Montana journeyman electrician exam: format, NEC edition and fee
The Montana State Electrical Board, in the Department of Labor & Industry, licenses journeyman electricians, and PSI runs the exam. These facts come from the Board's home and exam pages, the PSI exam information sheet the Board hosts (dated 3/27/2025) and PSI's test listing, read on 13 November 2026. Montana sets its own rules and can change them, so confirm with the Board and PSI before you book.
The exam in brief
- Exam: MT Journeyman Electrician (2020)
- Vendor: PSI
- NEC edition: 2020 (see the next section).
- Questions: 60, plus up to 10 unscored experimental questions. The time you spend on those does not come off your exam time.
- Time: 180 minutes
- Passing score: 70%
- Book: open book. Bring the 2020 NEC (tabs and indexes allowed), the Montana Building Codes amendments, and "Printreading" by David L. Hittinger, based on the 2020 NEC. The sheet allows your own highlights, underlining and notes in the approved material. You may not write, highlight, underline or index during the exam, and you may not bring extra papers, loose or attached.
- Calculator: silent, nonprinting and nonprogrammable, and not one built for preprogrammed electrical calculations.
- Fee: $75, and $75 for a retake (PSI's test listing).
- Route: the Board must approve your application first. It then mails or emails an admission letter, and you contact PSI to pay and schedule. The Board says you can test within a week of approval. If you fail for the first time, you can rebook with no waiting period.
- Where you test: seven PSI sites in Montana, in Billings, Butte, Great Falls, Kalispell and Missoula, or a PSI center in another state.

Which NEC edition to bring
The Board says its exams are based on the 2020 NEC, which Montana adopted on 10 June 2022, and PSI's test name carries the 2020 edition. That can change when the state adopts a newer code, so confirm the edition with the Board before you buy a book. Our course is written to the 2023 NEC. Most skills carry over between editions, but section numbers can move, so practice your lookups in the 2020 book you will bring. Washington is the other state in our set whose exam names the 2020 NEC.

What it covers
The sheet describes the journeyman exam in two parts: the National Electrical Code, and general trade knowledge and theory. It gives no item counts by area. There is no law and rules area, though Montana's building code amendments are on the open-book list. Use our journeyman exam outline, whose twelve areas cover the NEC and theory topics state exams share, to plan your study.
How our practice exam fits
Our practice exam is written to the 2023 NEC, one edition newer than Montana's. It is 100 questions in 240 minutes, about 2.4 minutes a question, against Montana's 60 in 180, or 3 minutes a question, so you train at a faster pace than exam day asks. Like Montana's journeyman exam, ours has no law and rules section. Because Montana lets you bring notes in your approved books, plan them before exam day, and the open-book rules guide shows how to set up a book. It is not Montana's exam. See the journeyman exam guide for how other states compare.
