IBEW Aptitude Test: What's on the Electrical Apprenticeship Test and How to Prepare

The IBEW aptitude test is the electrical apprenticeship aptitude test that many IBEW and NECA training programs (JATCs) use to decide who gets an interview. The standard version has two multiple-choice sections: Algebra and Functions (33 questions in 46 minutes) and Reading Comprehension (36 questions in 51 minutes). No calculator is allowed, and you don't need any electrical knowledge.

Rules differ by program. Minimum scores, retest waits, fees and even the test itself can change from one local JATC to the next, so confirm the details with yours.

The test is only the first gate. Our Electrician Course doesn't include aptitude test prep, but it covers what comes next: the interview and your first days on a job site.

Key takeaways

• Two sections: Algebra and Functions (33 questions, 46 minutes) and Reading Comprehension (36 questions, 51 minutes). No calculator.
• There's no penalty for guessing, so answer every question.
• Rules vary. One JATC we checked wants a 4 or higher on a 1 to 9 scale, another wants a 5. Retest waits we found were 3 or 6 months.
• Passing gets you an oral interview. Under the ALLIANCE's rules, the interview and your qualifications set your rank on a two-year eligibility list.
• Practice by hand under a timer. The free Career Potential Test (CPT) can show your weak areas, but it isn't the IBEW test and doesn't replace it.

What Is the IBEW Aptitude Test?

It's a two-part math and reading test from the electrical training ALLIANCE, which serves the IBEW (International Brotherhood of Electrical Workers) and NECA (National Electrical Contractors Association). Your local JATC (joint apprenticeship and training committee) schedules it and gets your results. You need a qualifying score to get an interview.

The ALLIANCE's applicant page calls it the "NJATC aptitude test battery" and says, "Previous knowledge of electrical work is not required." It checks math and reading, not trade skills.

The ALLIANCE says local requirements may include a minimum age, a high school diploma or GED, and a full year of high school algebra with a passing grade. Other rules vary by program.

Not every JATC uses the same test

Minnesota's Department of Labor and Industry notes that applications to the Minneapolis Electrical JATC "include a GAN Aptitude Test." If your local names a different test, study for that one.

What's on the Electrical Apprenticeship Aptitude Test

The standard electrical apprenticeship aptitude test has two sections, algebra and functions first, then reading comprehension, with a short break in between. Each question has one correct answer.

Algebra and Functions: 33 questions in 46 minutes

Expect first-year high school algebra, done by hand, at a little under a minute and a half per question. The official sample questions include these types, in our words:

• Plugging numbers into a formula.
• Multiplying out expressions with parentheses and simplifying.
• Finding the rule in a number series.
• Deciding when an expression comes out positive or negative.
• Matching a table of inputs and outputs to the formula behind it.

Reading Comprehension: 36 questions in 51 minutes

You read short nonfiction passages and answer questions about them. The official sample uses a history passage, with questions on specific details, what you can infer, and which statement matches the passage.

How the IBEW Aptitude Test Is Timed and Scored

Plan on about three hours at the test center. Your score is based only on how many questions you get right, and you'll usually learn whether you qualified, not your exact score.

Here's what the ALLIANCE's applicant page says:

• The test takes about two and a half hours, with a short break between sections.
• Bring a photo ID. Pencils and all other materials are provided, and you can't use a calculator.
• There's no penalty for guessing.
• Your JATC gets results in about two to four weeks. You learn whether you qualified, but "exact scores are not provided."
• You must wait three months (90 days) to retest. Trying to get around that "may result in permanent disqualification."

How the rules vary by program

Do Non-Union Electrical Apprenticeships Use an Aptitude Test?

Some do and some don't. Programs outside the IBEW and NECA JATC system set their own rules, and some have no test at all because you join after an employer hires you.

Minnesota's state list shows the range. At Associated Builders and Contractors (ABC) of Minnesota and North Dakota, "there are no application fees or aptitude tests." Applicants join "after they are hired by a participating employer." Design Electric, an electrical company with its own program on the list, doesn't require an aptitude test either.

Applying to an ABC or IEC chapter somewhere else? Ask how they screen applicants. The same math and reading skills help either way.

How to Prepare for the IBEW Aptitude Test: A 6-Week Plan

Give yourself about six weeks. Get a baseline, rebuild your algebra by hand, sharpen your reading, then practice at real test pace.

