In peacetime, a Lieutenant (Junior Grade) would have served two years as an Ensign and been reviewed by a Officer Promotion Board. However, promotion is almost always confirmed. They will have also completed initial training from warfare or staff specialties. 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 board for promotion.
