Frequently asked questions
How is the Minnesota Class A Journeyworker exam structured?+
One exam of 80 multiple-choice questions in 5½ hours, all worth the same, and you need 70%. DLI rates journeyworker questions easier on average than master questions, but stems include extra information and every wrong answer is plausible.
Which code edition is the exam on?+
The 2026 NEC, in effect in Minnesota since August 17, 2026. The current exam format has been in place since September 8, 2026. Older prep material cites rules that have since moved, such as load calculations, now in Article 120 instead of Article 220.
Can I bring my own code book or calculator?+
No. The Department of Labor and Industry supplies a soft-cover 2026 NEC without tabs, the Laws and Rules Booklet (the Minnesota Electrical Act and Rules 3800 and 3801) and a basic desk calculator. No other materials are allowed, and copying questions or making notes about them is an automatic fail.
Does Minnesota publish how many questions come from each topic?+
No. DLI lists the knowledge areas each license is tested on, but not how many questions come from each. Our 80-question practice exam follows our own blueprint, weighted by NEC chapter from that list, with a small Minnesota laws and rules section.
What if I fail?+
Results are emailed, generally within two weeks. If you fail, you can apply to retake the exam 30 days after you are notified, with a new application and the $50 application and examination fee. Exams are scheduled ahead of time; walk-ins are not accepted.
How are the calculation questions checked?+
Every calculation answer — and every wrong option — is computed by code from the 2026 NEC tables and rules, not written by hand. The explanation walks through each step with the section it comes from. Like the real exam, questions assume unity power factor unless they say otherwise.
What do I need before I can sit the exam?+
48 months of experience, at least 24 of them wiring for and installing electrical wiring, apparatus and equipment (Minnesota Rules 3800.3520). A two-year post-secondary electrical program can count for up to 12 months. Apply to DLI with the $50 application and examination fee; the license fee is due after you pass.
What continuing education do I need to renew?+
16 hours per renewal, at least 12 of them on the National Electrical Code; up to 4 may be related technical subjects or the Minnesota Electrical Act and Rules.
