Many knowledgeable electricians have failed their master electrician exam because they did not prepare. Before you take the exam, you should be familiar with the test format, such as whether or not the exam is taken on a computer, how many questions it contains and if its questions are all multiple choice. Make sure that you are familiar with the correct exam; some jurisdictions have different tests for certified licenses (allowing work throughout a state) vs. registered licenses (allowing work only in limited areas).


Although you might have many books related to the electrical industry, invest in a master electrician exam preparation book. Most of these books provide helpful tips, such as information about hazardous locations, in an quick, organized format. Because the books are designed for a national audience, however, you might need extra information for your local exam.

Certain states require at least two years of experience as a journeyman before you can take the master electrician exam. Even though you have real-world experience, consider occasionally studying with other people for additional support and guidance, such as how to approach theory questions. Plus, studying and explaining your reasoning on a subject to another person who will take the master electrician exam will strengthen your skills.


Avoid cramming for the test or believing that years of experience will guarantee a passing score. By planning in advance and allocating enough study time before the test, you will increase your chances of passing during your first, and ideally only, attempt. Find past exam questions and practice answering them using the actual test format. For example, if your state provides four hours to take the exam, then time yourself so that you must finish within four hours. Review your results and highlight areas in which you are weak. Spend extra time studying areas that are difficult for you. For additional help, enroll in a short exam prep seminar.


To become a master electrician, you must demonstrate your familiarity with state regulations and the National Electrical Code by taking a standardized test. You will not be able to respond orally. Make sure that you are rested before the exam because most tests last multiple hours and your endurance will be tested. Remember to take a watch since you probably will not have access to other types of devices that include a clock. Use your watch to help you break down the test. For example, if you will take a 50-question exam in two hours, one approach is to spend 45 minutes on 25 questions and use extra time to answer difficult questions or to review your responses.
