DA Form 2166-9-1, NCO Evaluation Report, SGT is a U.S. Army form used for rating and evaluating Non-commissioned officers (NCOs) after their promotion to Sergeants (SGT) including promotion to SGT following a reduction. This form is one of the several Army performance evaluation reports in the DA 2166-9 series. The form requires an evaluating officer and a senior rater to provide their assessment of the NCO's yearly performance and potential. An evaluation by a supplementary reviewer can be added if required.
The latest version of the form - sometimes mistakenly referred to as the DD Form 2166-9-1 - was issued in November 2015 by the Department of the Army (DA). An up-to-date fillable DA Form 2166-9-1 is available for download below or can be found on the Army Publications Directorate website.
