Moving to Maine as a journeyman plumber: every state's rule

Maine issues a statewide Journeyman Plumber license through the Plumbers' Examining Board in OPOR (32 M.R.S. ch. 49). By examination an applicant files a sworn application, pays the fee set under §3501-B, documents at least two years / 4,000 hours as a licensed trainee plumber under a master (or the equivalent), or 2,000 hours as a journeyman-in-training under a master within four years of the JIT license, and obtains a passing grade on the board-approved journeyman examination. The board also issues a one-time, four-year nonrenewable journeyman-in-training license after one academic year of approved plumbing instruction plus the same exam, a limited plumber license, and a trainee plumber license without examination. Out-of-state journeymen are directed to licensure by endorsement under 32 M.R.S. §3501-C and 10 M.R.S. §8003-H when the origin jurisdiction's requirements are substantially equivalent; otherwise they apply by examination with comparable hours credited as 'the equivalent' of Maine trainee time.
