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

New Mexico requires every individual doing plumbing work to hold a Construction Industries Division (CID) journeyman certificate of competence; the JP Journeyman Plumber certificate is the plumbing journeyman credential, and the JPG Journeyman Plumber and Natural Gas Fitter certificate adds natural gas piping (JG and JPF cover gas fitting and pipe fitting alone). A JP applicant needs two years (4,000 hours) of plumbing experience within the last ten years, files a notarized application and work-experience affidavits with PSI for $75 per classification, and must pass the open-book JP written exam and a hands-on practical exam, each at 75%. Certificates run for three years and JP, JPG, JG and JPF holders complete 16 hours of continuing education (eight on the enforced code) before each renewal. CID reciprocates only the EE-98J electrical journeyman classification, so an out-of-state plumbing license earns no exam waiver, although out-of-state hours count toward the experience requirement. A journeyman may work only while employed by a contractor licensed in the classification (MM-1 or MM-98 for a JP).
