Washington Contractor License Exam Prep
Washington contractors are licensed by the Washington State Dept. of Labor & Industries (L&I). Use the classification list below. Some states fold business questions into the trade exam. We do not sell a standalone Law & Business paper for Washington.
Confirm question count, time, open-book rules, and passing score on the live board bulletin before you sit. We do not publish a single Q-count for every classification on this page, and we do not guarantee a passing result.

How to get licensed in Washington
Washington runs two parallel systems at the Department of Labor & Industries: construction contractors register with a bond and insurance, while electricians hold a genuine certification earned through supervised trainee hours. Many businesses need both.
- Register as general or specialty — the bond differs. A general contractor may perform more than one construction trade and must post a $30,000 bond. A specialty contractor posts a $15,000 bond and may only perform the trade selected. Choose deliberately: the specialty registration is cheaper but it fences in your scope.
- Journey level electrician (EL01): 8,000 hours, half of them commercial or industrial. A general journey level electrician is certified to work in commercial/industrial and all specialty electrical categories. Qualifying requires at least 8,000 hours as an electrical trainee under the supervision of a certified journey level electrician, of which at least 4,000 hours must be in commercial or industrial installations.
- Watch the commercial/industrial split. The 4,000-hour commercial/industrial requirement is where residential-heavy trainees get stuck. Track the split as you accumulate hours rather than discovering the shortfall at application.
- Electrical contractors post a separate bond. An electrical/telecommunication contractor’s licence requires an original $4,000 surety bond or assignment of savings account, which must be maintained for the licence to stay active.
- Carry the required liability limits. Electrical contractor insurance minimums are $20,000 property damage, $50,000 for injury or damage to any one person, and $100,000 for injury or damage to more than one person, each occurrence.
- Contractor registration and electrical licensing are not the same filing. Electrical licensing has its own requirements, separate from general construction contractor registration with L&I. Completing one does not satisfy the other.
