How to Pass the Electrician’s Exam (excerpts from Electrician’s Exam Preparation Guide and California Journeyman’s Electrician’s Preparation & Study Guide)

If you’ve been installing electrical systems as an apprentice, helper or unlicensed electrician you can usually make a lot more money as a licensed electrician. Passing the electrician’s exam is usually your ticket to advancement up from the apprenticeship level to master electrician.

Most communities now require that any electrician working without supervision must be licensed. For larger electrical construction projects, many states require the certification of journeyman electricians as well as specialty electricians, such as splicers of high-voltage cable. This licensing trend is increasing as more states recognize the need to protect homeowners from incompetent electricians.

The Electrical Exam
Just about all states now require that electricians pass a demanding exam. These exams are a good test of the examinee’s electrical knowledge. The exams usually center on, and make reference to the National Electrical Code and questions in the exam often include many obscure code references that require genuine Code knowledge, not just common sense. These are hard tests to pass, but there are secrets to studying that can offer you an edge.

The first stage in preparing for your electrical exam is to check with your state board for the requirements, recommended study material, and how to apply. Many of these requirements can be found online at If you meet the license requirements follow the links to find out where the exams are given and the study material required. Often the whole test application process can be done on line thorough your state licensing board.

Once you’ve set your exam date you’ll probably want to prepare for the test. There are probably plenty of schools in your state that will be happy to take your money and spoon-feed you electrical knowledge to help you pass the exam. But you may be able to save your money, study on your own and pass the exam with flying colors. Most electricians who fail the exam, know the material, but don’t know how to study properly.
