Youngling
From the Encyclopedia of Speculative Fiction - http://encyclopedia.wizards.pro
Youngling was an unofficial title, referring to a Force-sensitive child undergoing the early stages of Jedi training - otherwise known as a Jedi Initiate. At a very young age, they were removed from their home and assigned to a Clan (such as the Bear Clan or the Katarn Clan) for training. Although the term "youngling" was usually used to refer to these young Jedi-in-training, the term "youngling" was actually Galactic Basic slang for "children."
If a Youngling was not chosen by any Jedi Knight to be their Padawan by 13 years of age, the youngling was placed into another, lesser role in the Jedi Service Corps. Depending on where the student's talents lie, this could have been the Agricultural Corps, the Medical Corps, or the Exploration Corps.
