A teacher could be defined as someone who imparts knowledge to others.
Those who taught combat skills were known as instructors, whereas training officers were responsible for the education of military cadets.
Jedi Knights and Masters had the ability to impart lessons drawn from their experiences within the Jedi Order and across the Galaxy to their Padawans, continuing until the padawan successfully completed the Jedi trials, removed the mark signifying their training, and achieved the rank of knight.
Additionally, Mandalorians educated their foundlings and fellow clan members in a range of disciplines, including Mandalorian historical accounts, artistic pursuits, the craft of metalworking, the maintenance of ships, and the operation of a jetpack.
