An Enlisted Performance Report (EPR) is an evaluation form used by the United States Air Force. Instructions for constructing an EPR appear in chapter 3 of Air Force Instruction 36-2406: Officer and Enlisted Evaluation Systems. The EPR replaced the Airman Performance Report (APR) in the late 1980s.
The USAF commissioned officer equivalent is the Officer Performance Report (OPR). The United States Navy equivalent is the Fitness Report (FITREP). The United States Army equivalent is the Enlisted Evaluation Report (EER).
An EPR evaluates the performance of an enlisted member both on and off duty. The period of time covered by the EPR is normally no less than 120 days and no longer than 365 days. EPRs are normally written by the member's supervisor with additional input provided by their supervisor's supervisor.
Although the bulk of the evaluation is focused on their duty (job) performance, enlisted members are also evaluated on their off-duty performance in areas such as volunteerism and continuing education. This is arguably the biggest difference between the Air Force EPR and civilian counterparts.
Personnel who have left the Air Force and are seeking jobs in the civilian world will sometimes use EPRs to augment their résumé.
Stratification is the "rack-and-stack" process senior raters use to identify their top promotion-eligible master sergeants and senior master sergeants. Senior raters are limited to stratifying the top 10 percent of their master sergeant promotion-eligible Airmen and the top 20 percent of their senior master sergeant promotion-eligible Airmen. Promotion-eligible senior NCOs who are not stratified will have their evaluations close out at the deputy evaluator (first O-6) or intermediate evaluator (unit commander) level. Only those who are stratified will have their evaluation signed/closed out by the senior evaluator (senior rater).
Stratification statements must be stated in quantitative terms (#1 of 125 MSgts) and will be based on the number of peers (in the same grade as the ratee) assigned within the evaluator's rating scheme. Stratification statements on all other performance reports, to include CMSgt reports, are strictly prohibited.
