The Sisters of Mercy founded St Catherine’s College in 1950. It became integrated into the State School system under the Private Schools Conditional Integration Act in 1975. The size of the school contributes to a family atmosphere, creating a strong sense of belonging and community amongst students. Girls are educated through the vision of Catherine McAuley, the founder of the Sisters of Mercy, in Catholic social teachings that underpin the Special Character of the college. Students at all year levels have opportunities to be of service and/or act for justice.
