Cadet

Cadets are neither officers nor are they enlisted personnel. Cadets still attend Starfleet Academy and only serve on Starfleet ships for training purpose for a limited time period.

The term also applies to attendees of the Starfleet Marine Corps Academy.

The equivalent term in the Federation Starfighter Corps is air cadet. (Star Trek: Remington)

RIS Bouteina[]

Romulan Naval Academy cadets were considered as senior as petty officers (Erei'Erein) on their cadet cruise, even if they served on Romulan Star Navy ships for training purposes for a limited time period.

Also, both the Hydran Royal Navy and the Lyran Starfleet make use of cadets.
