Rank Promotion Schedule
« on: February 22, 2017, 10:57:35 PM »
Starfleet uses a promotion schedule quite like the US Navy does. The promotion time-in-grade requirements represent the time an officer must spend at a particular rank before the officer becomes eligible for promotion to the next rank. The time-in-grade requirements are progressive, increasing with each promotion. Together with the total time an officer is in service, time-in-grade makes an officer eligible for promotion. Officers recommended for promotion are chosen by a selection board from a pool of all eligible candidates.

Ensign to Lieutenant J.G

Promotion from ensign, the O-2 officer grade, to lieutenant junior grade, O-3, requires an officer to have been in the Navy for not less than two years. This is the time-in-service requirement. Officers who served in the military prior to their commissioning as an officer -- a process known as "frocking" -- satisfy the time-in-service requirement before they are commissioned. However, these officers must have also served two years in the rank of ensign to satisfy the time-in-grade requirement for recommendation to the O-3 selection board for promotion.

J.G. to Lieutenant

As an officer fulfills his duties and obligations and again becomes eligible for promotion, time-in-grade and time-in-service." A lieutenant junior grade, often referred to simply as a "J.G," must have two years service at that rank before being considered for promotion to the rank of lieutenant, O-3. A J.G. must also have a total of four years of military service before the lieutenant selection board will make a recommendation for the promotion to lieutenant.

Lieutenant Commander

Selection for commander -- the O-4 officer pay grade equivalent to a major in the Army, Air Force or Marine Corps -- requires that the candidate for promotion must have served three years as a lieutenant to meet the required time-in-grade. A lieutenant must also have between nine and 11 years of military service. While nearly all ensigns are promoted to lieutenant J.G., and almost 95 percent of lieutenants junior grade, make lieutenant, the O-4 selection board only promotes about 80 percent of eligible officers.


Reaching the rank of commander, O-5, from the rank of lieutenant commander requires an officer to have served a total of three years as a lieutenant commander to meet the time-in-grade requirement. The officer must also have between 15 and 17 years of total military service. The O-5 selection board only promotes about 70 percent of those recommended by their commanding officers for promotion.


Captain, the O-6 officer pay grade, is the highest rank that a naval officer can attain without congressional approval in addition to the presidential approval that's part of commissioning and officer promotion. Before receiving a recommendation for promotion from commander to captain, the officer must have completed three years of service in the grade of commander, to satisfy the minimum time-in-grade requirement. In addition, the captain-selectee must have between 21 and 23 years of total military service before the O-6 selection board meets to consider the promotion. The O-6 selection board chooses approximately 50 percent of the recommended officers for promotion, depending partly on the needs of the service.
