Pipefitters and HVAC service techs who come up through a United Association apprenticeship finish with a journeyman card, roughly 10,000 hours in the field, and no student debt. Locals get more applicants than they have slots, and the aptitude test is the first cut. Most people who wash out never make it past it.

Pipefitters, steamfitters, and HVAC/R fitters generally fall under the same UA trade classification and sit for the same exam. If you are applying to a plumbing apprenticeship instead, the test is also GAN-administered but the section breakdown is different. See our UA plumber aptitude test guide.

This guide breaks down all four sections of the test, what score puts you in contention, and where applicants most commonly lose ground. Wages vary by local and market. Check current rates in your state for pipefitters or HVAC technicians.

Testing procedures vary by local. Most use the GAN battery. Some do not. Call your local's training center and ask what you are actually sitting for before you spend money on prep.

75 is the passing threshold. Clearing it does not get you in. It gets your name on a ranked list, and locals work that list from the top. Most locals open enrollment once or twice a year, so the gap between a 75 and an 88 is often the gap between starting this year and starting next year.

The GAN pipefitter battery covers four sections: reading comprehension, math, mechanical ability, and figure visualization. No calculator, and the clock runs throughout.

The math section covers fractions, decimals, unit conversions, and measurement. Nothing past early high school. The difficulty is the format: no calculator and a running clock. Fitting work is full of fractional dimensions and offset calculations, and the test is checking whether you can handle that arithmetic without reaching for a phone. Applicants who have been out of school a while consistently underestimate how much speed they have lost.

The mechanical ability section tests applied physics. Gears, levers, pulleys, pressure, and how systems behave under load. It maps directly to the daily work of fitting and HVAC service, and applicants who have turned wrenches on cars or equipment tend to have an edge. Everyone else builds it through practice.

Figure visualization tests spatial reasoning. You will see flat patterns and have to determine what three-dimensional shape they fold into, plus questions about how objects relate in space. Applicants underestimate this section more than any other because nothing in school prepares you for it. It is also the section that maps most directly to reading isometric drawings and routing pipe through a structure.

Reading comprehension gives you dense technical passages and asks you to pull specific information out of them. The material is not complicated. The pacing is.

Content review is not the same as preparation. You can understand how to calculate a rolling offset and still run out of time on the test because you have never done it under a clock. The applicants who score well have already sat through the format before test day. JobTestPrep builds a package specifically for the UA fitter exam that mirrors the GAN structure across all four sections.

A passing score buys you an interview. The interview is also scored, and both numbers combine to set your position on the callup list. Applicants have tested well and still gone nowhere because they walked into the panel unprepared. The people across the table run the program and are gauging whether you will show up, stay, and finish. Be able to say why fitting specifically, what the work involves day to day, and how you plan to hold down full-time hours plus night classes for five years.

Application windows vary widely by local. Some accept applications year-round, others open a narrow window once or twice a year, and a few cap how many applications they distribute.Requirements are consistent across most of them: high school diploma or GED with transcripts, valid ID, and a passing drug screen before indenture. Some locals charge an application or testing fee. Veterans should ask about exam waivers, since some locals grant them with an honorable discharge. Have your documents assembled before the window opens, because incomplete applications get set aside and the next window may be a year out.
