Why Exam Prep?

To get any level of electrical license, you must pass the appropriate state examination related to the work you will be doing.

Specific reference materials are allowed during the test, but strict time requirements and other restrictions make studying a worthwhile investment in yourself and your future career.

See how our comprehensive study guide and practice tests will help you know exactly what subjects are included in your electrical licensing test.

Examination Information

The Department of Labor and Industries (L&I) exam requirements help make sure that every person submitting a license application has a practical understanding of the National Electrical Code (NEC), the Revised Code of Washington (RCW), and the Washington Administrative Code (WAC).

Other important details include:

  • You have one year to pass with a minimum 70% score once approved by L&I
  • Exams are administered by PSI and can only be taken at a designated test center
  • All questions are computer-based, and final results are displayed immediately
  • If you fail a specific section, you can schedule a retest for that part after 14 days

License-Specific Prerequisites

General Journey-Level Electricians may perform all types of electrical and telecommunications installations.

They cannot register for their exam until they complete the education and work experience requirements of a registered electrical apprenticeship.

Master-Level licensees can perform all journey-level work as well as supervise other electricians to make sure that their work complies with all applicable laws and rules.

Applicants need at least four (4) years of experience as a certified general electrician to qualify.

Administrators also ensure that electricians follow the laws but have no prerequisites because they are not certified to perform any electrical work themselves.

Reference Materials and Time Limits

You are allowed to bring print copies of any original, copyrighted material, including code books, into the test center with you. However, any books you bring cannot be written in. Only highlighting, underlining, or permanent subject tabs are allowed.

  • The journey-level exam gives apprentices four (4) hours to answer 77 questions
  • Prospective master-level and Administrator licensees have seven (7) hours to answer 110 and 92 questions, respectively

Although the exams are open book, you are still expected to have a working grasp of all relevant codes and general math and electrical theory computation.

Don't waste valuable time on test day searching through books for a specific answer or concept. Use our training resources to build and reinforce the knowledge required to pass on your first try.

Frequently Asked Questions

How do I register for the exam?

  1. Verify that you meet all education and experience qualifications, and submit an application to L&I.
  2. Once approved, you have one year to schedule your appointment on the PSI website or call 1-855-834-8751.
  3. Electrician license candidates will need to provide their Unique ID (WLI_ID_Number) provided on the L&I eligibility notice. Administrators don't need approval.
  4. Review PSI's test taker experience guide before your scheduled appointment.

What other study tips can I use?

If you struggle with information retention or experience test day anxiety, try using some of these methods in addition to our resources:

  • Set a timer and break up study sessions into shorter durations to help keep you focused.
  • Write notes by hand as much as possible. Studies show that using this fine motor skill helps improve recall and conceptual understanding.
  • Try teaching specific topics and concepts to friends or family members. There is evidence that using this method, often called the Feynman Technique, helps identify your own knowledge gaps.

Do I need to retest when I renew my license?

Only if you allow your license to stay expired for over 90 days. Otherwise, you only need to complete 24-hours of state-approved continuing education every three years for renewal.

What Electricians Think
