What is the Pipefitter / Steamfitter Union Apprenticeship Test ?
The pipefitter union apprenticeship test is a pre-apprenticeship aptitude exam required by United Association (UA) local unions for candidates applying to a pipefitter or steamfitter apprenticeship program. The test is administered by GAN Human Resources and is standardized across participating UA locals in the United States and Canada. It assesses four cognitive skill areas: reading comprehension, mathematical reasoning, mechanical aptitude, and spatial reasoning. The exam contains multiple-choice questions and candidates must score a minimum of 75% to pass. The test does not assess trade knowledge or hands-on pipefitting skills - it measures the cognitive aptitude needed to succeed in a five-year apprenticeship program that combines on-the-job training with classroom instruction. Candidates who pass the written test typically proceed to an interview with their local JATC (Joint Apprenticeship and Training Committee) before being accepted into the program.

Question 1 - Mechanical Reasoning (Cogwheels)
A system of cogwheels is shown in the diagram below:
An external force turns the cogwheel on the extreme left in the given direction (counter clockwise). Which cogwheel will turn faster, the first one (I) or the second one (II)?
The correct answer is (B) - Cogwheel 2.
The ratio of angular velocity is inversely proportional to the gear ratio (the bigger the driver cogwheel compared to the driven cogwheel, the faster the driven cogwheel will turn).
Therefore, we can understand that since the number of teeth of cogwheel 2 is smaller than cogwheel 1, its velocity is greater.
Question 2 - Reading Comprehension
“Sharing economy” is on the rise, with millions of people renting beds, cars, boats and other assets directly from each other, coordinating the transaction via the internet. Technology has reduced transaction costs, making sharing assets cheaper and easier than ever, and therefore possible on a much larger scale. The big change is the availability of more data about people and things, which allows physical assets to be disaggregated and consumed as services. Smartphones with GPS let people see where the nearest rentable car is parked; social networks provide a way to check up on people and acquire additional information; and online payment systems handle the billing.
Which one of the following probably contributed the most to the rise of “sharing economy”?
Question 3 - Spatial Reasoning
The letters near the sides of each shape point out where exactly should the different shapes be joined together. Which of the following options shows the joint shape?
Question 4 - Mechanical Reasoning (Hydraulics)
How long will it take to fill the pool, using a pipe with a flow rate of 1 [liter/second]?
Question 5 - Trades Math Algebra
What is the value of X?
If none of the options is the correct answer, please choose answer choice (E), "N."
8/X - 0.16 = 0.64 X =?
Question 6 - Math Word Problem

How Did You Do?
You just worked through questions covering Reading Comprehension, Mathematical Reasoning, Mechanical Aptitude, and Spatial Reasoning - the four sections of the real pipefitter and steamfitter union aptitude test.
Some sections probably felt straightforward. Others may have exposed gaps you did not expect - a calculation that slowed you down, a mechanical concept you recognized but could not pin down under pressure.
The results of this test are used to make real apprenticeship placement decisions. The questions you just saw are a small sample. The actual test is longer and moves faster.The candidates who pass are not necessarily the most experienced - they are the ones who prepared specifically for the UA exam format and question style.
JobTestPrep's Pipefitter PrepPack gives you 850+ practice questions, full section simulations, and detailed answer explanations - so you walk into test day knowing exactly what to expect.
Pipefitter Aptitude Test FAQs
Pipefitters and steamfitters are closely related trades that fall under the same union - the United Association of Journeymen and Apprentices of the Plumbing and Pipefitting Industry (UA). The key distinction is in the systems each trade works on-
- Pipefitters install, maintain, and repair piping systems that carry water, chemicals, gases, and process fluids in industrial and commercial settings.
- Steamfitters specialize specifically in high-pressure steam and hot water systems, typically in power plants, refineries, and large mechanical facilities.
In practice, many locals use the terms interchangeably, and in most UA jurisdictions pipefitters and steamfitters hold the same license and work under the same collective bargaining agreement. Both trades enter through the same apprenticeship pathway and take the same pre-apprenticeship aptitude test administered by GAN Human Resources. The test covers reading comprehension, mathematical reasoning, mechanical aptitude, and spatial reasoning - regardless of whether you are applying as a pipefitter or a steamfitter. You can find your local UA hall and apprenticeship application information at ua.org.
The Piping Industry Entry Level Assessment is another name used for the pre-apprenticeship aptitude test required by UA local unions for pipefitter and steamfitter apprenticeship applicants. It is the same exam administered by GAN Human Resources under various names across different locals - you may also see it referred to as the pipefitter aptitude test, pipefitter assessment test, or UA entry exam.
A static PDF can show you what types of questions appear on the pipefitter aptitude test, but it cannot replicate the conditions that determine whether you pass. The GAN Human Resources pipefitter exam is timed - and time pressure is where most unprepared candidates lose points, not on the question content itself. A PDF does not track your time per question, does not adapt to where your gaps are, does not explain why a wrong answer is wrong, and does not simulate the experience of working through a full section under exam conditions. Our Pipefitter PrepPack includes 850+ practice questions with full timed simulations across all four test sections, detailed answer explanations written by test preparation experts, and section-level score analysis so you know exactly where to focus before test day. Candidates who prepare with timed, scored practice consistently outperform those who review static question lists - because the real test rewards speed and accuracy together, not just familiarity with the content.
N - and that distinction matters. This test covers the pre-apprenticeship aptitude exam you take before entering a pipefitter apprenticeship program, not the in-program assessments completed during your first year as a registered apprentice. . First year in-program exams test actual trade knowledge - pipe sizing, fittings, blueprints, safety. Those are different assessments entirely.
The pipefitter helper test typically refers to an entry-level assessment used by some employers and non-union contractors to screen candidates for pipefitter helper or pipefitter assistant positions. A pipefitter helper is an entry-level role where workers assist journeyman pipefitters on job sites - carrying materials, preparing work areas, and learning the trade before formally entering an apprenticeship. The helper test varies by employer but generally covers basic math, mechanical reasoning, and reading comprehension - the same core skill areas practiced on this page.
The mathematical reasoning section of the pipefitter aptitude test covers arithmetic, fractions, decimals, percentages, basic algebra, and applied word problems. Questions are designed to reflect the type of calculation work pipefitters perform on the job - unit conversions, measurements, and formula applications - but tested at a cognitive aptitude level rather than as trade knowledge.
Calculator policy varies by local and test administration. We recommend checking directly with your local UA JATC or contacting GAN Human Resources at ganhumanresources.com to confirm the rules for your specific test date. Regardless of whether a calculator is permitted, practicing under timed conditions without one is strongly recommended - fractions, percentages, and unit conversions need to be fast and accurate, and relying on a calculator for mental arithmetic slows most candidates down under test pressure.

I would fully recommend
I picked the pipefitter one to study you have a lot of electrical questions. which doesn't go with pipefitter. i would still recommend it to others a lot of info.
Got the test prep pack for the EIAT and I passed!
Good to help study
