The Karyakshama Seva Vibhushanaya (KSV, Efficient Service Order) (Sinhala: කාර්යක්ෂම සේවා විභූෂණය kāryakṣama sēvā vibhūṣaṇaya) is a medal awarded to commissioned officers of the Sri Lanka Army Volunteer Force. Established on 7 January 1986, it replaced the Efficiency Decoration (Ceylon) with effect from 22 May 1972 with volunteer officers who have completed the stipulated required years of service qualifying to the award. Since 2020, with the Karyakshama Seva Padakkama becoming opened to all ranks, the KSV became limited to award for senior volunteer officers.^[1]

All commissioned officers of the Sri Lanka Army Volunteer Force (including those attached to the National Cadet Corps) who, by or after 22 May 1972, have completed 18 years of excellent service are eligible for the award.^{[citation needed]}

The practice ended in 1972, when Ceylon became the Republic of Sri Lanka after the Republic Constitution was enacted on 22 May 1972.
