What is the IBEW aptitude test?

It is the aptitude test that many local Joint Apprenticeship and Training Committees (JATCs) of the IBEW and NECA use to select applicants for electrical apprenticeships. It measures two things, algebra and reading, and sits near the start of the application.

The test is administered by the local training center, not by an employer, and a typical path, as training centers and prep guides describe it, runs like this: you apply to your local JATC, sit the aptitude test, are interviewed if your score qualifies, and are then ranked for placement with a contractor. Locals differ in the order, the scoring weights and the paperwork, so treat this as a map, not a rulebook.

Many locals also list basic requirements, for example age, schooling and algebra coursework. Those are set locally; check your JATC's application page. This guide covers the test itself.

How many questions are on the IBEW aptitude test, and how long is it?

69 questions in two timed parts, as reported by prep sources: 33 algebra and functions questions in 46 minutes and 36 reading comprehension questions in 51 minutes, which is 97 minutes of testing. Calculators are not allowed.

What math is on the IBEW aptitude test?

Algebra and functions at about the level of a first high-school algebra course: solving equations and inequalities, exponents and polynomials, factoring quadratics, reading and building function rules from tables and graphs, and solving two equations at once.

Topics as reported by prep sources, with our fast method for each.
TopicWhat the question looks likeThe move that saves time
Order of operations and signed numbersBrackets, powers, then multiply and divide, then add and subtract; negatives squaredWrite each step on its own line; a squared negative needs brackets
Linear equationsOne unknown, brackets, unknowns on both sides, fractionsDo the same thing to both sides; check by substituting your answer
InequalitiesSolve like an equation, then give the rangeTurn the sign round when you multiply or divide by a negative
Exponents and polynomialsProduct and power rules, expanding and factoringSame base: add powers when multiplying, multiply them for a power of a power
QuadraticsFactoring to find the rootsTwo numbers that multiply to the constant and add to the middle number
Functions and tablesEvaluate f(x); find the rule from a table or two pointsChange in y for each step of x is the slope; the value at x = 0 is the constant
Systems of equationsTwo equations, two unknownsAdd or subtract the equations to remove one unknown
Formulas and word problemsRearranging electrical-style formulas; turning a sentence into an equationWrite what each letter stands for, substitute, then solve

Nine worked algebra examples

Each is original, shown with the method and the mistake that catches people. Cover the steps, solve it, then check your working against ours.

  1. IBEW-style question 1 · Linear equation · about 84 seconds on the real clock

    Solve for x: 3(x − 4) = 2x + 7

    1. Ax = −5
    2. Bx = −19
    3. Cx = 19
    4. Dx = 11
    Worked answer

    C: x = 19. Multiply out the bracket, then collect the x terms on one side.

    1. Multiply every term in the bracket by 3: 3x − 12 = 2x + 7.
    2. Subtract 2x from both sides: x − 12 = 7.
    3. Add 12 to both sides: x = 19.
    4. Check: 3(19 − 4) = 45 and 2 × 19 + 7 = 45.

    The trap: Multiplying the 3 into the x only, which gives 3x − 4 = 2x + 7 and x = 11.

  2. IBEW-style question 2 · Inequality · about 84 seconds on the real clock

    Solve: −2x + 7 > 13

    1. Ax < −3
    2. Bx > −3
    3. Cx < 3
    4. Dx > 3
    Worked answer

    A: x < −3. Solve it like an equation, but turn the sign round when you divide by a negative number.

    1. Subtract 7 from both sides: −2x > 6.
    2. Divide both sides by −2 and turn the sign round: x < −3.
    3. Check with x = −4, which should work: −2(−4) + 7 = 15, and 15 > 13.

    The trap: Dividing by −2 and leaving the sign as it was, which gives x > −3.

  3. IBEW-style question 3 · Quadratic · about 84 seconds on the real clock

    Solve: x² + 5x − 24 = 0

    1. Ax = 8 or x = −3
    2. Bx = −6 or x = 4
    3. Cx = 6 or x = −4
    4. Dx = −8 or x = 3
    Worked answer

    D: x = −8 or x = 3. Find two numbers that multiply to the constant and add to the middle number.

