Our school was founded in 1894 by members of the Presbyterian Church in Ireland. The College was founded to provide a broadly-based, liberal education in the Christian tradition for the sons of its members and those of other parents who wished their children to attend. From its inception, the College attracted students from a variety of backgrounds and strove to unite them through a shared experience of working, learning and playing together.

Today St Andrew's College is a large, inter denominational, co-educational College, with a flourishing junior and secondary school. The College offers a wide range of academic programmes; the Primary curriculum, the Junior Cycle, Transition Year, Leaving Certificate and the International Baccalaureate Diploma at secondary level. The College also offers a wide range of co-curricular, sporting, creative, cultural and other extra-curricular activities.

Since 1984 St Andrew's College has been fully accredited by both the Council of International Schools and the New England Association of Schools and Colleges, and the International Baccalaureate. When founded St Andrew's College was, in effect, an 'integrated’ school and it remains so today.
