The Short Answer: Why "CO-JE" Is Shorthand, Not an Official Code
On this site, CO-JE stands for Colorado Journeyman Electrician License Exam. "CO" is Colorado, "JE" is Journeyman Electrician, and the "exam" is the licensing test candidates must pass as part of qualifying for a Colorado journeyman electrician license.
One point of honesty up front: CO-JE is a convenient abbreviation used for this project. It is not a verified official examination code published by the state or by the test vendor. If you search the Colorado State Electrical Board's materials or the PSI candidate bulletin for the string "CO-JE," you will not find it. What you will find is "Journeyman Electrician" as the license type and "Journeyman Wireman (JW)" as the PSI examination designation.
The acronym also appears in other fields, and those are unrelated to this exam. Everything in this article refers only to the Colorado electrical licensing exam. If you want a broader orientation, our explainers What Is CO-JE? and CO-JE Meaning cover the same ground from different angles.
Who Actually Issues the License
The licensing authority is the Colorado State Electrical Board, which sits within the Colorado Department of Regulatory Agencies (DORA), Division of Professions and Occupations. The Board's public home for applications, forms, and continuing education information is at dpo.colorado.gov/Electrical. The domain cojeexam.com is an independent exam-preparation property and is not an issuer website.
The Board decides who qualifies for licensure. It reviews your documented experience and classroom training, and it sets the continuing education rules that apply after you are licensed. The examination itself is administered by a separate testing provider.
| Role | Organization | What It Does |
|---|---|---|
| Licensing authority | Colorado State Electrical Board (DORA, Division of Professions and Occupations) | Sets eligibility, reviews applications, issues licenses, governs renewal and CE |
| Testing provider | PSI Services LLC | Delivers the computer-based exam at test centers and publishes the candidate bulletin |
| Exam prep (independent) | CO-JE Exam Prep | Practice materials and study content; not affiliated with the issuer or PSI |
CO-JE, Journeyman, and the PSI "JW" Label
When you register through PSI, you will not see "CO-JE." The examination designation is Journeyman Wireman (JW). That label is a vendor-side naming convention; the license you are working toward is still the Colorado Journeyman Electrician license.
PSI's Colorado listings also include a separate assessment aimed at a different candidate population, namely apprentices with six or more years of experience. That is a distinct pathway and is not what this article or this site is about. Make sure you are booking the Journeyman Wireman exam, not a similarly named appointment.
If you are weighing journeyman against other tiers, such as master or residential wireman, that is a separate comparison. For the pathway and prerequisites, see CO-JE Requirements 2026: Eligibility, Prerequisites & How to Qualify.
What the Exam Measures: The 13 Content Areas
The PSI candidate bulletin lists 13 content headings with published item counts. These add up to the 90 scored questions. The Board does not publish percentage weights, so the item counts below are the only official allocation signal available; we do not calculate or invent percentages from them.
| Content Area | Scored 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 (14 items, the largest block)
This is the single biggest area on the exam, so it deserves the most deliberate practice. Questions typically test whether you can locate the right NEC article quickly and apply it to a described installation.
- Grounding electrode systems and the conductors that connect to them
- Bonding of services, enclosures, and metal raceways
- Equipment grounding conductor sizing and application
- Distinguishing grounded conductors from grounding conductors in scenario questions
Electrical Calculations (9 items) and General Electrical Knowledge (11 items)
Together these two areas account for 20 items and reward fluency with formulas, not just code lookup. The bulletin itself recommends reviewing electrical theory and common formulas alongside code navigation.
- Ohm's law and power relationships, including how they feed into conductor and load questions
- Load calculation steps for dwelling and non-dwelling scenarios
- Voltage drop and conductor ampacity adjustments
- Single-phase and three-phase relationships
The Smaller Blocks Still Add Up
Photovoltaics has only 2 items and Transformers only 4, but the exam does not let you skip them without cost. A few missed questions in small areas can decide a result when the margin is as thin as 63 correct out of 90.
- Motors (6 items): branch-circuit and overload protection logic, and conductor sizing for motor loads
- Special Occupancies (5) and Special Equipment (6): chapter 5 and 6 style requirements for hazardous locations, healthcare, signs, and similar installations
- Transformers (4): primary and secondary protection and conductor relationships
For a deeper walk through each area, see CO-JE Exam Domains 2026: Complete Guide to All 13 Content Areas. These 13 headings reproduce the official examination content outline, not a preparation curriculum, so how you study each one is up to you.
Format, Timing, and Reference Rules
The exam is computer-based, multiple choice, open book, delivered at PSI test centers. The key numbers:
- Scored questions: 90
- Time for scored portion: 240 minutes
- Passing threshold: 70%, which equals 63 correct scored answers
- Unscored items: up to 10 additional experimental questions, with 30 extra minutes allotted
- Results: scores are provided after testing
The unscored items matter for planning. Your appointment may run longer than 240 minutes because of the added experimental questions and their extra time, and you will not be told which items are unscored. Treat every question as if it counts. For the full scoring explanation, see CO-JE Passing Score 2026: Exactly What You Need to Pass.
Because no remote-proctoring entitlement was verified for this exam, plan on an in-person PSI test center appointment.
