The Number: 63 of 90 Scored Questions
The Colorado Journeyman Electrician exam, delivered by PSI for the Colorado State Electrical Board, uses a straightforward passing standard: 70%. On a 90-question scored exam, that works out to 63 correct answers. You can miss 27 scored questions and still pass.
That sounds generous until you remember what the exam is testing. It is a computer-based multiple-choice exam, open book, with a code book you cannot mark up. Your margin depends less on memorization and more on how quickly and accurately you can find the right article, run the right formula, and avoid the trap answer. This guide breaks down what the 63-question threshold means in practice. For the broader picture of how the exam is built, see our complete guide to all 13 CO-JE content areas.
Scored vs. Unscored Items and Your Clock
The Candidate Information Bulletin separates the exam into two pieces, and confusing them leads to bad pacing.
| Component | Details |
|---|---|
| Scored questions | 90 multiple-choice items |
| Time for scored portion | 240 minutes |
| Unscored (experimental) items | Up to 10 additional items |
| Extra time for unscored items | 30 additional minutes |
| Passing threshold | 70%, or 63 scored answers correct |
| Score reporting | Provided after testing |
The practical consequence: you will not be told which items are experimental, so treat every question as if it counts. The 63-correct requirement applies only to the scored 90. Do not burn time trying to guess which questions are the unscored ones. Instead, budget your 240 minutes across all items you see, knowing the extra 30 minutes are there to compensate for experimental content, not to give you a bonus buffer.
Four hours for 90 questions averages out to roughly two and a half minutes per item. That pace is comfortable for code lookups and awkward for multi-step calculations, so plan to bank time on easy recall questions and spend it on the heavy ones. Our difficulty guide covers where candidates tend to lose time.
A Passing Standard Is Not a Pass Rate
Searchers often mix up two different ideas: the score you need and the percentage of people who reach it. They are unrelated numbers. The 70% figure is the cut score. No current first-attempt or overall candidate pass rate for this exam has been publicly verified, and we will not invent one. If you see a site quoting a specific Colorado journeyman pass percentage without a named, dated source, treat it with suspicion. We discuss what is and is not known on the CO-JE pass rate page.
What you can control is the margin between your practice performance and 63. If your timed practice runs hover right around 70%, you are one unlucky cluster of questions away from a retest. A better target is to see yourself clear of the line consistently, in the domains that carry the most items.
Where the 63 Points Actually Live
Colorado publishes the number of items per content heading, but not official percentage weights. The allocations, in the order the headings appear, total 90 scored items:
| Content Heading | 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: 14 Items
This is the single largest slice of the exam, more than any other heading. A candidate who is shaky here is giving away the most valuable real estate on the test.
- Know the difference between grounding and bonding conceptually, not just by article number.
- Practice locating requirements for grounding electrode systems, conductors, and equipment bonding quickly in an open-book setting.
- Expect questions that ask you to choose between similar-sounding options where one detail changes the answer.
General Electrical Knowledge: 11 Items
The second-largest allocation. Because it is broad, it rewards theory fluency: the bulletin specifically recommends reviewing electrical theory and common formulas in addition to code navigation.
- Be comfortable with Ohm's law relationships and basic power formulas without needing to look them up.
- Treat this heading as a place to collect fast, reliable points.
Because the bulletin offers item counts rather than percentage weights, resist the urge to convert them into decimals and treat them as official weightings. Use the counts as a study-priority guide, nothing more. For a heading-by-heading breakdown, see the domains guide.
The NEC Edition Problem Behind Your Score
The most important variable outside your own preparation is which edition of the National Electrical Code your exam questions follow. The source material contains a genuine discrepancy you should know about:
- The retrieved bulletin text states that, effective August 1, 2026, questions are consistent with NEC 2026, and PSI supplies the 2026 NEC.
- It also states that a 2023 book may be requested until December 1, 2026, after which that option ends.
- Older introductory and rendered reference text in the same materials still specifies NEC 2023.
Those statements do not line up cleanly, and we are not going to paper over that. The availability of a 2023 reference book is not proof that candidates can choose a separate 2023-based exam. Likewise, code adoption and the exam's stated transition are not interchangeable evidence of each other.
Key Takeaway
Before you schedule, confirm directly with PSI which NEC edition your appointment will use and what reference arrangements apply. A few points of difference between editions can be the margin between 62 and 63 correct.
Scheduling timing therefore matters more than usual this year. Our exam dates and scheduling guide covers windows and deadlines.
Open-Book Rules That Affect Your Margin
The exam is open book at PSI test centers, but the rules are narrower than many candidates assume, and they are specific to Colorado. Do not import advice from other states.
- PSI supplies the NEC and a formula page. You are working with their reference materials.
- An on-screen calculator is available.
