1.1 Exam Format, Provided References, Scoring & Scheduling

Why the format matters

The Minnesota journeyworker exam is not a vendor test. The Minnesota Department of Labor and Industry (DLI) writes it, approves who may sit for it, and grades it under Minnesota Statutes section 326B.33, subdivision 18, which makes passing "a written or oral examination developed and administered by the commissioner" a precondition to any personal electrical license. DLI publishes the rules of the exam in its Electrical License Examination Guide. Knowing those rules lets you spend your preparation time on the right things: fast navigation of a clean code book, fluent arithmetic, and the knowledge areas DLI lists for the Class A journeyworker (AJ) license.

Exam facts at a glance

The 5½-hour limit gives you a little over 4 minutes per question ($330 \div 80 = 4.125$). That sounds generous, but multi-step load, motor, and box-fill questions can take 8–10 minutes each, so pacing still matters.

What DLI hands you at the exam

DLI provides every reference you are allowed to use:

• The National Electrical Code in soft-cover format, "without tabs or other aids." The edition is the one adopted as part of the State Building Code when you test. Minnesota Rules part 1315.0200 now adopts ANSI/NFPA 70-2026.
• A Laws and Rules Booklet in DLI's current format, containing the Minnesota Electrical Act (Minn. Stat. 326B.31 to 326B.399) and Minnesota Rules chapters 3800 (licensing) and 3801 (electrical procedures).
• An electronic calculator of the common desk type with addition, subtraction, multiplication, division, square root, and percentage keys.

No other materials or electronic devices, including cell phones, are allowed in the building. DLI also warns that "the majority of questions are intended to be answered without the applicant needing to refer to reference materials." Treat the book as a backup for tables and exact numbers, not as a substitute for knowing where rules live.

How DLI writes questions

The guide describes four formats. A single correct answer item has one right statement. A negative-response item asks which choice does not state a rule; DLI says it uses these only in limited instances. An absolute item asks for a number, usually after a calculation, such as the minimum feeder conductor for a group of motors. A common item tests a general rule, such as how to size one equipment grounding conductor run with several circuits.

DLI also tells you how it builds distractors:

• Wrong choices are written to be plausible, not silly.
• Questions may include extraneous information you must ignore.
• Unless a question says otherwise, assume a unity power factor.
• Some questions target code violations installers repeatedly make.
• You are expected to understand the question before reading the choices.

Degree of difficulty

Each question carries a difficulty rating from 1 to 5. Single-rule and definition questions rate low; questions that combine several rules or require several calculations rate high. DLI assigns each license type a target range. Exams for licenses that can serve as the responsible licensed person (Class A master, maintenance electrician, power limited technician) average 2.5 to 3.5. The Class A journeyworker and elevator constructor exams, whose holders work under general supervision of those license holders, average 1.5 to 2.5. Expect mostly direct code application with a steady share of calculations rather than master-level design problems.

Exam-day conduct rules

These rules come straight from DLI and cause automatic failures every year:

1. Bring a picture ID and arrive at least 30 minutes before your start time.
2. You must schedule ahead; walk-ins are not permitted, and you may reschedule only once.
3. Food and drink are permitted. You may use the restroom, but you may not leave the building; leaving before you finish is an automatic failure.
4. Giving or receiving help, or copying questions or making notes about questions, is an automatic failure. You must then submit a new application with new fees.
5. The room may be electronically monitored, and you may not ask the proctor questions about the exam content.
6. Exam materials and scoring keys are nonpublic data under Minn. Stat. 13.34. You will not get a written or oral review of your exam. You may send DLI written comments about specific questions.

Applying, scheduling, and retaking

You apply online through DLI's iMS system, upload any work-experience verification forms not already on file, and pay the $50 application and examination fee. Once DLI approves the application, you receive an email with instructions to schedule. DLI's St. Paul office at 443 Lafayette Road North tests on Tuesdays, Wednesdays, and Thursdays, except in weeks with a state holiday. Regional sites listed by DLI include Bemidji, Detroit Lakes, Duluth, Mankato, Moorhead, Rochester, St. Cloud, Virginia, Willmar, and Winona. Available dates appear under your application in iMS.

If you fail, you may submit a new application 30 days after notification of the failure. Applicants who fail, or who miss a rescheduled exam, must pay a new application and examination fee. After you pass, DLI's result letter explains how to pay the separate license fee and obtain the license.

Applicants with disabilities may request alternative arrangements under the Americans with Disabilities Act with the application. The statute also allows an oral examination for an applicant who provides a written statement from a certified teacher or other qualified professional that a specific reading disability would prevent satisfactory performance on a written test.

Knowledge areas DLI lists for the AJ exam

DLI's knowledge-area table marks the Class A journeyworker column for essentially the entire NEC: Article 90; Chapter 1 general rules; Chapter 2 wiring and protection (branch circuits, feeders, load calculations, services, overcurrent protection, grounding and bonding); Chapter 3 wiring methods; Chapter 4 equipment (cords, devices, panelboards, luminaires, appliances, heating, motors, air conditioning, generators, transformers, capacitors); Chapter 5 occupancies; Chapter 6 equipment; Chapter 7 systems; Chapter 8 communications; Chapter 9 tables; and applied theory (math, Ohm's law, voltage drop, single- and three-phase power, transformer and motor connections, fault current, motor controls, power factor, and troubleshooting). The rest of this guide follows that list.

A practical pacing plan

• First pass (about 90 minutes): answer definition, single-rule, and one-table questions. Flag anything that needs more than two minutes.
• Second pass (about 2½ hours): work standard calculations such as ampacity correction, box fill, conduit fill, motor branch circuits, and transformer currents. Write every step on scratch paper.
• Final pass: finish the longest calculations, then confirm that no question is blank. With no partial credit and no stated guessing penalty, a reasoned answer always beats a blank.
