How to get promoted to Major Army Promotion to O-4 Major

A Major is a Field Officer in the United States Army at DoD paygrade O-4. This page describes how the Army determines who is eligible for the promotion list to Major.

Promotion to the rank of Major functions the same way as Captains in the sense that it too is competitive and not guaranteed.

In their time serving as Captains, officers are graded on their performance by their commanders (a lieutenant colonel at the battalion level and then a colonel at the brigade level), which grades are recorded in further OER’s, which themselves get added to the OER record the officer has already accumulated.

A Captain who has served a minimum of ten years time in service and six years time in grade becomes eligible for promotion to Major, provided such officers continue to meet the physical requirements and stay out of legal trouble.

The Army automatically generates a slate based on the fulfillment of the requirements for Major. The slate includes all Captains who have met the requirements.

A board selects officers to be promoted to Major based on their career performance so far, determining whether or not they should be promoted based upon demonstrated career performance as recorded in each candidates’ officer evaluation reports (OER’s).