The NEC Edition Question You Should Verify
This is the part of the exam most likely to trip up a careful candidate, because the source documents do not fully agree. The retrieved candidate bulletin states that, effective August 1, 2026, questions are consistent with NEC 2026 and that PSI supplies the 2026 NEC. It also says a 2023 book may be requested until December 1, 2026, after which that option ends. At the same time, older introductory and rendered reference text in the same materials still refers to NEC 2023.
Two cautions follow from this conflict:
- The availability of a 2023 reference book is not proof that you can choose a separate 2023-based examination. Do not assume the question set changes with the book you request.
- State code adoption and the exam's stated transition are not interchangeable evidence. What Colorado has adopted for installations and what the exam is written against are separate questions.
Key Takeaway
Before your appointment, confirm directly with PSI which NEC edition you will be given and how any 2023 request is handled. Then study from that edition's article numbering and wording, since changed sections are exactly where candidates lose points.
Eligibility and the Order of Operations
The Colorado sequence is the opposite of what some candidates expect: you take and pass the examination before submitting the license application. Passing the exam alone does not make you licensed. The Board reviews your documented experience and education separately.
Experience hours
- 8,000 qualifying hours over at least four years
- Within that, 2,000 hours over at least two years in commercial, industrial, or substantially similar work
These figures reflect the enacted SB25-165, signed June 3, 2025, which supersedes older descriptions that cited a 4,000-hour commercial/industrial figure and a four-year classroom lookback. If you are reading an older forum thread or a dated PDF, check it against the current figures.
Classroom training
- Document at least 288 classroom-training hours within the last eight years of training, apprenticeship, or practical experience, tracked separately from on-the-job hours.
- Rule 1.7(D)(1)(b) specifies 10 to 40 hours of OSHA-curriculum safety instruction within that 288-hour requirement. Confirm the current rule wording, since a version effective July 15, 2026 appears in the official rule register.
- SB25-165 lets the Board credit older training if you show at least four additional hours on the current or immediately previous NEC or other adopted standards. That is a Board-reviewed exception, not automatic credit.
For the full picture of qualifying and documenting, read CO-JE Requirements 2026. Application forms are on the Board's Applications and Forms page at dpo.colorado.gov/Electrical/Applications.
Costs, Retakes, and Renewal
| Item | Amount or Rule |
|---|---|
| Initial examination fee (PSI) | $78 |
| Retest fee | $73 |
| Member/non-member pricing | None published |
| License application and renewal charges | Separate from the exam fee; not independently verified here |
The exam fee and the licensing charges are two different line items. Budget for both, and confirm current licensing charges with the Board before you apply. A fuller breakdown is in CO-JE Certification Cost 2026: Complete Pricing Breakdown.
If you do not pass
The bulletin permits scheduling a retake from the day after a failed attempt, for the next available test date and with the retest fee. It does not promise an immediately open seat, so availability at your nearest center can stretch the gap. See CO-JE Exam Dates 2026 for scheduling considerations.
Renewal and continuing education
- Colorado electrician licenses renew on a three-year cycle requiring 24 CE hours.
- At least four hours must cover NEC changes, and no more than four safety hours may be credited.
- 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.
Mapping Your Study Weeks to the Exam Blueprint
You do not need an elaborate method here. The published item counts suggest where time pays off most, and an ordering that front-loads the heaviest and most foundational areas works well. This is an editorial suggestion, not an official plan.
Grounding and Bonding, plus NEC navigation
- Work the largest block first (14 items) while your energy is highest
- Practice finding articles fast in the edition PSI will supply
Calculations and General Electrical Knowledge
- Drill formulas and load calculation steps (20 combined items)
- Use the on-screen calculator in practice so the workflow is familiar
Services, Feeders, Branch Circuits, Conductors, and Overcurrent Protection
- These areas interlock, so study them as one connected sequence
Motors, Transformers, Special Occupancies, Special Equipment, Devices, Raceways, and Photovoltaics
- Cover the smaller blocks, then run a timed full-length practice set
For a complete plan, see CO-JE Study Guide 2026: How to Pass on Your First Attempt, and when you are ready to test yourself against realistic questions, try the practice tests on the main site. If you want a quick fact sheet to keep nearby, the CO-JE Cheat Sheet 2026 condenses the key numbers.
Frequently Asked Questions
On this site, CO-JE stands for Colorado Journeyman Electrician License Exam. It is a project abbreviation rather than an official examination code. The state license is the Colorado Journeyman Electrician license, and PSI lists the exam under the Journeyman Wireman (JW) designation.
The Colorado State Electrical Board, within DORA's Division of Professions and Occupations, sets licensing rules. PSI Services LLC delivers the computer-based exam at its test centers. Independent prep sites such as ours are not affiliated with either.
The exam has 90 scored multiple-choice questions in 240 minutes, and you need 70%, or 63 correct, to pass. Up to 10 unscored experimental items may be added with 30 extra minutes. See our passing score guide for details.
No. PSI supplies the NEC and a formula page, and an on-screen calculator is available. Personal references are prohibited, and marking up the supplied references is not allowed. Confirm the NEC edition with PSI before your appointment, since the bulletin describes a dated transition.
Yes. The sequence is to take and pass the exam, then submit your license application. The Board separately reviews your 8,000 qualifying hours and 288 classroom-training hours, so a passing score by itself does not establish eligibility. See CO-JE Requirements 2026 for the full breakdown.
