In this structure, the members of a guild were divided into a hierarchy of masters, journeymen, and apprentices. The master was an established craftsman of recognized abilities who took on apprentices; these were boys in late childhood or adolescence who boarded with the master’s family and were trained by him in the elements of his trade. The apprentices were provided with food, clothing, shelter, and an education by the master, and in return they worked for him without payment. After completing a fixed term of service of from five to nine years, an apprentice became a journeyman, i.e., a craftsman who could work for one or another master and was paid with wages for his labour. A journeyman who could provide proof of his technical competence (the “masterpiece”) might rise in the guild to the status of a master, whereupon he could set up his own workshop and hire and train apprentices. The masters in any particular craft guild tended to be a select inner circle who possessed not only technical competence but also proof of their wealth and social position. Encyclopeadia Brittanica.
