The Jedi ranking system occasionally seems a little complex. In general, all Jedi begin as Younglings. As they grow, they are taken under the wing of an older, experienced Jedi as a Padawan, beginning to apply the lessons they learned as youngsters. A Padawan would graduate by completing the Jedi trials to become a Jedi Knight. Eventually, with a deep connection to the Force, they could become a Jedi Master. The single Jedi in charge of the Council and the Order held the rank of Jedi Grand Master. At the time of the Clone Wars, this was Yoda. Padawans always addressed those above them as "Master ..." (even if they were a Knight). In turn, higher ranks always addressed padawans as "Padawan ...". In a couple of non-canonical references, Jedi are referred to simply "Jedi ...".
