I created the diagram below to illustrate the different career paths of a Jedi (in the time of the Galactic Republic) [Click to Enlarge]:
|The Jedi Career Path|
If a Jedi Padawan passed the Jedi trials and became a Jedi Knight, he/she could join one of three branches: Jedi Guardian (typically blue lightsabers), Jedi Consular (typically green lightsabers), or Jedi Sentinel (typically yellow lightsabers).
From an educational perspective, the Jedi career path is a good example of apprenticeship learning: An initiate becomes part of a community of practice, mentored by a practicing master who assigns increasingly more challenging tasks, and learns from observing the master in action. Such situated learning is often used in trades, music, martial arts and other sports.
