- Colorado requires 8,000 qualifying hours over at least four years, including 2,000 hours over two years in commercial, industrial, or similar work.
- You must document at least 288 classroom-training hours from the last eight years, separate from on-the-job hours.
- You take and pass the PSI exam before submitting your license application; passing alone does not establish eligibility.
- The exam is 90 scored questions in 240 minutes, with a 70% passing standard (63 correct).
What "CO-JE" Means Here, and Who Sets the Rules
On this site, CO-JE refers to the Colorado Journeyman Electrician License Exam. It is a project abbreviation, not an official examination code. The license is issued under the Colorado State Electrical Board, which sits within the Colorado Department of Regulatory Agencies, Division of Professions and Occupations. The exam itself is delivered by PSI Services LLC, and in PSI's catalog the examination designation is Journeyman Wireman (JW). That designation excludes the separate assessment for six-plus-year apprentices, which is a different pathway with different rules.
That split matters for how you read requirements. The Board decides whether you are qualified to hold a license. PSI decides whether you can demonstrate knowledge on test day. Satisfying one does not satisfy the other. If you need background on the credential first, see What Is CO-JE? and What Does CO-JE Stand For?.
The Experience Requirement: 8,000 Hours and the 2,000-Hour Commercial Rule
The core experience standard for a journeyman candidate has two parts that must both be met:
- 8,000 qualifying hours of electrical work experience, accumulated over at least four years.
- Within that total, 2,000 hours over at least two years in commercial, industrial, or substantially similar work.
The two-year floor on the 2,000 hours is easy to overlook. It is not enough to cram 2,000 commercial hours into a single busy year, and it is not enough to have eight thousand hours of purely residential work. The commercial or industrial component is a distinct test inside the larger total.
What "substantially similar" means in practice
The phrase "substantially similar" gives the Board discretion, which means your documentation carries real weight. If your work history includes, say, large multifamily buildings, institutional facilities, or heavier-service installations, describe the scope clearly: voltages, service sizes, equipment types, and your role. Vague job descriptions create review delays. Specific ones let the reviewer map your work to the standard.
Document Like a Reviewer Will Read It
Experience is reviewed by the Board, not scored by an algorithm. Build records that answer the obvious questions before they are asked.
- Employer name, dates of employment, and the supervising licensed electrician where applicable
- Type of work performed, with commercial or industrial projects called out separately
- A running tally so the 8,000-hour total and the 2,000-hour commercial subtotal are both visible
- Overlapping jobs or gaps explained rather than left for the reviewer to puzzle over
The 288 Classroom Hours: Documenting Education Separately
Colorado also requires at least 288 hours of classroom training, drawn from the last eight years of training, apprenticeship, or practical experience. These hours are documented separately from your on-the-job hours. Working time on a job site does not double-count as classroom time.
Within the 288-hour requirement, Rule 1.7(D)(1)(b) specifies 10 to 40 hours of OSHA-curriculum safety instruction. That wording is corroborated in the accessible older version of the State Electrical Board Rules and Regulations (3 CCR 710-1). Because the official rule register identifies a version effective July 15, 2026, confirm the current rule wording before you finalize your paperwork, and do not carry over the older document's superseded training lookback or NEC edition.
| Requirement | Current Standard | Common Mistake |
|---|---|---|
| Total experience | 8,000 hours over at least four years | Counting time that overlaps or cannot be verified |
| Commercial/industrial | 2,000 hours over at least two years | Quoting the older 4,000-hour figure |
| Classroom training | At least 288 hours, last eight years | Treating on-the-job hours as classroom hours |
| Safety instruction | 10-40 hours OSHA-curriculum within the 288 | Assuming safety training is additional to the 288 |
Where you got your classroom hours is a practical question worth sorting out early. Apprenticeship programs usually generate these hours as a built-in part of the curriculum, while candidates who came up through other routes may need to assemble certificates and transcripts. Our overview of CO-JE training covers how these pieces fit together.
