Metro boundaries follow the same CBSA geography used elsewhere on Prentice, so a city list can be compared with wage, market-pressure, and local guide pages.
Public rows require verified status, at least one supporting source, and a usable phone, website, email, or training contact. Uncertain rows stay out of the city list.
Prentice uses the reader-facing phrase local guild for the local union, district council, or training trust that can point an applicant toward the apprenticeship path.
Records without live-confirmed contact paths are held back. Some broad regional councils also need a second pass before they can be mapped confidently to every covered metro.
Apply through the local union, JATC, training trust, or state apprenticeship sponsor. Prentice helps locate the right office and website; intake rules still belong to the sponsor.
