If you want to start a plumbing career in Missouri, the first step is getting the right training. Plumbers work in a skilled trade that requires hands-on knowledge of piping systems, safety codes, and tools. Missouri does not have a single statewide plumbing license, but several cities and counties set their own licensing requirements. That means your training program needs to prepare you for real-world work and local exams.
This guide covers the best plumbing schools in Missouri, what each offers, and the basic steps to getting licensed.
How to become a plumber in Missouri
Getting into the trade is straightforward, but you need to follow a structured path.
Basic steps:

Meet local licensing requirements - Missouri cities like St. Louis, Kansas City, and Springfield issue their own licenses.