Older Training and the SB25-165 Exception
Candidates with training older than the eight-year window have a possible route under SB25-165. The enacted law permits the Board to credit older training upon evidence of at least four additional hours on the current or immediately previous NEC, or on other adopted standards.
The law and its signed act are available on the Colorado General Assembly site (SB25-165, "Licensure of Electricians"). Reading the statute directly is worthwhile if your situation does not fit the standard pattern.
Exam First, License Application Second
One of the most commonly misunderstood parts of the Colorado process is sequencing. You take and pass the examination before submitting the license application. The passing score is one prerequisite, not the whole picture. Passing alone does not establish licensing eligibility, because the Board still reviews your documented experience and education.
That has a real planning consequence. It is possible to pass the exam and then discover a documentation gap, such as insufficient commercial hours or an unverifiable stretch of classroom training. To avoid that outcome:
- Tally your hours against the 8,000-hour, 2,000-hour, and 288-hour standards before paying for the exam.
- Gather supporting records while employers and instructors are still reachable.
- Review the Board's current application and forms page so you know what the filing will ask for.
- Schedule the exam, pass it, and then submit the application with your documentation.
For cost planning, note that the exam fee and licensing charges are separate line items. A current initial licensing charge and renewal charge were not independently verified for this article, so check them with the Board; our CO-JE certification cost breakdown explains how to budget for the pieces.
What You Are Qualifying To Sit: Format, Timing, and Fees
Meeting the requirements gets you to the exam, so it is worth knowing exactly what the exam looks like. The following details come from the Colorado State Electrical Board Candidate Information Bulletin (updated June 18, 2026).
| Feature | Detail |
|---|---|
| Format | Computer-based, multiple choice |
| Scored questions | 90 |
| Time allowed | 240 minutes |
| Unscored items | Up to 10 additional; they add 30 minutes |
| Passing threshold | 70%, or 63 scored answers correct |
| Initial exam fee | $78 |
| Retest fee | $73 |
| Scores | Provided after testing |
| Testing provider | PSI test centers |
The 240-minute figure applies to the 90 scored questions. If you receive up to 10 unscored experimental items, your appointment extends by 30 minutes, but you will not know which items are unscored. Answer every question as if it counts. For a deeper look at the scoring line, see CO-JE Passing Score 2026.
Open book, with restrictions
The exam is open book, but the book is supplied by PSI. PSI provides the NEC and a formula page, and an on-screen calculator is available. Personal references are prohibited, and writing, highlighting, underlining, or indexing the supplied references is not allowed. If you have read advice from other states about bringing a personally tabbed NEC, do not apply it here. For Colorado, the practical skill is navigating a clean book quickly.
If you do not pass
The bulletin permits scheduling a retest from the day after a failed attempt, for the next available test date and with the $73 retest fee. It does not promise an immediately available seat, so build some slack into your timeline. No current first-attempt or overall pass rate has been publicly verified, and the 70% passing standard is not a pass-rate statistic. See CO-JE Pass Rate 2026 for what can and cannot be said about outcomes.
The 2026 NEC Transition and the Conflicting Reference Text
This is the part of the 2026 requirements picture most likely to trip candidates. The retrieved bulletin text states that, effective August 1, 2026, questions are consistent with the 2026 NEC and PSI supplies the 2026 NEC. It also says a 2023 book may be requested until December 1, 2026, after which that option ends. However, older introductory and rendered reference text in the same materials still specifies NEC 2023.
Practically, this means studying from a source that matches the edition you will actually be handed. If you are preparing across the transition date, plan to review what changed between editions, especially in areas the exam weights heavily. Our exam dates and scheduling guide covers timing considerations.
