Becoming an electrician apprentice is an exciting career path that requires dedication, knowledge, and skills in the electrical trade. As part of the apprenticeship journey, aspiring job seekers must undergo an electrician test to demonstrate their understanding of electrical concepts, codes, and practical skills. This standardized test assesses pre-employment candidates for the electrical hiring process in the United States and Canada.

The electrician test is given by the National Joint Apprenticeship and Training Committee (NJATC) as an assessment tool to evaluate the knowledge, aptitude, and skills of individuals seeking to become electrician apprentices. This test is essential in every electrical recruitment process to screen the candidates. The score is graded over nine; therefore, a candidate with a score of 4 is considered average. However, to get the most out of it, it is advisable to score seven and above.

What are the Sections in an Electrician Apprentice Test

Psychometrics are employed in this test, and it is divided into two sections:

• Algebra and functions
• Reading comprehension

• Algebra and Functions

This test evaluates your skills in algebra and related mathematical functions, measuring your ability to employ numerical reasoning and concepts. To successfully solve the questions, you should possess fundamental math knowledge, encompassing operations, exponents, roots, and approaches to fraction and decimal problems. Familiarity with elementary algebra, including writing, interpreting, and solving expressions such as linear and quadratic equations, is also essential.

• Reading Comprehension

This test section measures the candidate’s ability to read and understand technical material. The questions in this test section are typically passages that describe electrical concepts or procedures. The candidate is then asked to answer questions about the passage that requires them to demonstrate their understanding of the material. For example, the passage might describe the different types of electrical safety hazards or electrical tools. The question might then asks the candidate to identify the safety hazard that is associated with working on live electrical wires or the tools that are used to strip insulation from electrical cables.

Which types of Questions to Expect?

The electrician test typically covers various topics relevant to the electrical trade. These may include:

• Electrical Theory and Concepts

This section assesses candidates’ understanding of electrical principles, circuitry, Ohm’s law, voltage, current, resistance, power calculations, and electrical formulas. Candidates may be required to solve theoretical problems and answer questions related to electrical theory.

• National Electrical Code (NEC)

Knowledge of the NEC is crucial for electricians, as it outlines the safety standards and guidelines for electrical installations. The test may include questions on code requirements, grounding and bonding, conductor sizing, circuit protection, and wiring methods.

• Electrical Systems and Components

Candidates are tested on their knowledge of electrical systems, such as residential, commercial, and industrial installations. This section may cover electrical panels, wiring diagrams, circuit breakers, switches, outlets, transformers, motors, and lighting systems.

• Electrical Safety

Safety is of utmost importance in the electrical trade. The test may include questions on electrical hazards, lockout/tagout procedures, personal protective equipment (PPE), arc flash, and safe work practices. A candidate can answer this question whether they are a graduate or not.

• Tools and Equipment

Candidates may be assessed on their familiarity with standard electrical tools, equipment, and proper usage. This includes hand tools, power tools, meters, testers, conduit bending techniques, and wire termination methods.

Sample questions Electrician Apprentice Test

The questions listed below are examples of electric-related questions that might come out in your tests.

• A light bulb is rated at 60 watts. How much current does it draw when connected to a 120-volt circuit?
• A circuit breaker is rated at 20 amps. What is the maximum voltage that can be applied to the circuit breaker without it tripping?
• A resistor is connected to a 12-volt battery. If the resistor has a resistance of 6 ohms, how much current flows through the resistor?
• A circuit has a resistance of 10 ohms and a current of 5 amps. What is the voltage across the circuit?

How to Prepare for Electrician Apprentice Test

Preparation for the test is essential if you aim to succeed; the following guidelines will help you prepare adequately.

• Study electrical textbooks and reference materials that cover the topics included in the test. The National Electrical Code (NEC) handbook is a valuable resource for understanding code requirements. Additionally, there are numerous study guides and practice exams available designed explicitly for electrician apprentices.
• Practice tests are invaluable for familiarizing yourself with the format, content, and time constraints of the actual exam. They help identify areas of weakness and allow you to focus your study efforts accordingly. Many online platforms offer practice tests that simulate the actual exam experience.
• Contact local apprenticeship programs or trade schools that offer electrician apprenticeships. They can guide the specific content and format of the electrician test and may even provide study materials or resources.
• Gain practical experience by assisting licensed electricians or working on electrical projects under supervision. The hands-on experience reinforces theoretical knowledge and allows you to understand how electrical concepts apply in real-world scenarios.
• Collaborate with fellow aspiring electricians and create study groups to discuss and review electrical concepts, share resources, and solve practice problems together. Group discussions can enhance understanding and provide different perspectives on challenging topics.
• You may also have to be a high school graduate in some regions to take the test; therefore, you must have your diploma ready.

Tips to Succeed in the Electrician Apprentice Test

• Start Early and Plan Ahead

Begin your test preparation with sufficient time to cover all the necessary topics. Create a study schedule and allocate specific time slots for each subject to ensure comprehensive practice.

• Focus on Understanding, Not Just Memorization

While memorization is necessary, aim to understand the underlying concepts and principles. This will help you apply your knowledge to various scenarios and problem-solving situations. If you know the concepts, it will be easier for you to understand the questions and supply the answers correctly.

• Practice Time Management

The electrician test is often timed, so practice answering questions within the given timeframe. This will help you develop a sense of pacing and ensure you can complete the exam within the allocated time.

• Take Care of Yourself

Prioritize self-care, including sufficient sleep, exercise, and healthy eating, especially during exam preparation. A well-rested and healthy mind performs better in exams. Arrive at the screening venue to calm your nerves before the test starts.

• Stay Updated

Stay informed about changes and updates in electrical codes and regulations. The electrical trade evolves, and staying up-to-date will not only help you in the exam but also in your future career as an electrician.

If you are interested in pursuing a career as an electrician apprentice, the Electrician Apprentice Test can be an essential step in your journey towards gaining the necessary knowledge and skills to become a successful electrician.
