Colorado electrician license requirements
The short answer
As of July 2026, Colorado licenses electricians at the state level through the State Electrical Board within DORA's Division of Professions and Occupations. Individuals must register as apprentices and can progress to Residential Wireman (4,000 hrs), Journeyman (8,000 hrs plus 288 classroom hrs), and Master Electrician (10,000 hrs or equivalent paths), each requiring a PSI-administered exam; electrical contracting businesses must register and employ a licensed master electrician as the responsible party. Licenses expire September 30 every 3 years with 24 hours of continuing education per cycle.
Do you need a license to work as an electrician in Colorado?
Colorado licenses electricians statewide, so one credential is valid across the whole state.
Reciprocity (journeyman only) is per National Electrical Reciprocal Alliance (NERA) bylaws: applicant must hold a JW/Master license gained by state-administered exam and held at least 1 year; grandfathered licenses do not qualify. License by endorsement is also available for exam-based state licenses on the current NEC. Exam vendor PSI is named in the Board's official Electrical Licensing Guide.
What licenses does Colorado issue?
The Colorado State Electrical Board (Department of Regulatory Agencies, Division of Professions and Occupations) issues the credentials below for this trade. Boards often list further classes for specialties and business licenses; these are the ones this page covers.
Hours are what each class asks for on its own terms. Where a senior class shows fewer than a journeyman, the board is counting time served after the earlier license rather than from the start; the prerequisite column says which.

How many hours do you need in Colorado?
Colorado requires 8,000 hours of on-the-job experience for a Journeyman Electrician license, plus 288 classroom hours. At a 40-hour week the on-the-job portion is roughly 4 years of full-time work.
What exam does Colorado require?
Colorado Residential Wireman / Journeyman / Master Electrician licensing examinations (NEC-based). Administered by PSI (referenced in the Board's official Electrical Licensing Guide).
How often do you renew, and what continuing education is required?
Renewal period: 3 years, all electrician licenses and electrical contractor registrations expire September 30 every 3 years
Continuing education: 24 hours of CE per 3-year license period for Residential Wireman, Journeyman, and Master (active licenses); at least 4 hours must be in National Electrical Code Changes, no more than 4 hours in safety. Not required for the first renewal after licensure by examination. Compliance audits after each period.
How does the apprenticeship route work?
Apprentices must register with the State Electrical Board before working; hours are earned under a registered electrical contractor, which reports apprentice practical experience to the Board (annual apprentice reporting). Registered-apprentice hours count toward the Residential Wireman (4,000) and Journeyman (8,000) experience requirements, and apprenticeship-program classroom time counts toward the mandatory 288 classroom hours for the journeyman license, but there is no grandfathering: all journeyman applicants must document the 288 classroom hours with a transcript.
Which states does Colorado have license reciprocity with?
Colorado appears in 14 published reciprocal licensing agreements for this trade, covering Alaska, Arkansas, Idaho, Iowa, Minnesota, Montana, Nebraska, New Hampshire, New Mexico, North Dakota, Oklahoma, South Dakota, Utah, Wyoming. Boards write these as agreements between two states rather than as a one-way list, and some publish the list while their counterpart does not, so this counts every agreement naming Colorado from either side. Recognition is never automatic: the board you apply to decides, and most require the original license to have been earned by examination and to be in good standing.
