- OK-ELEC requires 70% on 100 scored questions in 4 hours, administered by PSI for $92.
- Six domains tie for the highest weight, so no single content area can be skipped.
- Up to 10 unscored experimental items may appear, but they don't count against your time limit for scoring.
- Candidates need 8,000 hours of registered experience, including 4,000 commercial/industrial hours, before sitting for the exam.
Why "Pass Rate" Is the Wrong First Question
Every candidate searching for the OK-ELEC pass rate is really asking one thing: "Am I going to walk out of that PSI testing center with a passing score?" The Oklahoma Construction Industries Board doesn't publish a rolling public pass-rate statistic for the Unlimited Electrical Journeyman Examination, and any number you see quoted elsewhere that isn't tied to Oklahoma's specific exam structure should be treated with suspicion. Instead of chasing a figure, it's more useful to understand exactly what the exam demands - because the mechanics of the test tell you far more about your odds than a headline percentage ever could.
The exam is built around 100 scored questions, delivered by computer, with a 4-hour time limit and a 70% passing threshold. That's the entire scoring model. There's no partial credit for domain-specific performance and no separate cut score per content area - you need 70 correct answers out of 100 scored items, full stop. If you want the deepest possible breakdown of how those 100 questions are distributed, the OK-ELEC Exam Domains 2026: Complete Guide to All 13 Content Areas is the companion piece to this one.
How the OK-ELEC Exam Is Actually Built
The Oklahoma Unlimited Electrical Journeyman Examination is administered by PSI on behalf of the Oklahoma Construction Industries Board. The current test outline is based on the 2023 NEC, which means any prep material referencing an older code cycle is functionally useless for scoring purposes. Format-wise, the test is:
- 100 scored, multiple-choice questions
- 4-hour time limit
- Computer-delivered at a PSI test center
- Open book, with restrictions on which code references are allowed
- $92 exam fee, paid separately from licensing costs
Because the format is fixed and well-documented, most of the variance in outcomes comes down to preparation quality rather than luck of the draw. For a full walkthrough of what to study and in what order, see the OK-ELEC Study Guide 2026: How to Pass on Your First Attempt.
Key Takeaway
Because the exam is a flat 70% cut score across 100 scored questions, there is no "easy domain" strategy - every content area contributes equally to your final number.
The Six Tied-for-Top Domains That Decide Your Score
The OK-ELEC outline spans 13 domains, but six of them tie for the highest weight on the exam. That means a majority of your scored questions will draw from this cluster, and neglecting any one of them creates a disproportionate risk to your overall percentage. The full domain list is:
- General Knowledge
- General Electrical Knowledge
- Electrical Installation Requirements
- Services, Feeders, and Branch Circuits
- Overcurrent Protection
- Grounding and Bonding
- Conductors and Cables
- Raceways and Boxes
- Special Occupancies and Equipment (Including Swimming Pools)
- Low Voltage, Alarms, Signaling Systems, and Communications
- Lighting and Signs
- Safety
- Motors and Transformers
Services, Feeders, and Branch Circuits
Candidates must be able to calculate loads, size conductors and overcurrent devices, and apply demand factors correctly under the 2023 NEC.
- Practice load calculations by hand before relying on a calculator
- Know the difference between feeder and branch-circuit sizing rules
Grounding and Bonding
This is one of the most frequently misunderstood areas among working electricians moving into journeyman-level testing.
- Memorize grounding electrode conductor sizing tables
- Understand bonding requirements for services versus separately derived systems
Overcurrent Protection
Expect scenario-based questions requiring you to select the correct protective device rating for a given conductor and load.
- Review standard ampere ratings and next-size-up rules
- Practice tap rule scenarios for feeders
Because these six tied domains carry the heaviest combined weight, they deserve the majority of your study hours. A domain-by-domain breakdown of every one of the 13 areas - including the seven that carry secondary weight - is covered in the OK-ELEC Exam Domains 2026: Complete Guide to All 13 Content Areas.
Unscored Experimental Items and Why They Matter
Up to 10 unscored experimental questions may appear on your exam alongside the 100 scored items. These questions are indistinguishable from scored ones during the test - you won't know which is which - but Oklahoma's time limit accounting excludes the time spent answering them from counting against your scored-question budget. In practical terms, this means:
- You cannot skip a question because you suspect it's experimental; treat every item as if it counts
- An unusually oddly worded or unfamiliar question is not necessarily a sign you're failing - it may simply be a field-test item
- Your actual score is always calculated out of the 100 scored questions, regardless of how many experimental items you encountered
How Experience Requirements Shape Outcomes
Unlike some certification exams that anyone can register for, OK-ELEC has strict eligibility gates set by the Oklahoma Construction Industries Board. Candidates must be at least 18 years old and document 8,000 hours of registered electrical-construction experience, of which 4,000 hours must be commercial or industrial. Up to 2,000 of the total hours may be substituted with formal electrical education.
