ExploreAbout this exam
The Colorado Electrical credential is issued through the State Electrical Board, which sits within the Division of Professions and Occupations of the Colorado Department of Regulatory Agencies. The board licenses Residential Wiremen, Journeyman Electricians and Master Electricians, and it also oversees apprentice reporting, permits and inspections for areas without local enforcement. Colorado has adopted the National Electrical Code as its installation standard, and the board's rulemaking docket shows it tracking code editions as they are published, so candidates should expect code-based material rather than purely state-specific content. Licensees hold an active credential for a three-year license period and must complete at least 24 hours of continuing education during each period; electricians licensed by examination during the current period are exempt until after their first renewal. Renewal windows, CE acceptance rules and board policies are published on the board's website and change through rulemaking, so verify current requirements at dpo.colorado.gov/Electrical before you apply, schedule an exam or buy a prep course.

What you'll study
About CO Electrician preparation
Who issues the Colorado electrician license?
The State Electrical Board, part of the Division of Professions and Occupations within the Colorado Department of Regulatory Agencies. The board is based at 1560 Broadway, Suite 1350, Denver, CO 80202, and can be reached at 303-894-7800. Licensing questions go to [email protected]; permit questions go to [email protected].
What code edition should I study?
Colorado adopted the National Electrical Code as its standard in 1965, and the board has noticed a May 27, 2026 rulemaking hearing on Rule 1.5 to adopt the 2026 NEC. Until that rulemaking concludes, confirm the edition in force with the board before you buy materials, because a future adoption is not the current standard.
How long is a Colorado electrician license valid, and what CE is required?
Licenses run on a three-year period. Residential Wiremen, Journeyman Electricians and Master Electricians with an active license must complete at least 24 hours of continuing education during each three-year license period. Electricians who received an initial license by examination during the current period are not required to complete CE until after their first renewal.
When do licenses expire and when can I renew?
The board's site states that licenses expire on 9/30/2026 and can be renewed through 11/30/2026, and that renewal is open through the DPO Online Services Renewal System. Dates shift with each cycle, so check the renewal page on dpo.colorado.gov/Electrical rather than relying on a date you saw in a prep course.
Can I take continuing education from any provider?
No. The board accepts CE courses only if they are taken with a provider or vendor that has attested to the board that its courses and instructors meet the requirements of board rule. Confirm the provider's attestation before you pay, and keep completion documentation in case your renewal is audited.
How should I split my study time?
Work in four passes: licensing and board rules, then code articles, then permits and inspections, then CE and renewal. Code is the largest body of material, so give it the most repetitions, but do not skip the administrative topics, since they are the easiest points to secure and the most commonly neglected.
What trips candidates up most often?
Two things: studying an outdated code edition, and ignoring administrative content. Board rules, renewal dates, CE acceptance and permit and inspection procedures are published and testable, yet candidates tend to skim them. Also verify every figure against the board's current page, because rulemaking and legislative changes move requirements between cycles.
Where do I file a complaint or verify a license?
The board's site links a license lookup, a downloadable licensee and discipline list, and a complaint form for filing against a licensee. Use the lookup to confirm a license is active before hiring or before citing your own status, and route discipline or practice questions to [email protected].
