To learn to be an electrician in Washington, you need to start as a trainee. Electrical trainees and apprentices must have a training certificate and work under the supervision of a certified electrician. They must renew their certificate every 2 years until they pass an exam to become a journey level or specialty electrician.

If you are training to become an (01) journey level electrician, learn about electrical apprenticeship completion requirements.

For specialty electrician exam candidates, there are no apprenticeship completion requirements.

Getting Started

To get started as an electrical trainee:

  1. Make sure you meet the basic age and other requirements. Trainees must be 16 years or older. Employers hiring youth under 18 must have a minor work permit and appropriate parental/school or summer authorization forms. See our publication, Hiring Teens? (F700-142-909), for more information.
  2. To work in the electrical trade, you must have a trainee certificate and work under the supervision of an electrician to gain enough hours of experience to qualify for an electrician examination. You and the electrician supervising you must be on the same jobsite.
    In general, supervision ratios are:
      • 1 trainee to 1 general journey level electrician when doing journey level type work, or
      • 2 trainees to 1 specialty electrician when doing specialty type work.
  3. To apply for a training certificate, you must have a valid Social Security number (SSN) according to state and federal law – RCW 26.23.150 and 42 USC §666(a)(13).
  4. Learn what trainees need to know about education requirements and documenting work experience. (Review all information in Tabs above.)
  5. Apply to become an electrical trainee (See Apply Tab).

If you ever had a trainee certificate, your only option is to renew it. Contact us if you are not able to renew after completing education requirements.

Affidavits of experience

Washington trainees – Do not lose credit for your work experience – Report your hours of experience on time!

Affidavit deadline: From each training certificate expiration date, you have 180 days to turn in affidavits for the previous 2 years. Affidavits received by L&I after the deadline are not approvable. For receipt of delivery, use certified mail. Affidavits are date stamped upon receipt at L&I.

Exception:  Affidavits for experience gained as apprentices in recognized Washington electrical apprenticeship programs may be submitted at any time.

Trainees – Claim credit for hours of experience by submitting one or more Affidavit of Experience for Washington Electrical Trainees (F500-149-000).
Information about fees and where to mail it are on the form.

Common reasons why affidavits are denied:

  • Update fee not paid when required - See affidavit form for explanation.
  • Affidavit includes omissions, errors, or alterations.
  • Affidavit not received within 180 days of expiration when required.
  • Employer’s history of permits and inspections does not support amount or type of experience claimed.
  • Hours claimed cannot be supported by payroll or employment security department records.
  • Date range on affidavit includes hours where a lapse is present. Examples:
    • Trainee does not have a training certificate, or it is expired or inactive.
    • Electrical contractor employing trainee has an expired or suspended license.
    • Certificate of trainee’s supervising electrician is expired or inactive.
    • Trainee is not properly supervised by a certified electrician.

To avoid a reduction of hours or denial because of a lapse within date range claimed, submit separate affidavits that include no lapses within date ranges.

See Chapter 19.28 RCW and Chapter 296-46B WAC for detailed information on affidavits of experience.

Reconsideration available

If you receive a decision that denies training hours, you can request a reconsideration. There is no fee for filing a request, which must be made within 20 calendar days of the date on the initial denial letter you received. The request must include specific reasons why the denial should be reconsidered along with a copy or photo of the letter you received.

Tracking your hours of experience

To ensure the accuracy of hours reported on affidavits, trainees should keep a personal training log to track their hours. For an example, refer to our sample training log. A trainee’s log is strictly for their record keeping. It is not an acceptable form of documentation for contractors or employers.
