A contract between two parties, one of which is usually a minor (the “apprentice”) who is bound to the other person (the “master”) to serve him for a stated period of time, during which the master agrees to teach the apprentice an art, skill, or trade while providing complete maintenance. The agreement may include a grant of money, clothing, and/or property upon completion of the term.

On completion of an apprenticeship, an apprentice might become a Journeyman, although in early colonial America that term was not prevalent -- the apprentice simply became a paid servant.
