The skill level indicated by the fifth character in an AFSC typically represents what?

The fifth character in an Air Force Specialty Code (AFSC) typically indicates the master level. In the structure of the AFSC, the fifth character is designated to denote a person's advanced level of expertise and experience within their specific field. This character signifies that the individual has not only completed the required training but has also acquired significant practical experience, demonstrating a high proficiency in their duties.

At the master level, personnel are expected to perform their tasks independently and may also be involved in mentoring less experienced airmen or leading specific projects within their specialty. This proficiency reflects a deeper understanding and capability that surpasses the journeyman level, where one is competent but not yet at the mastery stage.
