North Dakota records apprentices on its own plumber licence register as Plumber Apprentice 1st Year: 851 active apprentice-tier records against 911 journeyman records, a ratio of 0.93 apprentice records per journeyman, register read September 16, 2026. The register's apprentice tier and the federal registered-apprenticeship count in the county table are two different systems: a licence-register apprentice is anyone the state has credentialed to work under supervision, a registered apprentice is enrolled in a DOL-registered program.
Counts are license records, not people: a holder with more than one license appears once per license, and a contractor license is a business, not a worker.
