Enlisted duty titles are primarily assigned according to which criteria?

Enlisted duty titles are primarily assigned based on the scope of responsibilities and duties performed. This criterion reflects the specific functions and roles that enlisted members fulfill within their units, aligning their titles with the level of expertise and responsibilities inherent to that position. This approach ensures that duty titles accurately represent the capabilities and roles of service members, providing clarity about their expected contributions to the mission.

While years of service, performance ratings, and training and certification achievements may influence career progression and responsibilities, they do not directly dictate the assignment of duty titles. Instead, the focus is on the nature of the tasks and responsibilities expected from the member in their role, ensuring that titles are descriptive of their actual duties.
