St Andrew's College is supported by two important groups, The St Andrew's College Alumni Society and the St Andrew's College Foundation.
The St Andrew's College Alumni Society is the association of past students of St Andrew's College. The Society was formed in 1948 to promote the well being of the College and to assist in the maintenance of contacts between Alumni of all ages.
The Society holds an annual dinner in College in November/December and provides three scholarships for the benefit of students.
The St Andrew's College Foundation Limited is a non-profit company limited by guarantee which, together with a Trust, was established by the College Council in 1985 to build a corpus of assets, the income from which will be used to ensure that St Andrew's College remains, proud and independent, well into its second century and beyond.
The Foundation is governed by its own Board of Management independent yet beholden to its Members and to the College Council. It consists of those who have been elected by their peers and those who have chosen to sit on the Board by virtue of their generosity.
