Missouri plumbing licensing answer: there is no single statewide Journeyman Plumber exam. Springfield uses the ICC W25_MO_S exam based on the 2018 IPC, while Kansas City uses the ICC 675_MO_KC Journeyman Plumber with Gas exam based on the 2018 UPC and 2018 IFGC.
How Does Missouri Journeyman Plumber Licensing Work?
Missouri Journeyman Plumber licensing is handled primarily by local jurisdictions. That means the exact exam, code book, reference set, passing requirement and licensing process depend on the city or county where you plan to work.
Springfield and Kansas City are useful examples because both publish 70-question, 3-hour open-book exams, yet the code books and exam blueprints are very different.
Springfield: ICC W25_MO_S | 70 questions | 3 hours | open book | 2018 IPC.
Kansas City: ICC 675_MO_KC | 70 questions | 3 hours | open book | 2018 UPC + 2018 IFGC.
Licensing strategy: always verify your local municipality before purchasing books or scheduling an exam.
A Missouri journeyman plumber credential is an individual trade qualification. A plumbing contractor credential is generally a separate business license and may require a master plumber or other qualified supervisor, depending on the jurisdiction.
