In 2256, Captain Gabriel Lorca invited Michael Burnham, stripped of rank after a court martial, to join the bridge crew of USS Discovery as a science specialist. (DIS: "Lethe") Burnham's official rank was later restored as part of a pardon, rendering this unofficial rank redundant. (DIS: "Will You Take My Hand?")

In 2267, James T. Kirk told the Organian Council of Elders that the Federation could send them specialists and technicians. (TOS: "Errand of Mercy")

In 2269, Lucien described himself as having been "the generalist amid all the specialists." Asmodeus also described himself as "a specialist in the ethics of magic", which rendered him suitable to serve as prosecutor at the trial for members of USS Enterprise's crew. (TAS: "The Magicks of Megas-Tu")
Later that year, the Vedala sent for several specialists, including Kirk and Spock, for a critical mission. (TAS: "The Jihad")
