IBEW Aptitude Test: What's on It + Free 4-Week Plan
By the Zero to Journeyman research desk — every claim sourced below
The best-paid route into electrical work — a union apprenticeship — starts with a test most people hear about a week before they sit it. It's formally the Electrical Training Alliance Aptitude Test (Test 160), given by IBEW/NECA training centers (JATCs). Here's what's actually on it.
What it covers
Two sections, multiple choice:
- Algebra & functions — solving equations, number sequences, functions and graphs. This is the section that fails people. It's roughly first-year high school algebra, but most applicants haven't touched algebra in years.
- Reading comprehension — passages followed by questions about what they said and implied. Straightforward if you read regularly; rusty if you don't.
No trade knowledge is tested. You don't need to know what a conduit bender is — they're testing whether you can learn the classroom half of the apprenticeship.
How scoring works
You get a qualifying score — at most locals, a 4 on the 1–9 scale — and that earns you an interview. At the JATCs that publish their procedure, the score's job ends there: some don't even disclose your exact number, only whether you qualified, and your place on the list comes from the interview and a review of your qualifications. How the interview is scored, and the two things that let you re-interview for a better rank, is its own post. The test can typically be retaken after a waiting period (commonly 90 days) if it doesn't go your way — check with your local JATC.
The 4-week prep plan (free)
- Weeks 1–2: algebra rehab. Khan Academy's Algebra 1 course, one hour a day. Focus: linear equations, sequences, and function notation. This alone moves most people from fail to pass.
- Week 3: reading reps. Read something dense daily and summarize it in two sentences. News articles work; manuals work better.
- Week 4: timed practice. Full practice sets under time pressure. The format stress is real — rehearse it away.
That's it. No $200 course required. (If you want structured practice tests, they exist — but do the free algebra work first; it's where the points are.)
After you pass
Ranked interview → apprenticeship offer → you're earning from day one with zero tuition debt, on a path that runs to a journeyman license and, if you want it, $94k+ median data center work. The full route for your state — hours, exam, pay at every rung, sourced to the licensing board — is in our roadmaps:
- Electrician · Virginia (IBEW Local 26 / 666 entry points)
- Electrician · Texas (Locals 20, 520, 60, 716)
