In a command with over 650 Sailors, who serves as the reporting senior on performance evaluations for Sailors E-1 through E-6?

In a command with over 650 Sailors, the appropriate reporting senior for performance evaluations of Sailors E-1 through E-6 is both the Commanding Officer and the Executive Officer. This is established in the Navy's performance evaluation regulations, which outline that for commands of this size, the Commanding Officer has the overarching authority but delegates some evaluation responsibilities to the Executive Officer.

The dual involvement ensures comprehensive oversight and quality in evaluations, allowing Sailors to receive fair and thorough assessments. This division of responsibility helps manage the potentially large number of evaluations efficiently, as the Executive Officer can address the performance of junior personnel while ensuring adherence to evaluation standards set by the Commanding Officer. In this structure, the combined authority of both leaders fosters accountability and promotes development among the Sailor ranks.

In smaller commands, only one of these leaders might serve as the reporting senior, but in larger commands, the collaborative process between both figures enhances the performance evaluation system's effectiveness and reliability.