Mapping the 13 Content Areas to Your Prep
Once you qualify, preparation should follow the exam's actual content headings. The official bulletin lists 13, with published item allocations that total 90. Official percentage weights are not published, so the figures below are item counts, not percentages.
| Content Area | Published Items |
|---|---|
| General Electrical Knowledge | 11 |
| Services, Feeders, and Branch Circuits | 9 |
| Grounding and Bonding | 14 |
| Overcurrent Protection | 6 |
| Conductors and Cables | 8 |
| Raceways and Boxes | 5 |
| Special Occupancies | 5 |
| Special Equipment | 6 |
| Electrical Devices | 5 |
| Motors | 6 |
| Transformers | 4 |
| Photovoltaics | 2 |
| Electrical Calculations | 9 |
Grounding and Bonding: The Largest Allocation
With 14 of 90 items, Grounding and Bonding is the single largest content area. A candidate who is shaky here is giving up the most points of any category.
- Practice looking up grounding electrode and bonding requirements quickly in the supplied NEC
- Drill the distinction between grounding and bonding, which exam stems often exploit
- Pair this area with Services, Feeders, and Branch Circuits, since the two overlap at the service
Electrical Calculations and General Electrical Knowledge
Calculations (9 items) and General Electrical Knowledge (11 items) together account for 20 questions. The bulletin recommends reviewing electrical theory and common formulas in addition to code navigation.
- Know Ohm's law relationships and power formulas well enough to use them without hunting
- Practice load calculations with the on-screen calculator so the interface is familiar
- Remember that PSI supplies a formula page, but speed comes from knowing what you need before you look
For each area in depth, see our complete guide to all 13 CO-JE content areas, and use the CO-JE study guide to sequence your preparation.
One way to schedule the weeks
If you have roughly a month, front-load the heaviest and most foundational material so you can revisit it.
Grounding and Bonding plus Services
- Largest allocation first, with branch circuits and feeders alongside it
- Practice finding articles fast in the supplied NEC
Calculations and General Knowledge
- Formula fluency and load calculations on the on-screen calculator
Conductors, Overcurrent, Raceways, Motors
- Mid-weight areas that reward steady code navigation
Smaller areas and full-length review
- Special Occupancies, Special Equipment, Devices, Transformers, Photovoltaics
- Timed practice with the CO-JE practice tests

After You Pass: Renewal and Continuing Education
Qualifying is the start, not the end. Colorado licenses run on a three-year renewal cycle with 24 continuing education hours, including at least four hours on NEC changes and no more than four credited safety hours.
There is a notable exemption: initial licenses obtained by examination between October 1, 2023 and September 30, 2026 are exempt from CE until after their first renewal. The current cycle expires September 30, 2026. A prior review also recorded a renewal availability window through November 30, 2026, but that post-expiration window could not be independently revalidated, and it must not be treated as permission to practice on an expired license. Confirm renewal timing directly with the Division of Professions and Occupations.
Key Takeaway
Do the paperwork math before the exam math. Confirm your 8,000 hours, 2,000 commercial hours, and 288 classroom hours first, because a passing score does not rescue an incomplete application. Then confirm the NEC edition PSI will supply for your appointment date.

Frequently Asked Questions
You need 8,000 qualifying hours over at least four years, including 2,000 hours over at least two years in commercial, industrial, or substantially similar work. This reflects the enacted SB25-165 change, which supersedes older 4,000-hour commercial/industrial descriptions.
Yes. You must document at least 288 classroom-training hours from the last eight years of training, apprenticeship, or practical experience, separately from your on-the-job hours. Within that, Rule 1.7(D)(1)(b) specifies 10-40 hours of OSHA-curriculum safety instruction. Confirm current rule wording with the Board.
Possibly. SB25-165 permits the Board to credit older training upon evidence of at least four additional hours on the current or immediately previous NEC or other adopted standards. It is a Board-reviewed exception, not automatic credit, so contact the Board if your history is borderline.
Before. You take and pass the PSI examination, then submit the license application. Passing alone does not establish licensing eligibility, because the Board separately reviews your documented experience and education.
The initial examination fee is $78 and the retest fee is $73. After a failed attempt, the bulletin permits scheduling from the following day for the next available test date, though it does not guarantee an immediate seat. Licensing and renewal charges are separate and were not independently verified here.
