Preparing for an Oklahoma electrical exam? This guide explains the Journeyman and Contractor license paths through the Oklahoma Construction Industries Board (CIB), the NEC edition currently on the exam, which reference books are allowed, and the exact — and unusually strict — rules for tabs, highlighting, and notes.

Who Regulates Electricians in Oklahoma?
The Oklahoma Construction Industries Board (CIB) licenses electricians statewide, covering Apprentice, Journeyman, and Contractor levels. CIB determines your eligibility to test; PSI Services LLC administers the actual computer-based exam once you're approved.
Which Oklahoma License Do You Need?
| Exam | Items / Time |
|---|---|
| Unlimited Electrical Journeyman | 100 items / 240 min |
| Unlimited Electrical Contractor | 100 items / 240 min |
| Limited Electrical Contractor | 100 items / 240 min |
| Residential Electrical Journeyman | 80 items / 210 min |
| Residential Electrical Contractor | 80 items / 210 min |
| Refinery Electrical Journeyman | 100 items / 240 min |
| Electrical Business and Law (Contractor levels) | 50 items / 120 min |
All exams require 70% to pass. Contractor-level licenses (Limited and Unlimited Electrical Contractor) also require passing the separate Electrical Business and Law exam.
Eligibility Requirements by Classification
- Electrical Apprentice: register with CIB while working under a licensed Electrical Contractor's direct supervision so your hours count toward Journeyman eligibility.
- Unlimited Electrical Journeyman: 8,000 verifiable hours as a registered apprentice under a licensed journeyman or contractor. CIB's materials also describe an accelerated path combining fewer apprentice hours with formal electrical education credit — the exact combined figures are not fully clear from CIB's public materials, so confirm directly with CIB if this applies to you.
- Residential Electrical Contractor: 8,000 verifiable hours total, including 4,000 hours as a Residential or Unlimited Journeyman under a licensed Electrical Contractor.
- Unlimited Electrical Contractor: 12,000 verifiable hours total — at least 4,000 hours as a licensed Unlimited Journeyman, with 6,000 hours in commercial/industrial work under a licensed contractor (up to 2,000 hours may be satisfied by formal electrical education).
- Limited Electrical Contractor: either an electrical engineering degree plus 8,000 hours of field construction/estimating/project management experience, or 16,000 hours of electrical work, estimating, or project management experience.
What Changed Under HB 3215?
Oklahoma's HB 3215, signed May 3, 2024, made several changes worth knowing if you're studying older material:
- Effective November 1, 2024: passing score dropped from 75% to 70%; retest wait dropped from 90 days to 30 days, with unlimited attempts allowed.
- Effective January 1, 2026: continuing education doubled for Journeymen/Contractors to 12 hours every 3 years (6 hours must cover Oklahoma Uniform Building Code Commission–adopted codes); apprentices now need 3 hours of CE per year before reregistering (waived for student apprentices or those enrolled in an approved course).
How to Apply
Submit the appropriate application (Apprentice, Journeyman, or Contractor) to CIB with your experience documentation. Applicants without a current employer to verify hours can use tax records or request a Work History Report from the Social Security Administration. Once CIB approves your eligibility, you'll receive contact information for PSI to schedule your exam date, time, and location.
What Is on the Exam?
Exams are computer-based and delivered at PSI test centers throughout Oklahoma (Enid, Lawton, McAlester, Norman, Oklahoma City, Ponca City, Tulsa, Weatherford, Woodward) and nationwide. You'll get your score immediately on screen, and CIB issues your license once you pass.
What NEC Edition Does Oklahoma Use?
As of our last check, Oklahoma's exam references the 2023 NEC, as revised and adopted by the Oklahoma Uniform Building Code Commission. Per PSI's reference list: NEC Handbooks and spiral-bound copies of the NEC will NOT be allowed in the test center — only a soft-bound codebook works here.
Your exam may require or permit additional references beyond what's included. Always confirm your exact classification's reference list with CIB before purchasing.
What Books Are Allowed?
Oklahoma's electrical exams are open book. Depending on your exam, the allowed references include:
- NFPA 70 — National Electrical Code, 2023 Edition (soft-bound only)
- Code of Federal Regulations, 29 CFR Part 1926 (OSHA)
- Ugly's Electrical References, any edition — unlike some states, Oklahoma explicitly allows this as an exam reference
If you bring in a downloaded/printed reference (like the OSHA CFR from the government website) instead of a bound copy, it must be spiral-bound or hole-punched into a binder, or stapled at the top-left corner — loose printed pages are not allowed.
Are Tabs Allowed?
Yes, but only permanent tabs. References may be tabbed/indexed with permanent tabs only. Temporary tabs, such as Post-it notes, are not allowed and must be removed before your exam can begin.
Can You Highlight Your References?
Yes, but only before exam day. Reference materials may be highlighted, underlined, and/or indexed prior to the examination session.
Can You Write Notes?
No — this is Oklahoma's strictest and most distinctive rule. Unlike Texas and North Carolina, which allow notes written before the exam session, Oklahoma's bulletin states references may not be written in prior to or during the examination session at all. Any candidate caught writing in their references during the exam will have them confiscated and will be reported to CIB. Additional loose papers with your references will also be removed and confiscated.
How to Prepare Your Codebook
- Buy a soft-bound 2023 NEC — never spiral-bound, never the Handbook.
- Add permanent tabs only.
- Highlight and underline before exam day — but do not write any notes, ever, in the book you bring.
- Bring Ugly's Electrical References and the OSHA 29 CFR 1926 if your specific exam requires them.
What Happens After You Pass?
CIB issues your license once you pass. Under HB 3215, Journeymen and Contractors must complete 12 hours of continuing education every 3 years (at least 6 hours covering Oklahoma Uniform Building Code Commission–adopted codes), and registered Apprentices need 3 hours per year before reregistering, unless exempt as a student apprentice or enrolled in an approved course.
Reciprocity
Information needed. We were not able to confirm Oklahoma's current electrician reciprocity terms with other states from CIB's public materials during our research. If you hold an out-of-state license and are considering Oklahoma, contact CIB directly to confirm whether a reciprocity agreement applies to your situation before assuming your credential transfers.
Frequently Asked Questions
Can I write notes in my NEC before the Oklahoma exam?
No. Unlike many states, Oklahoma does not allow writing in your references at any point — not even before the exam session. Highlighting, underlining, and indexing are allowed before the exam; handwritten notes are not.
Is Ugly's Electrical References allowed in the exam room?
Yes, per PSI's Oklahoma reference list, any edition of Ugly's Electrical References is an allowed reference.
Can I use a spiral-bound NEC?
No. NEC Handbooks and spiral-bound copies of the National Electrical Code are explicitly not allowed in the Oklahoma test center.
How many times can I retake the exam?
There's no expiration on your eligibility, and the wait between electrical exam attempts is 30 days, with unlimited attempts allowed. Each attempt carries its own $92 fee per portion.
Does Your Book Spot USA guarantee I'll pass?
No. We sell official, correctly-prepared reference materials — no book or study guide can guarantee an exam result, and we don't claim otherwise.
