In November 1851 the signing of a Deed of Conveyance with the Board of Manufactures on behalf of Parliament made the Society collections National Property.
It draws on a wide range of experience through the Fellowship, and provides a voice for Scotland's heritage independent of the opinions of Government, University, or Agency.
The Society is consulted by a wide range of organisations from central government to academic funding bodies such as the Arts & Humanities Research Council.
The Society makes written responses to numerous consultations, some jointly with Archaeology Scotland (formerly CSA) and the Scottish Group of the Chartered Institute for Archaeologists.
The Society worked closely with the Historic Environment Advisory Council for Scotland (HEACS was abolished by the Public Services Reform (Scotland) Act 2010 as part of the Scottish Government's policy to simplify the landscape of public bodies), and gave evidence to their working groups on heritage protection legislation and properties in care.
Fellowship recognises a person's support and contributions to the purpose and mission of the Society, and Fellows are permitted to use the post-nominals FSAScot (NB Not FSA (Scot) or similar).
Elections are held biannually at the Anniversary Meeting (AGM) on St Andrew's Day, 30 November, and in Spring, usually in April.
