The latest Officer Evaluation Reporting System (OERS) represents the most substantive change in officer evaluation concept and philosophy since World War II. It incorporates several new features which have not been included in previous officer evaluation reporting systems: rated officer participation, senior rater concept and a senior rater profile. Participation by the rated officer in the evaluation process provides additional information from the rated officer's point of view to rating officials, encourages counseling early in the rating period and enhances the effectiveness of organizations by relating performance to organizational missions. The senior rater concept increases the role of the most senior rating official from a purely administrative role to include a critical evaluation of the rated officer's potential. The senior rater profile provides a comparison of a specific rating and a senior rater's normal rating tendency (e.g., easy or hard) by tracking the rating history of the senior rater and making it visible to selection boards and DA managers.
