An apprentice is the lowest rank of Craftsman. An apprentice is one who is learning the craft. They are often subdivided by the number of years of study. An apprentice is subject to the authority of a journeyman or master, who instructs him. An apprentice is not considered capable of independent work, but may, with a master's approval, sell their products, in those crafts that produce items. Generally speaking, an apprenticeship lasts 4 or more years, the exact term depending on the Craft and the individual apprentice. Most apprentices eventually make it to journeyman status, and many remain at that level.
