The Imperial Service Medal (ISM) is a medal affiliated with the Imperial Service Order. The medal was established under the statutes of the Imperial Service Order, on 8 August 1902, by King Edward VII,[1] with the first awards appearing in the London Gazette in May 1903.[3]


It is presented to selected civil servants who complete at least 25 years meritorious service, upon their retirement. It is primarily an award for manual and administrative-grade civil servants, including clerks, workers in H M Dockyards and, prior to 1969 when it moved from central government control, the Post Office.[4] Prison officers were eligible prior to the establishment in 2010 of the Prison Services Long Service Medal.[5] The minimum period of service was 20½ years in India prior to independence in 1947, and 16 years in unhealthy climates in other countries.[4]


When originally created the Imperial Service Medal was a seven-pointed star, or a laurel wreath for women, in the same pattern as the Imperial Service Order, but with the star or laurel in bronze.[6] In 1920 an amendment of the statutes changed the appearance of the medal to its current form: a circular silver medal, 32 mm (1.3 in) in diameter, bearing the effigy of the reigning sovereign on the obverse.[7] To date, here have been six versions:[8]

The reverse bears the image of a naked man resting from his labours[8] with the inscription "For Faithful Service".[7][9] The name of the recipient is impressed on the rim of the medal. Recipients are listed in the London Gazette.[10]
