The Jedi Order has at least three known ranks.
- Padawan - an apprentice who is learning to use the Force. Apprentices vary in age from early childhood to adulthood, and presumably there is considerable "rank" variation among them as a result.
- Knight - a former Padawan who has passed a test known as the Trials, allowing him or her to operate without supervision.
- Master - a Jedi Knight who has finished training at least one Padawan. It is not entirely clear what sort of authorization a Jedi Knight needs from the Order to take an apprentice.
According to secondary sources, there are three primary roles that Jedi pursue.
- Jedi Guardian - primarily combatants
- Jedi Consular - primarily diplomats
- Jedi Sentinel - primarily scouts, explorers, or investigators
The Jedi Order is commanded by the Jedi Council, which consists of several Master-ranked Jedi. The Order exists to serve the Republic and generally does the wishes of the Supreme Chancellor of the Republic, although such authority usually does not extend to internal matters of the Order, such as the awarding of ratings and the selection of Jedi Council members.
While Jedi are devastating warriors individually, they are not effective in large numbers, having neither the training nor the equipment to function as an army. Their lack of group combat experience was most evident at the Battle of Geonosis, where dozens of Jedi -- who essentially fought as a mob of heroic individuals -- were overwhelmed by the superior numbers, combined arms, and coherent tactics of the CIS's battle droids.
