An Initiate who successfully completes "fundamental training" is given a second-class education and then undergoes Padawan training under the tutelage of a Mentor (usually 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.
