The Public Service Medal was instituted in 1973.
The Medal may be awarded to any person who has rendered commendable public service in Singapore or for his achievement in the field of arts and letters, sports, the sciences, business, the professions and the labour movement.
The Medal, in silver, is in the form of a stylised rosette of undulating folds having, on the obverse side, a disc with a bar to each side upon which a circular shield bearing a crescent and 5 stars is embossed. Below it is a scroll with the inscription "PINGAT BAKTI MASYARAKAT" and 2 laurels. The reverse side of the Medal bears the State Arms.
The Medal is to be worn on the left side of the outer garment suspended by a ribbon. The ribbon is grey with a white centre band and a red stripe to each side.
