Authorized by Congress on July 6, 1960, with the creation of the other medals of the Air Force. The medal was not created until June 1, 1963 when the Secretary of the Air Force established it. It is awarded to Air Force enlisted personnel for exemplary conduct during a three-year period of active military service, (or for a one-year period of service during a time of war). Persons awarded this medal must have had character and efficiency ratings of excellent or higher throughout the qualifying period, including time spent in attendance at service schools, and there must have been no convictions of court martial during this period. Air Force personnel who were previously awarded the Army Good Conduct Medal and after June 1, 1963 qualified for the Air Force Good Conduct Medal could wear both medals.
