by Rev. Alexander Thomas Thompson in 1917 in the Scottish Presbyterian tradition. It was established to "educate the sons of the Presbyterian and Scottish community of Canterbury" and began with 19 boys and four teachers.' The College transitioned to co-education in stages. Girls were enrolled in the Preparatory School during the 1980s, and in 1991, Rector, Dr John Rentoul, and the Board of Governors approved the decision to allow girls to enrol in the Secondary School. On 31 October 2008, students and teachers set a world record for the largest school mass dance with a performance of the YMCA.The
2011 Christchurch earthquake damaged a number of buildings, including the Memorial Chapel, and forced the temporary closure of the Arts Block and Strowan House. Damage to boarding facilities led to boarders being relocated while repairs and strengthening work were completed. The renovated and strengthened Preparatory School was officially reopened by the Governor-General, Sir Jerry MateparaeIn February 2012. As part of the post-earthquake redevelopment, the old MacGibbon and Thompson boarding houses were demolished. In March 2013, new boarding houses – Rutherford (Senior boys, Years 11–13) and Thompson (girls, Years 9–13) – were formally opened by the Right Honourable John Key, Prime Minister of New Zealand. Further facilities work followed. In 2014 the old Rutherford/Erwin house was demolished to make way for a second gym, and new hockey and netball courts were completed alongside an upgrade of the rugby field.
