A Change of Duty NCOER is mandatory in which scenario?

• A. When promoted.
• B. When a rated Soldier is reassigned to a different principal duty while still under the same rater.
• C. When deployed on temporary duty.
• D. When retired.

Answer: (B)

A Change of Duty NCOER is required when a rated Soldier moves to a different principal duty while the same rater remains in place. This ensures the assessment accurately reflects performance in the new role, without the previous duties clouding the evaluation. If the Soldier changes duties but the rating official stays the same, a dedicated Change of Duty NCOER records the transition and the new responsibilities, giving a clear, apples-to-apples view of performance in the current duty.

The other scenarios don’t automatically trigger this type of report. Promotion changes rank but not necessarily the principal duty or rating official, so it isn’t by itself a Change of Duty NCOER. Deployment on temporary duty doesn’t inherently switch principal duties under the same rater, so it doesn’t mandate this form. Retirement ends service, so there isn’t an ongoing evaluation to document.
