Montana runs its electrical and plumbing licensing through two separate boards, and the plumbing licenses carry a requirement that no question bank can prepare you for.
Plumbing has a practical exam
Both the Journeyman and Master Plumber licenses require a written paper and a separate practical. The written exams are open book against the 2021 Uniform Plumbing Code, with 70 percent to pass: 100 questions for Journeyman, 125 for Master, three hours each.
The practical is three virtual diagrams over two and a half hours. Multiple-choice practice does nothing for it. If you are budgeting preparation time, treat these as two different exams with two different methods, because passing one does not indicate readiness for the other.
One useful detail: the statutes and rules packet is handed to you at the exam. You bring your own tabbed UPC, but you do not need to source the Montana rules in advance.
Electrical is shorter than most states
| Examination | Questions | Time | Pass |
|---|---|---|---|
| Journeyman Electrician | 60 | 180 minutes | – |
| Master Electrician | 80 | 240 minutes | 75% |
| Journeyman Plumber (written) | 100 | 3 hours | 70% |
| Master Plumber (written) | 125 | 3 hours | 70% |
Both electrical papers are open book against the 2020 NEC, which is older than the edition several neighbouring states use. Buying the current NEC because it is current will cost you time hunting sections that have moved.
At 60 questions in 180 minutes the journeyman paper gives three minutes per question, which is comfortable. The master paper adds twenty questions, an hour, and a five-point higher pass mark all at once.
