A journeyman is a trader or crafter who has completed an apprenticeship. A journeyman was a craftsman who had fully learned his trade and earned money but was not yet a master. To become a master, a journeyman had to submit a master work piece to a guild for judgment. If the work were deemed worthy, the journeyman would be admitted to the guild as a master. (Wikipedia).
Wikipedia has some interesting info on the history of apprenticeships in England.
