The city we could not read

Denver Electrician License CO: Exams, Classes, Rules

Denver is the only Colorado jurisdiction we found running its own electrical examinations, and it is also the one whose own pages would not load for us. So this page is unusually careful: one confirmed document, several confirmed training centers, and a plain list of what nobody should tell you without a source.

The license starts with the state

C.R.S. 12-115-109(1) bars anyone from working at the trade of journeyman electrician, master electrician or residential wireman in Colorado without a license from the division or a temporary permit. That applies in Denver like anywhere else.

The State Electrical Board itself is a Denver address: 1560 Broadway, Suite 1350, Denver, CO 80202, on 303-894-7800, at dora_electricalboard@state.co.us.

So a Denver electrician's first card is the state one, and the license path page is where that starts. What Denver adds on top is the part we could not confirm.

Denver's own exams, and their code edition

The ICC contractor and trades examination information bulletin for Denver, dated June 3, 2026, lists two Denver electrical examinations.

Exam 380, Colorado (Denver) Journeyman Electrical Signal: 40 multiple-choice questions, 3-hour time limit, PearsonVUE: $115, open book, referencing the 2014 National Electrical Code, the 2015 International Building Code and the 2016 NFPA 72.

Exam 377, Colorado (Denver) Electrical Signal Supervisor: 40 multiple-choice questions, 2-hour time limit, PearsonVUE: $115, open book, referencing the 2015 International Building Code, the 2014 National Electrical Code and the 2013 NFPA 72.

The 2014 edition is four editions behind the state code, which has been the 2026 edition since July 15, 2026. Different vendor, different edition, different rules. The Denver exams page has it in full.

What we could not read, stated plainly

Every denvergov.org page we tried returned a robots error, on 5 September and again on 7 September 2026. That includes the electrical certificates page, the contractor licensing pages, the supervisor certificates page and the contractor license application form. The mirror host failed the same way, a municipal code library returned metadata only, and a code hosting site returned a robots error. The 2025 Denver Building Code PDF could not be fetched either.

So all of the following are unconfirmed here: Denver's full list of electrical certificate classes, their prerequisites, whether a state license is required before a Denver certificate, the fees, the renewal cycle and any continuing education.

We are not going to fill those gaps from a third party. Call the City and County of Denver, and treat any page that gives you Denver certificate detail without naming its source with suspicion.

Denver moved its electric standards on a different date

Denver Community Planning and Development posted an item titled New electric standards to be effective Aug. 1 for 2026, and a second titled New electric standards adopted on August 1.

Those are titles we saw in search results. Both pages are on denvergov.org and neither would load, so we are recording the titles and confirming nothing about their contents.

What is confirmed is the state date: the Colorado state electrical code became the 2026 National Electrical Code on July 15, 2026 under rule filing 2026-00171. If Denver's own date is August 1, that is a second gap on top of the seventeen days between the state code and the state exam. The timeline page keeps the record.

Where to train in Denver

The DJEATC application, and its September 30 date

The training center publishes its requirements, and one of them is a deadline three weeks out.

Applications close on September 30, 2026 and reopen on February 1, 2027. There is a $35.00 fee to apply, charged when the online application is started and described as non-refundable.

What you need: a current and valid driver's license, with identification cards and instruction permits not accepted, plus a second identity document from a Social Security card, birth certificate or passport, plus a high school, college or GED diploma or transcripts stating your graduation date, plus a DD-214 if applicable.

The order runs: documents to djeatcapplications@outlook.com, an approval email, the online application, a Personal Experience Form from GAN Human Resources to be completed within two weeks from when you first receive the email from GAN, the aptitude test, then a background check for Inside Wireman applicants only. The aptitude test components are named as Paper Folding, Numerical Computation, Numerical Reasoning, Reading Comprehension and Mechanical Reasoning.

How many nights a week, which nobody agrees on

Three sponsor pages describe the same Inside Wireman program and give three answers.

The training center's own page says courses usually take place in the evening, twice a week, with the occasional Saturday class. The NECA chapter page says apprentices work at least 40 hours a week while attending class one night a week. IBEW Local 68's page says two nights a week.

Two of the three say twice a week. We are not resolving it, and if the schedule matters to your work life, ask the training center directly.

The center's own page does add one thing worth knowing: a requirement of completing the Inside Wireman program is earning your journeyman's license. Neither the Denver nor the Colorado Springs joint center publishes its total on the job or classroom hours.

Where Denver candidates sit the state exam

PSI's bulletin lists two Denver area sites: Denver (Centennial) at 12150 E. Briarwood Ave, Suite 270, Centennial, CO 80112, and Denver (Wheat Ridge) at 4891 Independence St #220, Wheat Ridge, CO 80033.

Both are outside the city limits, and the Englewood site at Centennial Airport and the Broomfield site at Jeffco Airport are also within reach.

The paper is 90 scored items in 240 minutes with 63 correct to pass, at $78. PSI supplies the code book and you may not mark it. The test day page has the identification rules.

What we do not publish

We do not publish a Denver pay figure. Our Colorado source file carries no wage research, so there is no Bureau of Labor Statistics number behind anything we could print, and we would rather leave a gap than fill it with a remembered figure.

What we can give you is scale from the state's own licensing data: 12,549 active journeyman electricians, 7,441 active masters, 2,032 active residential wiremen and 4,789 active contractor registrations across Colorado in September 2026.

Questions people ask

Do I need a Denver electrician license?

Denver appears to issue its own electrical certificates on top of the state license, but every denvergov.org page we tried returned a robots error, so the classes, prerequisites and fees are unconfirmed here. The state license is required either way under C.R.S. 12-115-109(1).

Does Denver run its own electrician exams?

At least two. The ICC bulletin dated June 3, 2026 lists exam 380 Journeyman Electrical Signal and exam 377 Electrical Signal Supervisor, both through Pearson VUE at $115, both open book and both referencing the 2014 National Electrical Code.

Where is the electrical apprenticeship in Denver?

The Denver Joint Electrical Apprenticeship and Training Committee at 5610 Logan St, Denver, CO 80216, which serves IBEW Local Union 68 and the Rocky Mountain Chapter of NECA. Emily Griffith Technical College also runs an Electrician Registered Apprenticeship at 1860 Lincoln St.

When can I apply to the Denver JATC?

Applications close September 30, 2026 and reopen February 1, 2027, with a $35.00 non-refundable fee charged when the online application is started.

Where do Denver candidates take the state exam?

PSI lists Denver sites at 12150 E. Briarwood Ave, Suite 270 in Centennial and 4891 Independence St #220 in Wheat Ridge. Englewood and Broomfield sites are also nearby.

Which code edition applies in Denver?

The state code became the 2026 National Electrical Code on July 15, 2026. Denver posted items titled New electric standards to be effective Aug. 1 and New electric standards adopted on August 1, but neither page would load for us, so Denver's own date is unconfirmed.