    1. Look for two numbers that multiply to −24 and add to 5: 8 and −3.
    2. So the equation factors as (x + 8)(x − 3) = 0.
    3. Each root has the opposite sign to the number in its bracket: x = −8 or x = 3.
    4. Check: (−8)² + 5(−8) − 24 = 64 − 40 − 24 = 0, and 3² + 15 − 24 = 0.

    The trap: Reading the roots straight off the brackets, which gives x = 8 or x = −3.

  4. IBEW-style question 4 · Absolute value · about 84 seconds on the real clock

    Solve: |2x − 3| = 9

    1. Ax = 9 or x = −9
    2. Bx = 6 or x = −3
    3. Cx = 6 or x = −6
    4. Dx = 3 or x = −6
    Worked answer

    B: x = 6 or x = −3. An absolute value equation has two cases: the inside equals 9, or it equals −9.

    1. Case 1: 2x − 3 = 9, so 2x = 12 and x = 6.
    2. Case 2: 2x − 3 = −9, so 2x = −6 and x = −3.
    3. Check: |2 × 6 − 3| = 9 and |2 × (−3) − 3| = |−9| = 9.

    The trap: Stopping after the first case. An absolute value question nearly always has two answers.

  5. IBEW-style question 5 · Function table · about 84 seconds on the real clock

    The table shows a linear function. What is f(10)?

    x1234
    f(x)581114
    1. A30
    2. B29
    3. C32
    4. D35
    Worked answer

    C: 32. A linear function adds the same amount for every step of x. Find that amount and the starting value.

    1. f(x) rises by 3 each time x rises by 1, so the rule starts f(x) = 3x + b.
    2. Use the first pair: 5 = 3 × 1 + b, so b = 2 and f(x) = 3x + 2.
    3. f(10) = 3 × 10 + 2 = 32.
    4. Check the rule against the last pair: 3 × 4 + 2 = 14.

    The trap: Using 5 as the constant (3x + 5 gives 35). The value at x = 1 is not the value at x = 0.

  6. IBEW-style question 6 · Slope and intercept · about 84 seconds on the real clock

    A line passes through (2, 5) and (6, 13). Which is its equation?

    1. Ay = 2x − 1
    2. By = 2x + 1
    3. Cy = 2x + 3
    4. Dy = x/2 + 4
    Worked answer

    B: y = 2x + 1. Find the slope as rise over run, then use one point to find the intercept.

    1. Slope = (13 − 5) ÷ (6 − 2) = 8 ÷ 4 = 2.
    2. Put the point (2, 5) into y = 2x + b: 5 = 4 + b, so b = 1.
    3. The line is y = 2x + 1. Check with (6, 13): 2 × 6 + 1 = 13.

    The trap: Turning the slope upside down (run over rise). The option y = x/2 + 4 passes through (2, 5) but not (6, 13).

  7. IBEW-style question 7 · Exponents · about 84 seconds on the real clock

    Simplify: (3x²)(2x³)

    1. A6x⁵
    2. B5x⁵
    3. C6x⁶
    4. D5x⁶
    Worked answer

    A: 6x⁵. Multiply the numbers; add the exponents of the same letter.

    1. Multiply the numbers in front: 3 × 2 = 6.
    2. Add the powers of x: x² × x³ = x²⁺³ = x⁵.
    3. The product is 6x⁵.

    The trap: Adding the numbers (5) or multiplying the powers (x⁶). Numbers multiply; powers add when you multiply, and multiply only when a power is raised to a power.

  8. IBEW-style question 8 · Formula · about 84 seconds on the real clock

    In the formula P = I²R, P = 450 and I = 5. What is R?

    1. A90
    2. B45
    3. C2250
    4. D18
    Worked answer

    D: 18. Put the numbers in, square first, then divide.

    1. Square the current: I² = 5 × 5 = 25.
    2. The formula is now 450 = 25 × R.
    3. Divide both sides by 25: R = 18.

    The trap: Dividing by I instead of I², which gives 90.

  9. IBEW-style question 9 · Two equations · about 84 seconds on the real clock

    Solve together: 2x + y = 11 x − y = 1

    1. Ax = 4, y = −3
    2. Bx = 4, y = 3
    3. Cx = 3, y = 5
    4. Dx = 5, y = 1
    Worked answer

    B: x = 4, y = 3. Add the two equations so that y disappears.