- Personal references are prohibited. Writing, highlighting, underlining, or indexing the supplied references is not allowed.
- Remote proctoring has not been verified for this exact exam, so plan on a test center appointment.
The practical takeaway: the common advice to "bring a heavily tabbed code book" does not apply. Your speed has to come from knowing the structure of the NEC cold, not from sticky tabs. Practice navigating a clean, unmarked copy so test day feels familiar. Our study guide includes more on building that skill.
Calculation Questions: Cheap Points or Expensive Ones
Electrical Calculations carries 9 items on its own, and calculation-style thinking also shows up inside other headings such as Motors, Transformers, Conductors and Cables, and Services, Feeders, and Branch Circuits. Calculation questions are binary: you get the number or you don't, and a single skipped step produces a plausible-looking wrong answer that is almost certainly among the choices.
Electrical Calculations
Treat this heading as a points reservoir you can drain or fill depending on preparation.
- Memorize the core formulas so the supplied formula page confirms rather than teaches.
- Practice with the on-screen calculator interface so entry errors do not cost you points.
- Work problems that combine a code lookup with arithmetic, since the exam rewards candidates who can do both under time pressure.
- Check units and phase (single-phase vs. three-phase) before committing to an answer.
If you are stronger at code navigation than math, spend disproportionate practice time here. Eliminating arithmetic mistakes is one of the most direct ways to widen your cushion over 63.
What a Passing Score Does and Doesn't Get You
Here is where candidates get tripped up. In Colorado, the sequence is: take and pass the examination before submitting the license application. But passing alone does not establish licensing eligibility. The Board reviews your documented experience and education separately.
Under the current requirements, the eligibility picture includes:
- 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.
- At least 288 classroom-training hours documented within the last eight years of training, apprenticeship, or practical experience, tracked separately from on-the-job hours.
Enacted SB25-165 allows 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. That is a Board-reviewed exception, not automatic credit, and it supersedes older descriptions that listed 4,000 commercial/industrial hours and a four-year classroom lookback. Rule 1.7(D)(1)(b) also specifies 10 to 40 hours of OSHA-curriculum safety instruction within the 288-hour requirement; confirm current rule wording, since a version effective July 15, 2026 appears in the rule register.
If You Miss 63: Retest Mechanics
Falling short is recoverable. According to the bulletin, after a failure you may schedule from the following day for the next available test date, paying the retest fee. Note the wording: "next available," not "immediately available." The bulletin does not promise a seat on any particular day, so seat availability at your test center may stretch your timeline.
| Fee Item | Amount |
|---|---|
| Initial examination | $78 |
| Retest | $73 |
These are examination fees only. A current initial licensing charge and renewal charge were not independently verified and are not included here, so budget separately and check the issuer's application page. Full cost context is in our certification cost breakdown.
If you do miss, use the score report to see where you lost ground and rebuild your plan around those headings rather than simply re-reading everything.
A Four-Week Plan Built Around the Allocations
Rather than a generic schedule, here is one keyed to where the points are. Adjust the length to your own timeline.
Grounding and Bonding + General Electrical Knowledge
- These two headings account for 25 of 90 items, so front-load them.
- Drill grounding electrode, conductor, and bonding lookups on an unmarked code book.
- Refresh theory and core formulas.
Services, Feeders, Branch Circuits + Conductors and Cables
- Combine code navigation with the calculation habits these topics demand.
- Add Overcurrent Protection while the conductor tables are fresh.
Electrical Calculations + Motors + Transformers
- Work timed calculation sets using the on-screen calculator style.
- Review Raceways and Boxes, Electrical Devices, and Special Equipment.
Special Occupancies, Photovoltaics, and Full Simulations
- Cover the small headings so no topic is a blind spot.
- Run full-length, timed simulations and confirm the NEC edition your appointment uses.
You can find practice questions mapped to these headings on the main CO-JE practice test site. For a one-page recap of key facts, see the CO-JE cheat sheet.
Frequently Asked Questions
You need 70%, which equals 63 correct answers out of the 90 scored questions. The up-to-10 unscored experimental items do not count toward that total.
The scored portion allows 240 minutes. If your exam includes unscored experimental items, you receive 30 additional minutes. You will not be told which items are unscored, so treat every question as scored.
No. The 70% figure is the cut score you must reach. No current first-attempt or overall candidate pass rate has been publicly verified, so be cautious about any site quoting a specific percentage without a dated source.
No. PSI supplies the NEC and a formula page, and writing, highlighting, underlining, or indexing the supplied references is prohibited, as are personal references. Confirm the reference edition and appointment arrangements with PSI, since the bulletin describes a transition between NEC editions.
No. You must pass the exam before submitting your license application, but passing alone does not establish eligibility. The Board reviews your documented experience and classroom training. See the requirements guide and the ROI analysis for planning context.
