What the Board Actually Publishes About Exam Content
Search for "Montana journeyman electrician exam prep" and you will find plenty of material promising a detailed domain-by-domain blueprint with percentage weights. For this exam, that level of detail does not exist in the official source. The Montana State Electrical Board's Electrician Examinations Candidate Information Bulletin (updated June 13, 2024, printed page 4) lists exactly two high-level content headings for the Journeyman Electrician 2020 examination:
- National Electrical Code
- General Trade Knowledge & Theory
The bulletin does not publish percentage weights, per-heading question counts, or an exhaustive list of sub-objectives. That matters for how you prepare. Any site that claims "Domain 1 is 60% of the exam" is inventing a number the Board never released. This guide treats the two headings as the official frame and clearly labels everything else as editorial study advice rather than an official blueprint.
The exam is administered by PSI Services LLC under the Montana State Electrical Board. If you are still sorting out what this credential is and how it differs from similarly abbreviated certifications, the overview at What Is MT-JE? covers the basics, and this article focuses squarely on the content you will be tested on.
Exam Format, Fees and Reference Rules
Before digging into content, it helps to understand the container the content arrives in. The Montana journeyman exam is a computer-based, multiple-choice written test delivered through PSI testing centers, which are available nationwide.
| Item | Current Requirement |
|---|---|
| Exam | Journeyman Electrician 2020 (PSI Services LLC) |
| Questions | 60 multiple-choice |
| Time allowed | 180 minutes |
| Passing score | 70% |
| Exam fee | $75 |
| State application fee | $190 (separate from exam fee) |
| Temporary work permit | $50 (optional) |
| Eligibility and paid exam fee validity | One year each |
Sixty questions in 180 minutes works out to an average of three minutes per question. That is generous by certification-exam standards, but it is generous because many questions require you to find something in a code book, not simply recall it. Time pressure on this exam comes from slow navigation of the NEC, not from the clock being tight on easy items. For a deeper look at fees across the full process, see MT-JE Certification Cost 2026: Complete Pricing Breakdown.
What You May Bring
The exam is open-book with a defined reference list:
- The 2020 National Electrical Code
- Montana Building Codes Amendments
- David L. Hittinger's Printreading based on the 2020 NEC
You may use an on-screen calculator or a compliant silent, battery-operated, nonprogrammable calculator. You may not bring loose or attached additional papers, and you may not write in the references during the exam. Notes, highlighting, underlining and tabs, however, may be added before the exam under the current bulletin. You will also need Board approval, your admission letter and photo identification on test day.
Domain 1: National Electrical Code
The first published heading is the National Electrical Code, and for an open-book exam this domain is as much a skills test as a knowledge test. The question is rarely "Do you remember this rule?" and more often "Can you locate and correctly apply the governing rule fast enough?"
National Electrical Code (2020 edition)
Expect questions that require you to navigate the code book, interpret requirement language and apply it to a described installation.
- Understanding how the NEC is organized: chapters, articles, parts, sections and the role of Annex material
- Knowing how Chapters 5 through 7 can modify or supplement the general rules in Chapters 1 through 4
- Using the index and table of contents efficiently to jump to the correct article
- Applying conductor ampacity, overcurrent protection and conductor sizing tables correctly
- Grounding and bonding requirements, including how the terms differ in practice
- Reading definitions in Article 100 precisely, since a single word can change the answer
Why Tabbing Strategy Matters
Because candidate-added tabs, highlighting and underlining are permitted before the exam, your book preparation becomes part of your strategy. A well-tabbed NEC turns a four-minute hunt into a thirty-second lookup. Tab the major tables (conductor ampacities, conduit fill, box fill), the grounding and bonding articles, and the definitions in Article 100. Highlight the exception language that trips people up, because many wrong answers come from missing an exception rather than misreading the main rule.
Keep in mind you cannot write in the books during the exam, and you cannot bring loose papers. Everything you want to rely on must be physically in the approved references before you sit down.
Montana Amendments and Board Rules
The Montana Building Codes Amendments are an approved reference for a reason: Montana adopts the NEC with state-specific modifications, and statute requires the exam to cover Board rules and applicable Title 37 laws. Treat the amendments as a short, high-value read. A candidate who knows the NEC cold but has never opened the Montana amendments is leaving points available to anyone who has.
Domain 2: General Trade Knowledge & Theory
The second heading covers the knowledge a working journeyman is expected to carry in their head rather than look up. The Board does not publish a sub-objective list under this heading, so the topics below are an editorial reading of what "trade knowledge and theory" reasonably encompasses for a journeyman-level test, not an official outline.
General Trade Knowledge & Theory
Foundational electrical theory, practical trade skills and plan interpretation that support correct NEC application.
- Ohm's law and power relationships in series, parallel and combination circuits
- Single-phase and three-phase fundamentals, including how voltage and current relationships change
- Voltage drop concepts and why conductor length and load matter
- Transformer basics and common connection concepts
- Motor fundamentals, including how load and starting characteristics affect circuit design
- Reading and interpreting electrical plans and symbols
- Safe work practices and common installation methods
Printreading Deserves Its Own Attention
One of the three approved references is a printreading text, which is a strong hint that plan interpretation is in scope. Hittinger's Printreading based on the 2020 NEC pairs plan-reading practice with code references, so working through its drawings gives you double value: practice reading symbols and schedules and practice connecting what a plan shows to the NEC rule that governs it. Treat this book as a study partner, not just an exam-day crutch.
Key Takeaway
Do not treat the two domains as separate silos. A typical question blends theory and code: you calculate a load or current using trade knowledge, then use the NEC to select the conductor, protection or grounding method. Study them in sequence, but practice them together.
