Final answer:
An NCO can monitor the status of their submitted NCOER by accessing the Army's Evaluation Reporting System through the Human Resources Command website, where they can view and track the report's progress.
Step-by-step explanation:
The Non-Commissioned Officer Evaluation Report (NCOER) is crucial in assessing an NCO's performance and potential within the U.S. Army. To monitor the status of their submitted NCOER, an NCO can use the Evaluation Reporting System (ERS) that is accessible through the Army's Human Resources Command (HRC) website. Once logged in, they can view the status of their report in the system. This helps the NCO ensure that their evaluation is being processed promptly and addresses any issues that may arise during the evaluation process. It is recommended that the NCO checks the system regularly until the NCOER is finalized.
