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

Colorado issues a statewide Journeyworker Plumber license (its name for the journeyman level) through the State Plumbing Board in DORA's Division of Professions and Occupations; the Board also licenses Residential Plumbers (two years / 3,400 hours) and Master Plumbers, registers apprentices, and registers Plumbing Contractors, which must hold or employ a licensed master plumber. By examination a journeyworker needs four years (6,800 hours) of documented practical experience verified on Affidavit of Experience forms by plumbing contractors or employers, a $120 application fee, and a passing score of 70% on the PSI-administered Colorado journeyworker exam (100 multiple-choice questions, 240 minutes) based on the 2021 IPC/IRC as adopted in 3 CCR 720-1. Out-of-state licensees who meet Board Rule 1.4(B)(1)(a) may instead be licensed by endorsement without the Colorado exam; the Board publishes no reciprocal agreements with any state. Licenses expire on the last day of February of odd-numbered years, and renewal requires eight hours of continuing education per licence year (waived until after the first renewal for new exam licensees).
