Jedi Ranks
Youngling: A Jedi Youngling is a child, a Jedi-in-training, learning to control the Force and wield a lightsaber. The title of "Youngling" is the first part of Jedi training. Younglings were seen training under Jedi Master Yoda in a scene on Attack of the Clones and hiding during the assault on the Jedi Temple in Revenge of the Sith.
Padawan: A Youngling who successfully completes training then undergoes Padawan training under the tutelage of a Jedi Knight or Jedi Master. They are also called "Apprentices" and "Padawan learners". As a rite of passage and the final test before the trials to knighthood, Padawans must build their own lightsabers. In the Old Republic, Padawans usually wore a hair braid on the right side of their head which was removed with a lightsaber upon attaining knighthood. They also served as Commanders in the Clone Wars. The term Padawan appears to originate in Sanskrit and can be understood as “learner," both in Sanskrit and by contemporary native speakers of Sanskrit-based languages.
Jedi apprentice: After learning as a padawan, the next step in becoming a knight is to be an apprentice of a master. in this stage there will be tests for the jedi to overcome. then here will be a final trial to be a jedi knight.
Jedi Knight: Disciplined and experienced, Jedi Knights become so only when they have completed "the trials" (final tests). This, the most common rank, is interchangeably referred to as "Jedi", "Jedi Knight" and "Master Jedi" (although the latter only used by Younglings and Padawans when addressing Jedi Knights or above). The five tests are usually known as Trial of Skill, the Trial of Courage, the Trial of the Flesh, the Trial of Spirit, and the Trial of Insight or Knowledge. In Return of the Jedi, Master Yoda gives his apprentice, Luke Skywalker, the trial of confronting Darth Vader for a second time so he might become a full-fledged Knight. Occasionally, performing an extraordinary (usually heroic) act can earn a Padawan learner Jedi status, such as when Obi-Wan Kenobi defeats the Sith Lord Darth Maul. By the time of the movies distinct battle classes were not necessary
