A Jedi Candidate designated an individual with a sensitivity to the Force, being examined for potential training within the New Jedi Order. However, these candidates were ultimately deemed ineligible to achieve the rank of a full-fledged Jedi due to various disqualifying factors.
One such case was Dyon Stadd. His inability to progress to Jedi status stemmed from the fact that his inherent Force powers did not reach the necessary threshold of strength.
