Ensign was a commissioned rank, the equivalent of which was used by the service organizations of many civilizations. As a traditional naval grade, ensign was the most junior line officer rank below the lieutenant grades, usually immediately under lieutenant or lieutenant junior grade.
Duties and responsibilities Edit
An ensign's primary duty was professional growth, both as a leader and as an occupational specialist. Ensigns were mentored by more senior officers as well as their (nominally) subordinate chief petty officers as part of their development as Starfleet leaders. (DS9: "The Ship", "Starship Down") As ensigns proved themselves more capable, they were considered for promotion into the lieutenant tier. (TNG: "Datalore")
On some of the larger starship classes, such as the Galaxy-class starships, it was not uncommon for veteran and seasoned enlisted personnel to have ensigns working for them as technicians, thus having the ensign "learning the ropes" of the more technical aspects of starship design, such as transporter components. (TNG: "Clues")
The 22nd century Starfleet denoted ensigns with a single rank pin. During the 2250s and 2260s, Federation Starfleet uniforms showed no insignia for ensigns. (ENT: "Broken Bow"; TOS: "The Cage", "Court Martial")
By the 2270s, ensigns were granted the former insignia of lieutenant junior grade, the lieutenant jg rank itself having been discontinued. (Star Trek: The Motion Picture) By at least 2278, ensigns wore a single pin shaped like a stylized "v" letter. (Star Trek VI: The Undiscovered Country)
The late 23rd century pin insignia was used until at least the 2320s. (TNG: "Tapestry") By the end of the 24th century, Starfleet ensigns were once again indicated by one single rank pin. (TNG: "Encounter at Farpoint")

Background information Edit
Star Trek has often portrayed ensigns as background characters who stand watches at bridge stations, serve as nameless security guards, or who get killed or eaten by the alien creature of the week (see "redshirt"). The characters of Wesley Crusher and Pavel Chekov were the first ensigns to be seriously explored with their duties and responsibilities mainly confined to learning and professional growth as officers. The episode TNG: "Lower Decks" also dealt with ensigns and what their daily duties consisted of.
Starfleet ensigns were rarely seen in command of others, one exception being when Ensign Chekov leads a security detail in TOS: "And the Children Shall Lead" or when Wesley Crusher was assigned to lead a science team in TNG: "Pen Pals". In the real United States Navy, however, ensigns have much more responsibility and typically are in charge of divisions consisting of seven to fifteen sailors. In the case of prior enlisted ensigns, or "mustang ensigns" as they are called, it is not unheard of for an ensign to serve as a department head.
Occasionally, older characters have been seen as ensigns, an example of which is Jana Haines, who appears as an ensign but seems to be in her late 30s or early 40s, as well as ensigns Davies and Alans who hold the rank of ensign while serving as science officers with obvious graduate level education. Several other medical and science ensigns from Star Trek: The Next Generation (and later series) have also appeared whose age and experience indicates that they are obviously not recent Starfleet Academy graduates. This gives rise to the possibility that Starfleet, much like the United States Navy, has commissioning programs for prior enlisted personnel or for civilian doctors and scientists who wish to join Starfleet.
In the alternate reality, Leonard McCoy came out of Starfleet Academy as a lieutenant commander. This is also a common practice by the current armed forces, i.e. to give this elevated rank to highly specialized professions (doctors, lawyers, etc.).
After his character's promotion on the show, Gene Roddenberry gave Wil Wheaton the second lieutenant bars he earned in the Army Air Corps (second lieutenant being equivalent to an ensign in the US Navy). Present at the ceremony was General Colin Powell, chairman of the Joint Chiefs of Staff, who later became Secretary of State. (Star Trek: The Next Generation Companion)
In the background/special features section of the Star Trek: The Next Generation DVD set, actor Wil Wheaton stated that he had received Roddenberry's "gold ensign bars" from World War II; however, since Roddenberry's service was in the Army Air Corps, and not the Navy, Roddenberry's insignia were actually second lieutenant bars.
Mentioned in several non-canon novels and other publications is a junior rank known as "Ensign junior grade". The character of Miles O'Brien was suggested to have held this rank, specifically in the novelization of the "Emissary". In the historic United States Navy, a rank known as "Passed Midshipman" existed in the early 20th century intended for recent Naval Academy graduates who had yet to qualify for a position at sea.
