The Electrical Training Aptitude Test (ETAT) is a critical component of the application process for individuals seeking to enter electrical apprenticeship programs, particularly through the International Brotherhood of Electrical Workers (IBEW) and the National Electrical Contractors Association (NECA). The test is designed to measure a candidate’s basic academic skills and potential to succeed in technical training.
The ETAT consists of two primary sections: algebra and functions and reading comprehension. The algebra portion evaluates your ability to solve equations, work with variables, and interpret basic mathematical functions—skills essential for understanding electrical principles. The reading comprehension section tests your ability to understand and analyze written information, which is important for interpreting safety guidelines, technical documents, and codes.
This is a timed, multiple-choice exam, typically lasting about 2.5 hours. Candidates are not allowed to use calculators, so strong mental math and reading skills are crucial. Preparation is key to performing well. Many candidates use practice tests and study guides to build confidence and improve speed and accuracy.
Scoring well on the ETAT is essential for advancing to the interview stage of an apprenticeship program. A high score demonstrates readiness for the rigorous academic and hands-on training required to become a licensed electrician.

Here’s a free sample question that reflects the type of content you might encounter in an electrical aptitude test:
Question:
A circuit consists of a 12-volt battery connected to a resistor. The current flowing through the circuit is measured as 2 amperes. What is the value of the resistance in the circuit?
A) 6 ohms
B) 10 ohms
C) 14 ohms
D) 24 ohms
In this question, you are given the voltage (12 volts) and the current (2 amperes) in a circuit. To calculate the resistance, you can use Ohm’s law, which states that resistance (R) is equal to voltage (V) divided by current (I). So, to find the resistance (R), divide the given voltage (12 volts) by the current (2 amperes).
Solution:
Resistance (R) = Voltage (V) / Current (I)
Resistance (R) = 12 volts / 2 amperes
Resistance (R) = 6 ohms
Question
Which of the following is the SI unit of electrical resistance?
A) Ampere (A)
B) Volt (V)
C) Watt (W)
D) Ohm (Ω)
Question
If a circuit has a voltage of 24 volts and a resistance of 6 ohms, what is the current flowing through the circuit?
A) 2 amperes
