how long to put on sra from a1c
Senior airman The Air Force promotes an Airman First Class (A1C) to Senior Airman after 36 months time in service (TIS) and 20 months time in grade (TIG), or 28 months TIG, whichever occurs first. Outstanding Airmen First Class, limited to no more than 15 percent of the total, may be promoted to Senior Airmen six months early, in a competitive process called Below-the-Zone, which normally involves going before a competitive board. Senior Airmen are expected to be technically proficient and begin to develop leadership skills, and may be expected to supervise an Airman of lesser rank.
