Exam Details

Montana electrical licensing is administered through the Montana State Electrical Board under the Montana Department of Labor & Industry. Applicants must be approved by the Board before they can register for an exam, and the Board uses PSI as its exam vendor.

Montana’s published exam information sheet includes the following master exam format details:

• Master Electrician exam: 80 questions
• Minimum passing score: 75% correct
• Time allowed: 240 minutes

The same exam information sheet describes the master exam content areas as:

• National Electrical Code
• General Trade Knowledge & Theory
• Major Load Calculations

Montana law also outlines the master electrician examination expectations. Under Montana Code Annotated, the master electrician examination must consist of at least 80 questions and is designed to test knowledge and technical application skills in the national electric code and board rules and applicable laws under Title 37.

Open Book Test

Montana’s published exam information sheet states that the examinations are OPEN BOOK. For the Residential, Journeyman, and Master exams, the sheet lists the materials allowed in the exam room, including the National Electrical Code (2020 Edition) (tabs and/or indexes may be used) and the Montana Building Codes Amendments. It also lists “Printreading,” by David L. Hittinger (based on the 2020 NEC) among the allowed materials.

Open-book testing rewards a different skill set than closed-book testing. It’s not about memorizing entire sections of the NEC—it’s about knowing how the NEC is built and learning how to get to the right answer efficiently:

• Speed with structure: knowing where definitions, general rules, and special rules live.
• Accuracy under pressure: reading carefully, identifying exceptions, and applying conditions correctly.
• Repeatable navigation habits: using the index, article layout, tables, and cross-references without wasting minutes.
• Calculation confidence: setting up problems consistently so you don’t lose points on avoidable errors.

Montana’s exam information sheet also includes calculator restrictions for the exam site (silent, nonprinting, nonprogrammable, and not designed for preprogrammed electrical calculations). It notes that candidates may have personal highlighting, underlining, and notes in approved reference material, and that additional papers are not permitted with approved references.

Licensing Steps

Montana’s process is built around Board eligibility and exam scheduling through PSI. While each applicant’s situation is unique, the published Board process follows a clear flow:

1. Meet the master electrician qualification pathway and prepare your documentation of legally obtained experience and/or education.
2. Submit your application using the Board’s application process and provide the required evidence and fees.
3. Receive Board eligibility notice to take the examination (approved applicants receive an admission letter; the Board also submits notification to PSI).
4. Schedule and pay for your exam with PSI using the instructions in your admission letter and the Board’s exam guidance.
5. Take the open-book exam using a practiced approach for Code navigation, trade theory, and major load calculations.

This is why a combo approach works so well: you’re building master-level skill across the same core areas used on the exam—Code knowledge, trade theory, and calculations—while also training the open-book navigation habits that matter on test day.

State Requirements

Montana Code Annotated lists qualification pathways for a master electrician license. The statute states that an applicant must furnish written evidence of at least one of the following:

• Electrical engineering pathway: being a graduate electrical engineer of an accredited college or university and having a minimum of 2,000 hours of legally obtained practical electrical experience; or
• Journeyman-level pathway: having at least 8,000 hours of legally obtained journeyman-level experience in planning, laying out, or supervising the installation and repair of wiring, apparatus, or equipment for electrical light, heat, and power.

The statute also states that an applicant must file an application on a form furnished by the department, submit appropriate fees, and satisfactorily pass an examination prescribed by the Board.

Reference Books

• National Electrical Code (NEC) 2023 Paperback
  The 2023 NEC is the foundation for modern code knowledge and an excellent resource for building long-term mastery. Use it for navigation practice (definitions, tables, article structure) and for reinforcing how code rules are applied to real installations.

Test Information and Study Materials

Montana’s master exam framework emphasizes NEC knowledge, general trade knowledge & theory, and major load calculations. The best results come from preparing these as connected skills rather than isolated topics.

1) NEC mastery through navigation drills

In an open-book environment, the electrician who moves confidently through the Code has an advantage. Build your skill around “where” as much as “what”:

• Start with definitions and scope so you understand how terms and requirements are intended to be used.
• Practice locating answers without aimless searching—learn which Chapters and Articles typically contain the rules you need.
• Train for exceptions by making it a habit to look for them every time you find a general rule.
• Use tables intentionally by understanding what each column means and which conditions change the outcome.

2) Calculations that stay consistent under time pressure

Major load calculations are listed as a master exam content area in Montana’s exam information sheet, and calculations show up across many NEC-driven topics. A reliable setup method helps keep you accurate when the clock is running:

• Identify the question type (load calculation, conductor sizing logic, overcurrent considerations, service/feeder demand scenarios, etc.).
• Write the knowns and unknowns so your setup is clean before you compute.
• Apply the correct Code rule (or the correct math principle) before you calculate.
• Check reasonableness by asking whether the result fits the scenario described.

3) Trade knowledge & theory that supports Code application

Many master-level questions are designed to test whether you understand the “why” behind the rule. When you strengthen trade knowledge and theory alongside the NEC, you become more efficient at interpreting questions and eliminating wrong answer choices:

• Electrical principles and theory that influence real installations.
• Jobsite decision-making that affects safety and compliance.
• Planning and layout thinking consistent with master-level responsibilities.

How to use this combo effectively

• NEC sessions (navigation): Timed lookups that force you to move quickly and confirm exceptions.
• Calculations sessions: Sets of problems focused on clean setup, consistent steps, and fewer mistakes.
• Mixed review sessions: Rotate between code questions, theory questions, and major load calculations to simulate how the exam feels.

This routine builds confidence the right way: not by guessing what will be on the test, but by strengthening the core skills the exam is built to measure.

How 1 Exam Prep Helps You Reach Your Goal
