An Idaho electrician license is a credential issued by the Idaho Division of Occupational and Professional Licenses (DOPL), the state agency whose Electrical program page sits at dopl.idaho.gov/ele/. Idaho issues electrician credentials at more than one level - typically journeyman and master - and candidates qualify through a combination of documented work experience and a written licensing examination.

Electrical licensing in Idaho is governed by state statute (Idaho Code Title 54, Chapter 10) and by rules administered through the Idaho Division of Building Safety with an electrical board providing industry oversight.
