Electrician Apprenticeship Exam Application Requirements

The test which is administered via NECA-IBEW Apprenticeship, has a number of requirements, which are important to bear in mind:

  1. The minimum age to take the test is 18.
  2. High school algebra course with a passing grade.
  3. Either high school diploma, GED or Associate Degree of minimum two years. The above requirements may be waved in the event that the applicant has enough documented work experience.

Electrician Apprenticeship Assessment Test Detail Overview

Let’s take a brief look into the content of the exams various segments.

Math Segment

  • What’s Included: This segment will include math questions on basic mechanical theory, pullies, and balance of loads which have been hoisted into the air.
  • Time and Questions: 33 questions in 46 minutes.

Reading Comprehension Segment:

  • What’s Included: You will be presented a number of written passages followed by questions from which you have to dissect and draw the right conclusions.
  • Time and Questions: 36 questions in 51 minutes.

Electrician Assessment Test Rules

It is important to follow nto rules below; otherewise - you can get disqualified from the test.

  1. Use of calculators
  2. Arriving less than 15 minutes prior to test time
  3. Failing to present an State or Federal ID
  4. Trying to re-take the test before the end of the mandated 6 month waiting time.

Sample Questions with Explanations

A light bulb with the following information is given: 10V, 4W.

Mechanical Reasoning - Electricity

What is the resistance (Ohm) of the light bulb? (in ohms):




The correct answer is 1.

In order to calculate the resistance we will use the following formulas:

$$V=R \times I$$
$$P=V \times I$$


R = Resistance [Ohm]

I = Current [A]

V = Voltage [Volt]

P = Power [Watt]

We will isolate R using the formulas above:
$$I = \frac{P}{V}$$
$$R = \frac{V}{\frac{P}{V}} = \frac{V^2}{P} = \frac{10^2}{4} = 25\ Ohm$$

Please note, if your answer was incorrect it is it possible that you used the equation incorrectly. Some of the distracters are counting on these mistakes, for example: R=I/V will lead you to option 3 (not resistance and therefore not in ohm units). In a similar way, R=I*V will lead to option 2 (also, not resistance and not in ohm units).

Mechanical Reasoning - cogwheels

The diagram shows two fixed cogwheels which can only rotate around their own axis. The red cogwheel has 24 teeth and the grey cogwheel has 12 teeth.

A toothed belt is inserted between the two cogwheels and is moved in the direction shown by the arrow.

In which direction and velocity of revolution will the grey cogwheel rotate in comparison to the red cogwheel? 



When contact is made between the toothed belt and the cogwheels a conversion from a linear velocity to an angular velocity occurs. Thus, the location of the point of contact is critical.

We can see from the diagram that the point of contact between the red cogwheel and the toothed belt is at the lower part of the red cogwheel, a position in which the linear velocity induces an angular velocity in a clockwise direction.

In contrast, the point of contact between the grey cogwheel and the toothed belt is at the upper part of the grey cogwheel, a position in which the linear velocity induces an angular velocity in a counter clockwise direction. It follows that the cogwheels rotate in opposite directions.

The angular velocity can be calculated using the thumb rule: "fewer teeth, faster velocity". Due to the inversely proportional ratio between the number of teeth and the velocity we are able to assume that since the grey cogwheel has half the number of teeth, its velocity must be double the velocity of the red cogwheel.

Understanding Your Trade Apprenticeship Test Score

The minimum score to even be considered for an interview (we will talk about that below) is a scoring of 4. The score will be from 1-9.

Electrician Apprenticeship Overview

What will an electrician apprenticeship look like? Here is an approximation of topics covered and the divide between classroom and real-work experience:

  • Classroom – Classes will include 575-1,000 hours, but this can vary according to the field.
  • Field training – On site training should fall between 8,000 to 10,000 hours.

Course topics according to various fields

  • Inside Wiremen – To be a inside wireman you will need first pass 5 years worth of courses, including 83 specific knowledge areas. From Splicing High Voltage Cables to identifying hazardous material, or Reading a Wire Tables, this in-classroom courses will give you everything you need to know to do the job right.
  • Outside Lineman – These series of courses will include 77 areas of expertise, covering a wide range of theory and practical training. You will learn how to use blueprints and know how to read its symbols , operate a bucket truck, gain comprehensive understanding of delta, and wye transformer connections, learn emergency rescue, and much more.
  • Residential Wiremen – For this position you will need to know all about Terminating Coaxial Cables, Aluminum or Copper Cables, and Twisted Pair Cables along with the other 85 areas of expertise related to the field. Moreover, the courses will arm you will all relevant safety rules and guidelines to keep you safe during your work.
  • Sound and Communication Technicians – The comprehensive sequence of courses will equip you well for the job. This will include, Structured Wiring, Basics of Telephony, understanding of LAN, Principles of Grounding, , Video, Voice, and Data Systems among 124 other areas expertise needed to excel in the field.

Panel Interview

The panel interview will include a mix of 4-10 interviews from the Training Center, and the National Electrical Contractors Association. It should be noted that aside from testing your knowledge the interview will also include a series of Behavioral Interview Questions. These question are designed to bring to light how you past experiences will affect performance, communication and output while on the job.
