PipePrep AI — built for the UA pipe trades battery
Union plumbing apprenticeships run through a UA local, and every applicant sits the same aptitude battery — a different test from the IBEW one this site is built around.
Straight up: I’m an IBEW journeyman electrician and a pre-apprenticeship instructor — not a UA member. What I know cold is how union selection works, and that part is the same across the building trades. The test content is not, which is why it’s a separate app.

What is the plumber apprenticeship aptitude test?
The plumber and pipefitter (UA) apprenticeship aptitude test is a standardized entrance exam used to screen and rank applicants for union apprenticeship programs. It typically covers numerical computation, numerical reasoning, reading comprehension, and mechanical comprehension. Scores are combined with an interview to rank candidates.
What score do you need to pass?
Most UA locals look for a combined score around 70% or higher to be competitive. Passing the minimum gets you on the list; a higher score moves you up it. The math sections — fractions, ratios, and basic algebra — carry significant weight.
How should you prepare?
Focus on fractions, measurement math, and ratios first, since they appear throughout the test. Practice timed questions so the pace feels familiar. Use this free practice test to find your weakest section, then drill it.