1. Week 1: Check the rules and get a baseline. Confirm which test your JATC uses, the fee, the date and the retest wait. Need a testing accommodation? Tell your JATC as soon as you're scheduled. Then do the official sample questions with a timer and no calculator. Then take the free Career Potential Test for a timed baseline in math and reading.
2. Weeks 2 and 3: Rebuild your algebra. NIETC calls Khan Academy's free algebra class "good for algebra review." Focus on the sample question types, plus fractions, decimals and exponents. Do every problem on paper.
3. Week 4: Build reading speed. Read a nonfiction article daily and sum it up in one sentence. On practice questions, point to the line that proves your answer.
4. Week 5: Practice at test pace. Do timed sets at about 1.4 minutes per question. Practice skipping a hard one, guessing and moving on.
5. Week 6: Fix mistakes and rest. Redo every missed problem until you can explain it. Keep the last two days light, and confirm your test time, place and ID.

NIETC also notes that the ALLIANCE "hosts a website at ElectricPrep.com" to help applicants prepare their application.

Where the Career Potential Test Fits

The Career Potential Test (CPT) is not the IBEW aptitude test, and it isn't accepted in its place. It's free, timed, webcam-proctored practice that overlaps on math and reading, and its section breakdown can point to weak spots before the real thing.

We built the CPT, so we're not neutral, but here's an honest comparison.

Take it in week 1, check your math and reading results, then study and retake it in week 5. Your most recent score is the one shown, so retake after you've studied. Here's how the Career Potential Test works, and whether aptitude tests can predict job performance in general.

IBEW Aptitude Test Day Tips

Arrive early with a photo ID, answer every question and keep moving. The ALLIANCE's advice: "work steadily and carefully."

• Plan for about three hours. Leave the calculator at home. Pencils and other materials are provided.
• Answer everything. With no guessing penalty, a blank is a sure miss.
• Don't get stuck. The ALLIANCE says not to spend too much time on any one question.
• Prove reading answers. Check the passage instead of answering from memory.

What Happens After You Pass the Aptitude Test

A qualifying score gets you an oral interview with IBEW and NECA representatives. After that, you're ranked on an eligibility list.

The ALLIANCE says you get "an overall ranking" based on the interview and your qualifications. Your name then goes "on an eligibility list for two (2) years." NIETC, which works with IBEW Local 48, describes its interview this way:

• It's about a month after the test: ten minutes in front of a panel of 4 to 10 people, with four or five questions and a review of your transcripts and portfolio.
• The panel looks at character and attitude (including "knowledge of the industry"), work experience, and education and training (including "pre-apprenticeship or trade classes").
• "Your interview score determines your placement on the ranked list of eligible candidates."

A higher test score can still help. DuPage County's JATC may interview only its top aptitude scorers, "equaling 500% of the anticipated positions available."

For the rest of the hiring picture, read what it takes to get hired as an electrical apprentice or compare trade school, apprenticeship and online prep. Still deciding? Start with how to start an electrician career.

Where our Electrician Course fits

Our Electrician Course doesn't teach aptitude test prep. It helps you show up to the interview and your first day prepared. The self-paced course covers job-site safety (including lockout/tagout and arc-flash protection), electrical theory and Ohm's Law, the National Electrical Code (NEC), conduit bending, tools, wiring basics and blueprints. It ends with an interview and job search section covering common interview questions, with affordable add-on coaching for role-play practice.

Your instructor, Stephen Madrosen, started as an apprentice electrician with IBEW Local 48 in 2017. Whether a JATC gives interview credit for an online course is up to each program, so ask yours.

Our recommendation: Start with the official sample questions and the free Career Potential Test to find your weak spots. Study for six weeks, by hand and under a timer. Then, while you wait for your interview, try the free intro to our Electrician Course. The full course is $499 or four payments of $150, with a refund or course switch within 14 days if you haven't taken the final exam.

Frequently Asked Questions

Is the IBEW aptitude test hard?
The content is first-year high school algebra and reading. The hard parts are the pace, about 1.4 minutes per question, and doing math without a calculator. Timed practice on paper is the best fix.

Can you use a calculator on the IBEW aptitude test?
No. The electrical training ALLIANCE says you won't be able to use a calculator. Pencils and all other materials are provided.

What score do you need to pass the IBEW aptitude test?
It depends on the program. DuPage County Electrical JATC requires a 4 or higher on a 1 to 9 scale. Puget Sound Electrical JATC requires a 5 or higher for inside wireman. Under the ALLIANCE's standard rules, you only learn whether you qualified.

How soon can you retake the electrical apprenticeship aptitude test?
The ALLIANCE's rule is three months (90 days). Some programs wait longer. Puget Sound Electrical JATC sets six months, so check with your JATC.

Do you need electrical experience to take the IBEW aptitude test?
No. The ALLIANCE says previous knowledge of electrical work isn't required. Work experience can still help at the interview, since some panels score it.

Does the Career Potential Test count as the IBEW aptitude test?
No. The CPT is a separate test that we make, and it isn't accepted in place of a JATC's aptitude test. It's free, timed practice for the math and reading skills the two tests share.
