The NASCLA Route to a Missouri Electrical License

Updated September 2026

Missouri is one of the 17 licensing boards in the NASCLA electrical program that recognize the Master/Unlimited exam - the same standardized 100-question, open-book test everywhere it is used.

Here is exactly what the NASCLA electrical exam covers with the Missouri Office of Statewide Electrical Contractors (Division of Professional Registration), what Missouri still asks of you on top of it, and the details that trip people up.

What the NASCLA exam covers in Missouri

The exam requirement for Missouri's statewide electrical contractor license (created 2019) - PSI runs the NASCLA examination program for the office.

What Missouri still requires

Passing the trade exam is necessary, not sufficient. You still need verifiable experience (12,000 practical hours, with lower tiers down to 4,000 hours plus an electrical engineering degree), $500,000 liability insurance, and bonds with each political subdivision where you work.

Watch-outs and fine print

Missouri's statewide license is optional - local licensing still exists - but one statewide-licensed supervisor covers the whole company, which is why contractors get it.

There is no separate Missouri business-and-law exam on the statewide path.

Always confirm with the board

Licensing rules change and boards update their bulletins without notice. Before you schedule anything, confirm the current requirements at pr.mo.gov - it takes ten minutes and prevents expensive surprises.