    1. Add the left sides and the right sides: 3x = 12, so x = 4.
    2. Put x = 4 in the second equation: 4 − y = 1, so y = 3.
    3. Check in the first: 2 × 4 + 3 = 11.

    The trap: Checking an answer in one equation only. x = 3, y = 5 fits the first equation (6 + 5 = 11) and fails the second (3 − 5 = −2).

What is on the reading comprehension section?

Short informational passages, each followed by multiple-choice questions that ask what the passage says, what it suggests and what a word means in context. You answer from the text alone, not from what you already know.

Question types as commonly described, with the wording pattern and our method.
Question typeHow it is usually wordedHow to answer it
DetailAccording to the passage, ...Find the sentence that states it. The right option restates that sentence in other words.
Main ideaWhich of these best states the main point of the passage?Ask what the passage as a whole is about. Wrong options are one detail, or a bigger claim than the passage makes.
InferenceThe passage suggests that ... / The author would most likely agree that ...Find what must be true given what is stated. The right option goes one small step beyond the text, never a leap.
Vocabulary in contextAs used in the passage, "x" most nearly means ...Put each option into the sentence in place of the word. The meaning the sentence needs wins, even if it is not the first meaning you think of.
Conclusion from evidenceWhich conclusion is best supported by the passage?Check each option against the text and keep the one with direct support. Real-world truth does not count.

A worked passage

An original passage in the style of the test, with two questions. Read the passage once, then answer before opening the working.

Passage: Marking Before Drilling

Before an electrician drills a single hole, the position of every box, run and panel is usually marked on the wall or floor from the drawings. This step looks slow, and new workers are often tempted to skip it and measure as they go. Experienced crews know better. A mark made once can be checked by a second person, shown to the other trades, and corrected for the price of a pencil line. A hole drilled in the wrong place can only be patched, and a box set at the wrong height may have to be moved after the wall has been finished. The few minutes spent marking are therefore not a delay but a form of insurance.

  1. IBEW-style question 10 · Detail

    According to the passage, why is a mark useful before drilling?

    1. AIt is required by the other trades on the site.
    2. BIt can be checked by someone else and corrected cheaply.
    3. CIt lets the crew leave the drawings in the truck.
    4. DIt makes drilling quicker than measuring as you go.
    Worked answer

    B: It can be checked by someone else and corrected cheaply.. The passage says a mark "can be checked by a second person, shown to the other trades, and corrected for the price of a pencil line."

    1. A detail question is answered by finding the sentence, not by remembering the gist. Find the sentence about marks being useful.
    2. It says a mark can be checked by a second person and corrected for the price of a pencil line.
    3. The option that restates it is the right one. The other options sound sensible but none is stated: nothing says the drawings are set aside, nothing says marking is quicker, and the other trades are only shown the marks, not said to require them.

    The trap: Picking an option that is probably true on a real job but is not in the passage.

  2. IBEW-style question 11 · Inference

    Which statement would the author most likely agree with?

    1. AExperienced crews rarely make mistakes.
    2. BDrawings cannot be trusted until they have been marked.
    3. CNew workers should not be allowed to measure.
    4. DTime spent on preparation can save more time later.
    Worked answer

    D: Time spent on preparation can save more time later.. The last sentence calls the minutes spent marking "a form of insurance", which means they protect against a bigger loss later.

    1. An inference question asks what the passage supports without saying it outright. Look for the author's conclusion; it is usually in the last sentence.
    2. The author calls the minutes spent marking "not a delay but a form of insurance": a small cost now that guards against a larger cost later.
    3. The correct option says the same thing in general terms. The options about experienced crews and about new workers go further than the passage (it never says experienced crews rarely err, or that new workers must not measure), and the option about the drawings says something the passage does not.

    The trap: Choosing an option that is too extreme: words like "rarely", "cannot" and "not be allowed" usually claim more than the passage does.

How is the IBEW aptitude test scored?

Your correct answers are converted to a stanine, a score from 1 to 9 that places you against a reference group. Each stanine covers a fixed share of that group, with the middle score, 5, covering the middle 20%.

The alliance reports whether you qualified, not an exact standing, and who is in its reference group is not published. So the table below is the standard stanine scale, a way to read the number, not a prediction of your odds.

