Journeyman and master titles, licensing boards, experience requirements, and exams are not uniform nationwide. Some credentials are issued by cities or counties, and some jurisdictions do not use a master-level license. Apprenticeship offices oversee apprenticeship programs; they are not necessarily licensing boards. Verify all requirements with your state or local authority before applying.
