Final answer:
The rater or senior rater is responsible for ensuring the completed NCOER reaches HQDA and the Rated NCO. The NCOER is pivotal for the career progression of noncommissioned officers and is managed according to Army Regulation 623-3.
Step-by-step explanation:
The person responsible for ensuring that the signed and completed NCOER (Noncommissioned Officer Evaluation Report) is provided to HQDA (Headquarters, Department of the Army) and the Rated NCO (Noncommissioned Officer) is typically the rater or the senior rater.
After completion and verification of the NCOER, it should be forwarded through the proper channels to reach HQDA. The rated NCO will also be provided a copy of the final, signed report for their own records and future reference.
It is critical for this process to be handled correctly as the NCOER plays a significant role in the career development and progression of noncommissioned officers. The administration of the NCOER is dictated by Army Regulation 623-3.
