The Air Force on Thursday announced 1,026 enlisted airmen have been selected for supplemental promotion.

According to an Air Force Personnel Center release, 448 airmen were selected for promotion to staff sergeant and 305 were selected for promotion to technical sergeant. There were also 239 airmen chosen for promotion to master sergeant, and 34 selected for senior master sergeant.

AFPC said airmen are considered for supplemental promotion if they are unable to test during their normal testing window, such as if they are deployed at the time, and if they test after the standard promotion selections were made.

AFPC said it told the senior raters of selectees, or other officials in their organization, that their airmen had been chosen 48 hours before the announcement was publicly made.
