What primary element can influence promotion outcomes at the board?

Peer and superior evaluations are a primary element influencing promotion outcomes at the board because they provide a comprehensive assessment of an individual's performance, leadership qualities, and potential for future roles within the Army. These evaluations offer insights from those who have directly observed and interacted with the individual in a professional context, highlighting strengths and skills that may not be fully captured in formal documentation.

This aspect is crucial because the board prioritizes candidates who not only excel in their duties but also contribute positively to the team and demonstrate the potential to lead others effectively. While other factors such as holistic health reports, participation in additional training, and years of service can have an impact, the subjective and qualitative nature of peer and superior evaluations often carries significant weight in the decision-making process, reflecting an individual's overall readiness for advancement.
