Who is eligible to use the JEPES system?

The correct answer indicates that the JEPES system is specifically designed for enlisted personnel ranked E-1 through E-4. This group typically includes junior enlisted members such as Privates, Privates First Class, and Corporals. The system focuses on establishing a performance evaluation framework tailored to the needs and duties of these junior ranks, allowing for an assessment that is relevant to their roles and responsibilities within the military.

The other choices do not apply because the JEPES system is not intended for officers, civilians, or staff members across ranks. Officers generally have their own evaluation systems tailored to their specific leadership and operational expectations, while civilians, despite being involved with the military, are assessed using a different framework that aligns with civilian employment standards. Additionally, including any staff member across ranks dilutes the specific focus of the JEPES system, which aims to maintain a standardized and relevant approach for junior enlisted personnel.
