IBEW aptitude test practice
The electrical apprenticeship aptitude test has two timed sections: algebra and functions, and reading comprehension. Practise the algebra half here, on the clock and without a calculator, with a fresh set every time. Then see what score gets you an interview.

What is on the IBEW aptitude test
Apprenticeships run jointly by the IBEW and NECA are filled through local Joint Apprenticeship and Training Committees (JATCs), and most of them use the aptitude test from the electrical training alliance. It is a multiple-choice test with no calculator, in two timed sections:
| Section | Questions and time (commonly reported) | What it covers |
|---|---|---|
| Algebra and functions | 33 questions, 46 minutes | Order of operations, linear and quadratic equations, polynomials, exponents, inequalities, reading functions from tables and graphs |
| Reading comprehension | 36 questions, 51 minutes | Stated details, main idea, inference, meaning from context, conclusions from evidence |
How it is scored: the stanine
Your result is a stanine, a score from 1 to 9 that places you against a reference group. Most sources say a stanine of 4 or more qualifies you for an interview; some locals interview at 3, and others ask for 5 (the Central New York program, for example, publishes 5 or above). The alliance tells you whether you qualified, not your exact standing.
Stanines are a standard scale: each band covers a fixed share of the reference group. So qualifying with a 4 means scoring above roughly the lowest quarter. That gets you to the interview; where you then rank on the list often depends on the score as well, so a 6 or 7 is worth chasing.
| Stanine | Share of the reference group | Roughly beats |
|---|---|---|
| 1 | 4% | nobody to 4% |
| 2 | 7% | 4% to 11% |
| 3 | 12% | 11% to 23% |
| 4 | 17% | 23% to 40% |
| 5 | 20% | 40% to 60% |
| 6 | 17% | 60% to 77% |
| 7 | 12% | 77% to 89% |
| 8 | 7% | 89% to 96% |
| 9 | 4% | the top 4% |
Worked examples: the four question types that cost the most
Each of these comes up in some form on the algebra section. Try it, then read the method.
Example 1 · Evaluate a function
If f(x) = 2x² − 1, what is f(−1)?
- A. 2
- B. 5
- C. −3
- D. 1
Example 2 · Function table
Which rule produces every pair in the table?
| x | 0 | 1 | 2 | 3 |
|---|---|---|---|---|
| y | 2 | 5 | 8 | 11 |
- A. y = 3x + 2
- B. y = 2x + 3
- C. y = 4x + 1
- D. y = 3x + 5
Example 3 · Two equations
Solve together: x + y = −3 4x − y = −17
- A. x = −4, y = 1
- B. x = 1, y = −4
- C. x = −3, y = 0
- D. x = 4, y = 1
Example 4 · Quadratic
Solve: x² − x − 12 = 0
- A. x = 3 or x = 4
- B. x = −3 or x = 4
- C. x = −4 or x = 3
- D. x = −4 or x = −3
Timing and the no-calculator rule
At 33 questions in 46 minutes you have about 84 seconds a question in algebra, and about 85 seconds in reading at 36 in 51. That is enough time to work carefully, not enough to get stuck. Without a calculator, the numbers are chosen to be friendly, so if your working produces an ugly decimal, check for a slip before you go on.
- Substitute the options back into the equation when solving looks slow: it is often faster and it cannot go wrong.
- For function tables, find the change in y per step of x (the slope) and the value at x = 0 (the constant). Check one more pair before you commit.
- For quadratics, look for two numbers that multiply to the constant and add to the middle coefficient. Each root has the opposite sign to the number in its bracket.
- Flip the inequality sign whenever you multiply or divide by a negative number.
Common mistakes
- Squaring a negative without brackets: (−3)² is 9, but −3² written carelessly becomes −9.
- Slope upside down: rise over run, change in y over change in x.
- Distributing to the first term only: 3(x − 4) is 3x − 12, not 3x − 4.
- Adding exponents when you should multiply them: (x³)² is x⁶; x³ · x² is x⁵.
- In reading, choosing an answer that is true in real life but not stated in the passage.
A study plan for the time you have
| Time to the test | Plan |
|---|---|
| 1 week | Day 1: a timed set above to find weak spots. Days 2 to 5: one topic a day (signed numbers and order of operations, linear equations, exponents and polynomials, functions and graphs) plus a set. Day 6: two sets back to back. Day 7: rest. |
| 2 weeks | Week 1 as above, plus 20 minutes of reading practice a day (passages with questions, answered from the text only). Week 2: two timed algebra sets a day and one full reading passage set. |
| 1 month | Rebuild the basics first: fractions, negatives, exponents, factoring. Then a set a day, and a full two-section simulation each weekend. |
