If you hold a journeyman license in another state and you’re moving to Colorado, there’s a good chance you can skip the exam. Colorado grants reciprocal licenses without a written test, and it’s one of the more straightforward states to transfer into.
There’s one catch that catches a lot of people, and it’s worth knowing before you fill anything out. Colorado will reciprocate a journeyman license. It won’t reciprocate a master license. Not from any state, not under any circumstances. That’s written into the board’s rules.
Master electricians aren’t stuck, though. There’s a second route that most guides skip entirely, and it’s covered below.
First, What NERA Is
Colorado’s reciprocity runs through the National Electrical Reciprocal Alliance, or NERA. It’s a group of state licensing boards that agreed to recognize each other’s electrician licenses, founded in 1995 and now covering roughly seventeen states. NERA publishes a members map on its own site.
That matters more here than it does in most states, because Colorado doesn’t publish its own list of reciprocal states. Its rule simply says your license has to come from a state that’s a member in good standing of NERA. The list belongs to NERA, and Colorado defers to it.
So throughout this guide, when you see NERA state, it means a state currently in that alliance. Whether yours qualifies is a question for NERA’s membership map rather than any list published by Colorado, including the ones you’ll find on other sites.
The Short Answer
If you hold | Your route into Colorado |
|---|---|
A journeyman license from a NERA state | Reciprocity. No exam. |
A master license from a NERA state | Reciprocity for a journeyman license only. |
A master license and you want a Colorado master | Endorsement, not reciprocity. Different rules. |
A license from a non-NERA state | Endorsement, if you’ve passed a comparable exam. |
A license granted without an exam | Neither. You’ll be testing. |
Reciprocity vs Endorsement: Two Different Doors
Colorado runs two separate paths for out-of-state electricians, and they get confused constantly because most articles only describe one of them.
Reciprocity
This is the fast route. It applies to journeyman licenses only, and it works if your license comes from a state that belongs to the National Electrical Reciprocal Alliance. No Colorado exam, no re-testing, just an application and verification of what you already hold.
One useful quirk: you can hold either a journeyman license or a master license in your home state and still use reciprocity, as long as that license lets you work as a journeyman there. What you get in Colorado is a journeyman license either way.
Endorsement
This is the route nobody writes about, and it’s the one master electricians need.
Endorsement works for residential wireman, journeyman, and master licenses. It isn’t limited to NERA states. What it asks instead is that you’ve already passed a comparable written state exam based on the edition of the NEC currently in effect when you apply, and that you’ve either completed an approved apprenticeship or logged the years of experience Colorado would require for that license.
You can also accumulate those qualifications across more than one state, which helps if you’ve moved around.
So a master electrician from Texas can’t reciprocate into a Colorado master license. They can apply for endorsement instead, and if their exam and experience line up, that’s the door.
Who Qualifies for Reciprocity
Colorado’s rules set out four things you need. All of them, not some of them.
- You hold a journeyman or master license from the licensing state that allows you to work as a journeyman electrician there.
- That license is current, active, and in good standing.
- The state that issued it is a member in good standing of NERA, or has its own agreement with the Colorado board.
- You earned that license by passing a state-administered exam.
That last one does more work than it looks like it does.
Grandfathered licenses don’t transfer
If your home state handed you a license without an exam, usually during a grandfathering window when licensing rules first came in or changed, Colorado won’t reciprocate it. The rule says so directly.
This catches long-tenured electricians more than anyone else, which feels backwards. Thirty years in the trade and a license issued under an old grandfather clause puts you in a worse position than someone who sat the test five years ago. If that’s you, endorsement or the Colorado exam are your options.
Which States Actually Count
Here’s where most articles about Colorado reciprocity go wrong, including some that look authoritative.
Colorado doesn’t publish its own list of reciprocal states. Read the rule and you’ll see it points somewhere else: a state that is “a member in good standing of the National Electrical Reciprocal Alliance.” The list belongs to NERA, not to Colorado.
That matters for a practical reason. NERA membership can change without Colorado announcing anything, because Colorado never published a list to update in the first place. Any article that hands you fourteen state names is quoting a snapshot of NERA membership from whenever it was written.
And those snapshots disagree. Checking the widely cited lists side by side, some include Utah and some include Texas in Colorado’s network. They can’t both be current.
