DA Form 2166-9-1A, NCOER Support Form is a support form that is used for gathering information during the evaluation of U.S. Army Non-commissioned officers (NCOs) in the rank of Sergeant (SGT). This form is a part of the DA 2166-9 series that contains five other rank-specific performance assessment reports.
The latest version of the form - sometimes mistakenly referred to as the DD Form 2166-9-1A - was issued in November 2015 by the Department of the Army (DA). An up-to-date fillable DA Form 2166-9-1A is available for download below or can be found on the Army Publications Directorate website.
The SGT NCO being evaluated should receive counseling from a senior rater at least twice during the rating period. Having received counseling, the NCO needs to fill out the form providing a self-assessment of their work goals and expectations, along with a personal evaluation or their professionalism, performance, attributes, and competencies. A senior rater can provide additional comments to the self-evaluation, if necessary.
