Which edition to study
The official outline names National Electrical Code (NFPA 70), 2026 edition. Study from that edition: questions are written against it, and section numbers and values differ between editions.
What you can bring
Nothing. The 2026 NEC and a formula page are provided at the test center. You may not write in, highlight, underline or index them, and you may use no other materials. An online calculator is provided.
Until December 1, 2026 you may ask for the 2023 NEC instead; after that date only the 2026 book is provided. Because the book is not your own, practice finding sections from the table of contents and the index rather than from your tabs.
The code Colorado enforces
The State Electrical Board adopts the 2026 NEC for installations from August 1, 2026 (3 CCR 710-1, Rule 1.5 A), with no changes to the code's text. Rule 1.5 C separately requires permit applicants for electric vehicle power transfer infrastructure to meet the Colorado Energy Office's requirements for multifamily buildings, from its Model Electric Ready and Solar Ready Code; those are not part of the NEC. The candidate bulletin says the exam questions are consistent with the 2026 NEC book, which is provided at the test center, so the questions follow the NEC as published and this course teaches the code as published.

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.