So the answer to “is my state on the list” is that NERA holds it. NERA’s members map is the source worth checking, and it’s the one Colorado itself defers to. If you want it confirmed for your specific license, the Colorado electrical board will tell you directly.
The Experience Behind the License
Reciprocity means Colorado accepts the work you already did rather than making you prove it again. Useful context for what they’re accepting:
License | Hours | Minimum time |
|---|---|---|
Residential wireman | 4,000 | 2 years |
Journeyman electrician | 8,000 | 4 years |
Master electrician | 10,000 | 5 years |
Colorado journeyman applicants going the normal route also have to document 288 hours of classroom training during their last four years of apprenticeship, covering grounding and bonding, code changes, wiring methods, theory and calculations, plus safety training. Reciprocity skips all of it.
How to Apply
- Confirm your issuing state is a current NERA member.
- Check your license is active and in good standing, with no open discipline.
- Confirm your license came from an exam rather than a grandfather clause.
- Complete the reciprocity application through the Colorado Division of Professions and Occupations.
- Have your home state board verify your license directly to Colorado. This is usually the slowest step, so start it early.
- Pay the fee and wait for the license to issue.
The board sits with the Colorado Division of Professions and Occupations at 1560 Broadway, Suite 1350, Denver, CO 80202, reachable on 303-894-7800. Applications run through the division’s electrical licensing portal.
Can you work while you wait?
There’s a temporary work permit, but read the limits before you count on it. It can be issued when you’re approved for an examination, and it lasts no more than 30 days.
Working without a license in the meantime is a bad idea. Colorado fines unlicensed journeyman work at $225 for a first offense, $600 for a second, and up to $2,000 a day after that.
If Your State Isn’t a NERA Member
You’ve still got two options.
Endorsement is the first, and it’s worth a serious look before you assume you’re testing. It doesn’t require NERA membership. What it requires is a comparable state exam based on the NEC edition currently in effect, plus the apprenticeship or experience to match the license you want.
The Colorado exam is the second. Your out-of-state hours generally still count toward eligibility, so you’re proving you know Colorado’s adopted code rather than starting an apprenticeship over.
Moving somewhere else instead? We cover Texas reciprocity and California reciprocity separately, and how license transfers work generally if you’re still deciding where to go.
After You’re Licensed
Colorado renews on a three-year cycle, deliberately timed to line up with the board’s adoption of each new NEC edition. Every renewal needs 24 hours of continuing education, with at least 4 hours on code changes and no more than 4 hours of safety training.
There’s a 60-day grace period after expiry with a late fee. Past that, the license is expired and you can’t work on it until it’s reinstated.
Before You Send Anything
Call the board and confirm your specific situation. Reciprocity arrangements move, NERA membership changes, and fees get revised. The application fee isn’t refundable if it turns out your state came off the list last year.
One phone call is cheaper than finding out afterward.
Frequently Asked Questions
Does Colorado have electrical license reciprocity?
Yes, for journeyman licenses, through the National Electrical Reciprocal Alliance. If your state is a NERA member in good standing and you earned your license by exam, you can apply for a Colorado journeyman license without testing again.
Can I transfer a master electrician license to Colorado?
Not through reciprocity. Colorado’s rules state plainly that a master license may not be granted by reciprocity, regardless of which state you’re coming from. Licensure by endorsement is the route for master electricians, and it has its own requirements.
Do I have to take the Colorado exam?
Not if you qualify for reciprocity. Colorado issues the license without a written exam when you meet all the conditions.
Which states have reciprocity with Colorado?
Colorado doesn’t maintain its own list. Its rule points to states that are members in good standing of NERA, so NERA’s membership is the list. Published lists elsewhere are snapshots that can fall out of date without notice, so check NERA’s members map or call the Colorado board.
How long do I need to have held my license?
Your license needs to be current, active, and in good standing. Colorado also expects it to have been earned by a state-administered exam. Most reciprocity arrangements of this kind expect at least a year of active licensure, so confirm your timing with the board before applying.
What if I got my license without taking an exam?
Colorado won’t grant reciprocity on a license that was granted by grandfathering without a state exam. Endorsement or the Colorado exam are your remaining routes.
Can I work in Colorado while my application is processing?
Only with a temporary work permit, and only for up to 30 days. Working without one carries fines starting at $225 and reaching $2,000 a day for repeat offenses.
How often do I renew?
Every three years, on a cycle timed to the board’s adoption of each new NEC edition. Each renewal needs 24 hours of continuing education.