This matters for pass-rate discussions because the exam is not designed for someone with zero field exposure - it assumes hands-on familiarity with services, feeders, raceways, and grounding systems already gained on the job. Candidates who rush toward the exam the moment they hit the minimum hour threshold, without deliberately reviewing NEC article language for each domain, tend to struggle more than those who pair field experience with structured review. For the complete breakdown of hour requirements and how to document them, see OK-ELEC Requirements 2026: Eligibility, Prerequisites & How to Qualify.
The Open-Book Format: Help or Trap?
OK-ELEC is open book, which sounds like an advantage - and it is, if you know how to use it. But the rules around what you can bring are specific and unforgiving:
- NEC Handbooks are barred
- Spiral-bound NEC copies are barred
- Only permanent tabs are allowed in your code book
- A silent, nonprinting, nonprogrammable calculator is permitted
Many candidates who fail don't fail because they didn't know the material - they fail because they couldn't locate the relevant NEC article fast enough within the 4-hour window. An open-book format punishes disorganization just as much as it rewards preparation. If your code book isn't tabbed by domain before test day, you're effectively taking a closed-book exam under time pressure.
Key Takeaway
Tab your 2023 NEC by domain - Grounding and Bonding, Overcurrent Protection, Services and Feeders - well before test day, and rehearse locating articles under a timer, not just reading them.
A Domain-Ordered Study Timeline
Generic study techniques only matter if they're mapped to OK-ELEC's actual content weighting. Since six domains tie for top priority, your study calendar should front-load those areas while still leaving room for the remaining seven before test day.
General Knowledge & General Electrical Knowledge
- Review 2023 NEC organization and definitions
- Build your permanent tab system
Services, Feeders, Branch Circuits & Overcurrent Protection
- Practice load calculations and device sizing scenarios
Grounding and Bonding & Conductors and Cables
- Drill grounding electrode conductor tables
- Review ampacity adjustment factors
Remaining Domains & Timed Practice
- Cover Raceways, Special Occupancies, Low Voltage, Lighting, Safety, and Motors/Transformers
- Run full 100-question timed simulations
This four-week structure isn't a rigid template - it's a starting point that reflects where the exam's weight actually sits. For a more granular, week-by-week study plan built specifically around OK-ELEC's domain list, the OK-ELEC Study Guide 2026: How to Pass on Your First Attempt goes deeper into each phase.
What a Retake Actually Costs
Failing to hit 70% isn't just a scheduling inconvenience - it carries real financial cost. The exam fee alone is $92 per attempt through PSI, separate from the $75 initial journeyman application and license fee charged by the Oklahoma Construction Industries Board. Licenses also renew annually for $75, with 12 approved continuing education hours required every 36 months beginning in 2026.
| Item | Cost |
|---|---|
| PSI Exam Fee (per attempt) | $92 |
| Initial Journeyman Application & License | $75 |
| Annual License Renewal | $75 |
| CE Requirement (starting 2026) | 12 hours / 36 months |
A single retake effectively doubles your out-of-pocket testing cost without moving your license forward, which is why treating the first attempt as the real attempt - not a diagnostic run - matters financially as much as professionally. For a complete cost breakdown across the entire licensing pathway, see OK-ELEC Certification Cost 2026: Complete Pricing Breakdown.
Concrete Ways to Improve Your Odds
Since there's no published pass-rate figure to benchmark against, the more productive question is what specifically improves your individual odds of hitting 70%. Based on the exam's actual structure, a few factors stand out:
- Simulate the real format. Practice under a strict 4-hour window with 100 questions, not untimed review sessions, using resources like our full-length practice test platform.
- Prioritize the six tied-weight domains - Overcurrent Protection, Grounding and Bonding, Conductors and Cables, Electrical Installation Requirements, Services/Feeders/Branch Circuits, and General Electrical Knowledge - since they carry equal, elevated weight.
- Rehearse code lookups, not just concepts. Being able to state a rule from memory isn't the same as finding it in your tabbed 2023 NEC in under 30 seconds.
- Confirm your hours documentation early. Delays in verifying your 8,000 hours of experience can push your test date later than planned, disrupting your study timeline.

Frequently Asked Questions
There is no widely published, exam-specific pass-rate statistic for the Unlimited Electrical Journeyman Examination. Candidates should focus on the documented scoring mechanics - 70% of 100 scored questions - rather than searching for an unverified percentage.
You need 70% of the 100 scored questions correct, which equals 70 correct answers. Unscored experimental questions, up to 10 of them, do not factor into this calculation. See OK-ELEC Passing Score 2026: Exactly What You Need to Pass for more detail.
No. NEC Handbooks and spiral-bound NEC copies are barred from the testing room. Only a permanent-tabbed standard NEC codebook is allowed, along with a silent, nonprinting, nonprogrammable calculator.
Six domains tie for the highest weight on the exam: General Electrical Knowledge, Electrical Installation Requirements, Services/Feeders/Branch Circuits, Overcurrent Protection, Grounding and Bonding, and Conductors and Cables. These deserve priority review time.
You'll need to pay the $92 PSI exam fee again for each retake attempt. This is separate from the $75 initial license application fee and the $75 annual renewal fee charged by the Oklahoma Construction Industries Board.
