The Efficiency Medal was a medal of Britain and the Commonwealth awarded for long service in the Territorial Army of the UK, the Indian Volunteer Forces and Colonial Auxiliary Forces. This award superseded the awards to ranks throughout the volunteer forces of Britain and the Commonwealth. The criteria were for a minimum of 12 years service in the Territorial Army with war service and West African peacetime service counting double. Bars for further periods of 12 years were also awarded. The medal was superseded in 2000 by the Volunteer Reserves Service Medal.
The equivalent award for commissioned officers was the Efficiency Decoration.
