History

This medal was conferred upon Chief Warders, Head Warders and Warders of the South African Prisons Department for distinguished service. It was also awarded for 18 years of impeccable service.

A clasp was awarded for bravery.

This medal was originally known as the "Prisons Good Service Medal" (1922-1959). It was discontinued in 1968 as it was the first of three series of decorations for the South African Prisons Department.

The reverse features an inscription that varies: a) FOR FAITHFUL SERVICE - VOOR TROUWE DIENST (1922-1932); b) FOR FAITHFUL SERVICE - VIR TROUE DIENS (1932-1959); c) VIR TROUE DIENS - FOR FAITHFUL SERVICE (1959-1968).
