Most ironworker locals test you twice: once on paper, once on your feet
- Free Mechanical-style test
- 55 questions, 25 minutes
- Score and weakest skill the moment you finish
No sign-up. Practice only, not the ironworker test itself.
Union ironworker apprenticeships are run by local joint apprenticeship committees, and each sets its own entry tests. Locals that publish their process describe a written aptitude test and, at several, an agility or physical test, with a drug test after selection.

How close is this practice test to the Ironworker apprentice test?
Prep sites describe ironworker aptitude tests as math, reading and mechanical reasoning, with pulley setups and gear questions in the mechanical part. Our mechanical practice test drills those principles with a drawing on each item, and our IBEW-style test adds no-calculator math and timed reading.
Locals choose their own tests and no union-wide format is published, so no practice test can match yours exactly. We do not cover spatial items beyond a few drawings, and nothing we offer prepares you for an agility or physical test.
It is a Mechanical-style test: 55 original questions in 25 minutes. Check the test name in your invitation email before you decide how to prepare.

Ironworker apprentice: the assessment at a glance
| Who sets the test | Each local's Joint Apprenticeship and Training Committee (JATC) |
| Written test | Reported to cover math, reading comprehension and mechanical reasoning, sometimes spatial items |
| Agility test | Run by locals such as Rockford's Local 498 alongside the aptitude test |
| Drug test | After selection and before enrollment at the New York locals 40 and 361, at the sponsor's expense |
| Length | A New York-focused prep source reports about two hours |
| Calculator | Prep guides say most tests do not allow one |
| Pass mark | Prep sites quote 70 percent, but we found no local publishing it |
The Ironworker apprentice stages, and who says so
Every stage is marked by its source. Stated means the body that sets or runs the test says it on its own pages. Candidates report means we found it only in candidate accounts and prep guides.
- 01
Recruitment and application
Stated by the test owner
A local announces a recruitment period; you apply through the local or its JATC with the documents it listsThe New York locals 40 and 361 recruitment, as reported by The Chief, required applicants to follow written directions as well as pass the test. - 02
Written aptitude test
About two hours at New York locals, a prep source reportsStated by the test owner
The ironworkers' written aptitude test, reported to cover math, reading and mechanical reasoningThe New York locals say applicants must pass it. The content and timing come from prep sites, not from a local. - 03
Agility or physical test
Stated by the test owner
A practical test of the physical demands of the work, where the local uses oneLocal 498 describes an agility and aptitude test. Prep sites report a physical agility part at Local 580 too. - 04
Selection, drug test and enrollment
Stated by the test owner
Ranking or interview by the JATC, then a drug test before you start the apprenticeshipAt the New York locals the drug test comes after selection and the sponsor pays for it.
Your local writes the rules
There is no single national ironworker entrance exam that every applicant takes. Each local's JATC runs its own recruitment, and a prep site notes that not every local requires an aptitude test at all, though the largest ones in New York City do.
So your first job is research, not practice. Find your local's recruitment notice and note four things: the test date, whether there is an agility test, what documents you must bring, and whether the local recommends any study material. Everything else on this page is a general picture to fill in with those details.
What the written test is reported to cover
Prep sites describe three core areas. Math covers fractions, decimals, geometry and basic algebra. Reading questions check whether you can follow instructions and safety procedures. Mechanical items ask about pulley setups and how gears interact, and some versions add spatial questions.
Ironworkers rig and raise steel, so pulleys and loads are the heart of the mechanical part. Our mechanical aptitude test covers pulleys, levers and gears with a drawing on nearly every item. For math by hand, the algebra section of our IBEW aptitude test is a useful proxy.
Following written directions is part of the test
The New York locals 40 and 361 list an unusual requirement next to the test: applicants must be able to follow written directions. On the job, a misread instruction at height is dangerous, and selection reflects that.
Practise reading the instruction before each set of questions, and answer exactly what is asked. In the application itself, fill every box, sign where asked and bring each listed document. A missing paper can end an application before the test ever matters.
Train for the agility test separately
Locals such as Rockford's Local 498 pair the written test with an agility test, and a prep site describes Local 580's physical assessment as designed to simulate the demands of the job. The exact events differ by local and are not always published in advance.
Ask the local what the agility test involves as soon as you apply, and train for it in parallel with your written prep. Carrying, climbing and working with your hands are the obvious themes; build general strength and grip, and do not let the written test take all your preparation time.
Plan for paper and no calculator
Prep guides say most ironworker tests do not allow a calculator, and a New York-focused source describes a proctored, multiple-choice session of about two hours. Fractions and decimals are where hand arithmetic slows most people down.
Do timed sets of fraction addition, conversions between fractions and decimals, and area and perimeter problems, all by hand. Our mechanical test guide explains the pulley and lever rules, so you can spend your practice time on speed.

Tips for the Ironworker apprentice assessment
- 01
Start with your local's notice
It tells you whether there is a written test, an agility test or both. - 02
Practise pulleys first
Rigging questions sit at the center of the mechanical part prep sites describe. - 03
Do fractions by hand daily
Most tests are reported to ban calculators, and fractions are where time goes. - 04
Read every instruction twice
The New York locals list following written directions as a requirement in its own right. - 05
Train for agility in parallel
Physical tests are scored separately and can end an application on their own. - 06
Bring every document listed
An incomplete application can stop you before the test.
What candidates and prep sites report
These come from anonymous reviews, university careers pages and prep guides. They often disagree, and Ironworker apprentice has not confirmed them. Read them as leads, not rules.
- Prep sites report that the largest locals, including Local 40 and Local 46L in New York City, require the aptitude test.
- A prep guide says Local 580 test-takers may see fractions, decimals, geometry and basic algebra.
- Prep sites quote a 70 percent pass mark, but none of them names a local that publishes it.

Sources
Checked November 2026 through search summaries of a newspaper report on a New York recruitment, one local's apprentice page and prep sites; we did not read them in full. No local we found publishes its test content, timing or pass mark, so those details come from prep sites and could not be verified, and the union does not publish a national format.
