WHAT DID EACH OF THE STEPS INVOLVE IN BECOMING A MEMBER OF A GUILD?
Apprenticeship- working for a guild master for a number of years in exchange for food, a place to sleep, and education.
Journeyman- working at the trade for a number of years, usually as a paid employee of a different master.
Master- the journeyman prepared a masterpiece, which was designed to show off his skill. The masterpiece was judged by a jury of masters of the guild, and if they agreed that it showed mastery, then the journeyman would be a master.
An apprentice/journeyman/master paradigm is daily in tact for the feature film, feature animation, and television production industries. Generally film school graduates will start in the same position as someone hired with no previous experience. As they bounce from production to production they're promoted up the responsibility chain and are generally hired as crew for people they've worked under before.
