The Presbyterian Ladies' College dates from the foundation of the New England Ladies College at "Smith House" in 1887, offering a secondary education for girls under its Principal, Elizabeth Higgs. In 1910, the New England Ladies' College was bought by Alethea Tendall, who went on to be proprietor and Principal for 28 years, and who renamed it The Hilton School. When Tendall purchased it, the school was operating out of two houses. A group of Presbyterian businessmen purchased the school in 1938, and the following year it came under the financial support of the Trustees of the Presbyterian Church of Australia. Subsequently, the school's name was changed to its current form, The Presbyterian Ladies' College, Armidale. In 1945, of land on North Hill were purchased, and following a fund raising campaign, the foundation stone of the new school buildings was laid in 1960. Since then, several building programmes have extended the facilities to their present form. In late August 2005, due to financial troubles at the College, it was announced that PLC Armidale and the Presbyterian Ladies' College, Sydney, would join to form an alliance, with both schools coming under the executive leadership of William McKeith, the Principal of PLC Sydney. Members of the PLC Armidale Council formed part of the new joint school Council, essentially making the two PLC's true sister schools. The aim of this alliance is to strengthen PLC Armidale through cooperative marketing, a change in management and a stronger financial base. It is also to be of benefit to both schools through student exchanges, accommodation for sporting events or excursions, and a 'country or city' option for prospective students. Both schools will maintain their separate identities in order to preserve the unique histories and traditions that both have developed over many years.
