Which edition to study

The official outline names National Electrical Code (NFPA 70), as revised and adopted by the Oklahoma Uniform Building Code Commission, 2023 edition. Study from that edition: questions are written against it, and section numbers and values differ between editions.

What you can bring

Bring the 2023 NEC. You may highlight, underline and index it beforehand with permanent tabs, but you may not write in it, and NEC Handbooks and spiral-bound copies are not allowed. Questions on the code are based only on the 2023 edition as adopted in Oklahoma.

The bulletin also allows 29 CFR Part 1926 (OSHA construction standards) and Ugly's Electrical References. A silent, non-printing, non-programmable, battery-operated calculator without an alphabet keyboard is allowed.

Beyond the code book

Eight of the 100 scored questions are not about the NEC: four on construction safety from the OSHA standards, and four on permits and inspections, preserving structural integrity, and estimating. The course teaches these from the official texts.

Oklahoma's amendments to the NEC

Oklahoma adopts the 2023 NEC with two changes to installation rules (Oklahoma Uniform Building Code Commission, OAC 748:20, Subchapter 10, effective September 14, 2024). In 210.8(F), Exception No. 2 keeps listed HVAC equipment exempt from GFCI protection on a dwelling outdoor outlet with no end date; the NEC as published ends that exception on September 1, 2026. A new 422.16(B)(5) lets a gas-fired furnace that supplies a dwelling unit be cord-and-plug connected, with an equipment grounding conductor, a grounding-type plug, enough ampacity, protection from damage, and a cord no longer than 9 feet. Oklahoma also does not adopt the NEC's informative annexes.

The candidate bulletin lists the 2023 NEC as revised and adopted by the Oklahoma Uniform Building Code Commission, and Code questions are based only on that listed code. The course teaches these two Oklahoma rules and leaves out questions whose answer would differ under them.

How to prepare

Start by attempting questions across the exam subjects. Separate the problems you can solve independently from those where you need help.

For calculations, work on the setup as well as the arithmetic. Identify the unknown, select the method, use the correct units, and check the result.

For code questions, practice locating and applying the relevant sections with your own book. Keep track of questions that take too long, even when you get them right.

As you improve, mix topics and use fresh timed practice to check whether you can choose the right approach without a lesson guiding you.

If you are retaking the exam

Use your score report to identify subjects that need attention. Then work out whether the difficulty is understanding the topic, setting up the calculation, finding the code section, or finishing in time. Each calls for different practice.

Revisit the underlying skills, then check your progress with questions you have not already memorized.

The course

A starting assessment finds what you already know. Each day you get a short list of work: new skills taught with a lesson and a worked example, practice until they stick, review of earlier skills, and mixed questions. Timed practice exams follow the official outline's weights.
