What must be included in the duty description section of the NCOER?

The correct choice emphasizes the importance of providing a clear and accurate description of the NCO’s duties and responsibilities in the duty description section of the Non-Commissioned Officer Evaluation Report (NCOER). This section is critical as it serves to outline the specific roles the NCO is expected to fulfill, detailing their scope of work and the expectations associated with their position.

Including a precise description allows evaluators and future leaders to understand the context of the NCO's performance during the evaluation period. It sets the foundation for assessing the NCO's competencies, effectiveness, and contributions to their unit. By accurately capturing the duties and responsibilities, it helps ensure that evaluations are fair and reflective of the NCO's actual responsibilities.

Other choices do not belong in the duty description section. Personal achievements, recommendations for future assignments, and training completed, while important, are typically documented in different sections of the NCOER. They contribute to the overall evaluation but do not define the specific duties the NCO is responsible for in their current role.