The standard stanine scale.
StanineShare of the groupPosition on the scale
14%The lowest 4%
27%Above 4%, up to 11%
312%Above 11%, up to 23%
417%Above 23%, up to 40%
520%Above 40%, up to 60%
617%Above 60%, up to 77%
712%Above 77%, up to 89%
87%Above 89%, up to 96%
94%The top 4%

A stanine is relative, so you cannot work out your stanine from your own percent correct. This is also why our practice test reports percent correct for each part and a band, and never a stanine or a percentile.

What stanine do you need to qualify for an electrical apprenticeship?

There is no universal minimum. Each local JATC sets its own, and reported qualifying stanines run from 3 or 4 up to 5 and above: most prep sources quote 4, a few locals interview at 3, and the Central New York program publishes 5 or above.

Reported ranges, not guarantees. A qualifying score gets you to the interview; where you rank can depend on the score too.
Qualifying stanineWhat is reported
3Some locals are reported to interview at 3
4The figure most prep sources quote as the usual minimum
5 and abovePublished by the Central New York program (CNYETA) as its requirement; other locals may ask for it

Which cut-off applies to you?

  1. Does your JATC's apprenticeship page state a minimum stanine?

    Yes
    Use that figure. It overrides everything on this page.
    No
    Go to question 2.

  2. Does your application packet or the message booking your test state one?

    Yes
    Use that figure.
    No
    Go to question 3.

  3. Can you ask the training center directly?

    Yes
    Ask: "What stanine qualifies for the interview, and does the score also affect my ranking?" Write down the answer and the date.
    No
    Plan for a 5. It clears every cut-off reported here, including Central New York's.

Is this the same as the NJATC aptitude test and the electrician licensing exam?

The NJATC aptitude test is the older name for the same apprenticeship test. The electrician licensing exam is a different test, set by the state, that comes later and covers the electrical code.

Can you retake the IBEW aptitude test?

Usually yes, after a wait. A six-month wait after a non-qualifying score is commonly cited, but retake rules are set by the alliance and your JATC, so ask before you book.

The wait is the reason to prepare before the first attempt rather than after it. A 97-minute test you have never seen on a clock is the wrong way to find your weaker half. Sit a timed mock first, then spend your weeks on the part that cost you marks.

How should you prepare for the IBEW aptitude test?

Sit one full timed mock to find your weaker part, drill that part for a week or two, then sit another mock on the real clock. Do algebra without a calculator from day one, and practise reading by answering only from the passage.

The how-to-pass guide has the pacing checkpoints, fast methods for each algebra topic, a reading method with a worked trap, and one-week, two-week and four-week plans. For a quick check of your algebra first, the free IBEW-style test gives you a score for each part in about 97 minutes, or sit just the algebra part and stop.

Frequently asked questions

What is the IBEW aptitude test?

It is the entrance test for electrical apprenticeships run by local JATCs, the joint IBEW and NECA training committees. It has two timed multiple-choice parts: algebra and functions, then reading comprehension.

How many questions are on the IBEW aptitude test?

Prep sources report 69 in all: 33 algebra and functions questions in 46 minutes and 36 reading comprehension questions in 51 minutes. The format varies by JATC, so check yours.

What is a passing score on the IBEW aptitude test?

Each JATC sets its own qualifying stanine. Reported cut-offs run from 3 or 4 up to 5 and above; Central New York publishes 5 or above. Ask your training center what it needs and whether the score also affects your ranking.

Is the IBEW aptitude test hard?

The algebra is first-year high-school level and the reading is plain informational text. What makes it hard is the clock (about 84 seconds a question), the lack of a calculator and the fact that a stanine is relative to other applicants.

Can I retake the IBEW aptitude test?

Usually, after a wait. A six-month wait after a non-qualifying score is commonly cited, but local rules differ, so ask your training center before you test.

Does the IBEW aptitude test have a calculator?

Prep sources report no calculator. Scratch paper is provided.

Is there a free IBEW aptitude test practice?

Yes. Our IBEW-style practice test is free: 69 questions in the two timed parts, scored for each part, with no sign-up. It is not the official test, and we are not affiliated with the IBEW, NECA or the Electrical Training Alliance.