Study Topics That Cut Across Both Headings
Because the Board does not publish weights, your best approach is to identify the recurring skill families that appear whichever heading a question falls under. These are editorial study categories, not official domains.
Grounding and Bonding
Grounding and bonding generate more confusion than almost any other area. Candidates mix up grounded conductors, equipment grounding conductors and grounding electrode conductors, and the code treats each differently. Build a one-page comparison of what each conductor does, where it connects and which NEC article governs sizing. Practice by sketching a service from utility connection to panel and labeling every conductor.
Calculation Practice
Calculation questions reward process discipline. Write out each step, convert units carefully and check your answer against the table values in the NEC. Focus on the journeyman-level calculations: branch-circuit and feeder sizing, conductor ampacity adjustments, conduit and box fill, and voltage drop. Note that master-only Major Load Calculations are not part of the journeyman exam, so you can skip master-level service demand calculations and spend that time elsewhere.
Original Practice Questions
Be wary of any resource that claims to reproduce live exam questions. Exam items are protected, and legitimate practice material uses original questions written to mirror the style and difficulty of the real thing. When you work practice items, look for ones that force you to open the NEC and cite an article, since that is the skill the open-book format rewards. You can run timed sets on the MT-JE practice test site to build both speed and book-navigation habits.
Outdated Rules to Ignore: 75% and Factory-Only Markings
A lot of older web content and even some prep-course materials still carry rules from a previous version of the bulletin. Two corrections are worth stating plainly.
| Topic | Older 2022 Bulletin | Current June 2024 Bulletin |
|---|---|---|
| Journeyman passing score | 75% | 70% |
| Reference book markings | Factory-only markings | Candidate-added notes, highlighting, underlining and tabs allowed before the exam |
Administrative Rule of Montana 24.141.503, amended effective May 25, 2024, agrees with the newer bulletin. The 75% figure still exists, but it is the master exam pass mark, not the journeyman one. If a study guide tells you to leave your NEC untouched or to aim for 75%, it is working from superseded information. For a full breakdown of the scoring requirement, see MT-JE Passing Score 2026: Exactly What You Need to Pass.
Scheduling the Two Domains in Your Study Plan
Here is the one place for a study schedule, built around the two domains rather than generic habits. Because the exam is open-book and the NEC is the tool you will lean on most, front-load book familiarity, then layer theory, then integrate. Adjust the length to your own timeline; a deeper plan is available in MT-JE Study Guide 2026: How to Pass on Your First Attempt.
Book Familiarity and Tabbing
- Read the NEC's structure, Article 100 definitions and the Montana amendments
- Tab and highlight major tables, grounding and bonding articles, and key exceptions
- Practice timed lookups: find a rule in under a minute
General Trade Knowledge & Theory
- Review Ohm's law, power, single- and three-phase concepts, transformers and motors
- Work through printreading exercises from the Hittinger text
- Practice journeyman-level calculations step by step
Integration and Full Practice
- Take timed sets that blend theory and code in the same question
- Review every miss by finding the exact NEC article that resolves it
- Sit at least one full 60-question, 180-minute simulation

Eligibility, Retakes and What Comes After
Who Can Sit for the Exam
Under Montana Code Annotated section 37-68-305, eligibility routes include completion of an approved apprenticeship or substantially equivalent electrical program, 8,000 legally obtained practical hours, or 20,000 electrical-maintenance hours with employer certification that includes at least 8,000 practical hours. One detail catches people off guard: the statute expressly excludes experience from an uncompleted apprenticeship from its definition of legally obtained practical experience. Full pathway details are in MT-JE Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Retake Rules
There is no waiting period after a first failure. After a second failure, you must complete an approved eight-hour code seminar, taken after the first failure, before a third attempt. Because eligibility and the paid exam fee each last one year, planning your attempts within that window protects you from paying twice. Scheduling logistics are covered in MT-JE Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
Licensing Differences and Renewal
Residential, journeyman and master credentials differ in scope and, as noted above, in exam content: master-only Major Load Calculations belong to the master exam. After licensure, renewal falls on July 15 in even-numbered years and requires 16 continuing-education hours, including at least eight code hours. The Board's 50% fee abatement applies to the 2026 renewal cycle, not to the exam fee. Whether the credential pays off for you is a separate question, explored in Is the MT-JE Certification Worth It? Complete ROI Analysis 2026 and MT-JE Salary Guide 2026: Complete Earnings Analysis; specific salary amounts were not verified for this article, so treat earnings as a research topic, not a promise.
Frequently Asked Questions
The Board's candidate bulletin publishes two high-level headings: National Electrical Code and General Trade Knowledge & Theory. It does not publish percentage weights or per-heading question counts, so be skeptical of any source that does.
The current journeyman passing score is 70%, per the June 13, 2024 bulletin and ARM 24.141.503. The older 75% figure applies to the master exam, not the journeyman exam.
Yes. The current bulletin permits candidate-added notes, highlighting, underlining and tabs made before the exam. You cannot write in your references during the test or bring loose or attached additional papers.
The exam is the Journeyman Electrician 2020 examination, based on the 2020 NEC. Study from that edition, alongside the Montana Building Codes Amendments and Hittinger's Printreading based on the 2020 NEC.
There is no waiting period after a first failure. After a second failure, you must complete an approved eight-hour code seminar, taken after the first failure, before you can attempt the exam a third time.
With only two published headings and an open-book format, success on this exam comes down to two things: knowing the 2020 NEC well enough to navigate it quickly, and having the theory and printreading foundation to understand what each question is really asking. Build both, practice them together, and use the MT-JE practice tests to confirm you are ready before test day.
