Step by step

  1. 1

    Get trained and start logging hours

    Begin documented work experience under a licensed plumber. Keep careful records — the board will want proof of your hours.

  2. 2

    Accumulate the required experience

    Complete roughly 4 years of qualifying experience before applying.

  3. 3

    Pass the Kentucky licensing exam

    Apply to test and pass the journeyman plumber exam, administered through KY Plumbing. Study the current Kentucky State Plumbing Code edition your state enforces.

  4. 4

    Apply, pay, and get licensed

    Submit your application to KY Division of Plumbing. Once licensed, you renew on a set cycle and complete continuing education to keep it active.

Get exam-ready

The Kentucky plumber exam trips up a lot of first-timers. Practice tests and study guides shorten the path.
