How to Become an Electrician in Missouri
Missouri licenses journeymen city by city, and the cities don't even agree on the structure — St. Louis issues journeyman and master licenses, while Kansas City skips journeyman entirely and starts at master. Since 2019 there's also an optional statewide Electrical Contractor license so you can contract across Missouri without collecting a license in every town.
Licensing in Missouri at a glance
- How it's licensed
- Local / municipal — no statewide journeyman license (optional state contractor license)
Where you're licensed — Your city or county, and the structure varies:
- St. Louis — issues both journeyman and master licenses.
- Kansas City — has no journeyman license; it starts at master, with Class I (unlimited) and Class II (limited to existing circuits) master classes.
Experience — A typical apprenticeship runs four to five years (about 8,000 hours) plus classroom instruction, through IBEW/NECA or ABC/IEC programs.
Optional statewide Electrical Contractor license — Introduced in 2019; lets you contract across Missouri without a separate license in each jurisdiction.
A city-by-city patchwork
Missouri is a local-licensing state, and it's one of the more uneven ones. There's no statewide journeyman or master license, and the two big cities don't even structure it the same way: St. Louis issues journeyman and master licenses the way you'd expect, while Kansas City has no journeyman license at all — it begins at master, split into Class I (unlimited) and Class II (limited to existing circuits). So the very first question is where you'll work.
The 2019 statewide option
To cut down the confusion, Missouri added an optional statewide Electrical Contractor license in 2019. It doesn't replace local licensing, but it lets a contractor work across the state without chasing a separate license in every city — genuinely useful if you'll operate regionally.
The training is standard
Whatever city you land in, the apprenticeship is the usual four to five years — roughly 8,000 hours of field work plus classroom instruction — through a union (IBEW/NECA) or non-union (ABC/IEC) program.
Your next step
Pick where you'll work and contact that city for its requirements (and note whether it even has a journeyman tier). Get hired to start your apprenticeship hours, and if you'll contract regionally, look at the statewide Electrical Contractor license. The national How to Become an Electrician guide covers the trade overall.
⚠️ Always verify current requirements
Licensing rules change and often vary by city or county. Before you count on anything here, confirm the current requirements directly with Local municipalities; optional statewide Electrical Contractor license (Division of Professional Registration).
