Plumber Exam Pass Rates by State (2026)
No states in our dataset publish an official Plumber first-attempt pass rate — every state is marked "not published".
Installs and repairs water, gas and drainage systems. Journeyman plumber licenses vary by state and locality; many require apprenticeship hours plus an exam. Rows without a figure are marked “not published” — we do not estimate rates that states have not released.

Frequently asked questions
Which states have the highest Plumber exam pass rate?
No states publish an official Plumber first-attempt pass rate in the dataset we retrieved on 2026-08-20.
Why is the Plumber pass rate "not published" for my state?
Most states do not release first-attempt exam pass rates. When a state publishes the figure, we show it with the source; otherwise the row is marked "not published" and you should ask the state board directly.
How hard is the Plumber exam overall?
Pass rates vary widely by state and are not consistently published. Focus on the highest-weighted content areas of your state's exam.
Does a low pass rate mean I will fail?
No. Published pass rates are first-attempt averages across all candidates, including those who take the exam without structured prep. Candidates who complete a study plan and practice questions pass at far higher rates than the aggregate figure suggests.
Compare Plumber data
Pass-rate figures are as published by state boards and commissions (retrieved 2026-08-20). “Not published” means the state has not released an official first-attempt figure — not that the rate is unknown to the board. Verify with your state board before making decisions.
