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

The written exam has 70 questions in 185 minutes covering drainage, waste and vents, water supply, backflow prevention, storm drainage, fixtures and water heaters, general regulations, interceptors and traps, isometric analysis, and septic and sewer; allowed references include the 2015 New Mexico Plumbing Code (14.8.2 NMAC), the 2021 Uniform Plumbing Code and the 2015 New Mexico Mechanical Code. The practical is scored out of 100 points in 120 minutes and includes copper and PEX water piping with an air test, a tub drain with a water test, a washer box, an island vent, a drainage pipe project, and fitting and tool identification. Experience counts only if it was gained with a contractor licensed in the trade or was legal work where it was performed; PSI reviews military, out-of-country and homeowner experience case by case. After approval you must pass the exams and submit the score reports within six months, you may not take the same exam more than twice in 30 days, and passing scores are valid for one year. The application asks about child support compliance and disqualifying felony convictions (14.6.3.8(F) NMAC), which can be grounds for denial. A journeyman may work only when employed by a contractor licensed for the work, such as an MM-1 or MM-98 licensee. The JG natural gas fitter and JPF pipe fitter certificates are separate classifications with their own exams, and the JMG medical gas installer endorsement is added to a JP, JG, JPG or JPF certificate after separate medical gas certification (14.9.5 NMAC).
