A journeyman's card shows that a professional in a particular trade has passed the examination necessary for journeyman status. Such fields as electrical work require a number of different examinations for the journeyman and master cards, according to Clark County, Nevada.
While passing the examination is enough to earn the card, practitioners often have to complete continuing education in order to retain the cards. In fields that require city, county and/or state permits for inspection, requirements often mandate that professionals with a journeyman or master card complete the work. These rules are designed to promote overall safety, as stated by Clark County, Nevada.
