The Number: 70% on 80 Questions
If you are preparing for the Minnesota Class A Journeyworker Electrician exam (the credential most people search for as the Minnesota journeyman electrician exam), the headline figure is simple: the Minnesota Department of Labor and Industry (DLI) requires a 70% passing score. The exam has 80 questions and a five-hour-thirty-minute time limit. DLI both issues the license and administers the examination, so there is no separate national certifying body setting a different cut score.
That sounds straightforward, but the real work is understanding what that 70% demands in practice: how items are scored, what you are allowed to bring, which code edition you will be tested on, and how the timing of the 2026 NEC transition affects your preparation. This article walks through all of it. If you want the broader preparation picture, pair this with our MN-JE study guide, and for the content map behind the score, see the complete guide to all 11 content areas.
What 70% Actually Means in Question Terms
On an 80-question exam, a 70% requirement translates to 56 correct answers if every item is worth one point and the score is a straight percentage of items. That is a useful planning target: you can miss up to 24 questions and still meet the stated threshold. When you take timed practice sets, track your score against this ratio rather than against an abstract feeling of readiness.
Two cautions apply. First, DLI states the requirement as a percentage, and candidates should treat the practical target as at least 56 of 80 while aiming well above it for a safety margin. Second, because some items require selecting several correct options, your effective error rate can rise faster than you expect if you tend to get "mostly right" on those items. A near-miss earns nothing.
| Exam Parameter | Minnesota AJ Exam |
|---|---|
| Administrator and issuer | Minnesota Department of Labor and Industry (DLI) |
| Number of questions | 80 |
| Time limit | 5 hours 30 minutes |
| Passing requirement | 70% |
| Planning target at 70% | 56 of 80 correct |
| Application or reexamination fee | $50 |
| Reference materials | Department-supplied, untabbed softcover NEC and Laws and Rules Booklet |
| Calculator | Department-provided desk calculator |
With five and a half hours for 80 questions, you have roughly four minutes per question on average. That is generous compared with many licensing exams, but code lookups and multi-step calculations consume time quickly, so pacing still matters. Our difficulty guide breaks down where candidates typically lose minutes.
How Each Question Style Is Scored
The AJ exam is not a single uniform multiple-choice format. DLI uses three item styles, and each one rewards a slightly different skill:
- Single-correct-answer items: The familiar format. Choose the one best answer.
- Multiple-correct-answer items: More than one option is correct, and you must select the complete correct set. There is no partial credit.
- Negative-response items: You are asked to identify the option that is not correct, not permitted, or does not apply.
Negative-response items deserve their own drill. Under time pressure, candidates commonly read the stem, find a true statement in the options, and select it, forgetting the question asked for the exception. Build a habit of underlining the qualifier (NOT, EXCEPT, NOT permitted) before you evaluate any option.
What the Score Covers: AJ Knowledge Areas
The exam tests code application, calculations, and theory. DLI's Electrical license examination guide (2026 NEC edition) lists eleven preparation and knowledge areas for the AJ license. These are unweighted, non-exhaustive study suggestions rather than a formal weighted blueprint, and DLI publishes no percentage weights for them. That means you should not assume any area carries a fixed share of your 80 questions, and you should not skip an area because it looks small.
Domains 1-2: Introduction and Chapter 1 General
Definitions, scope, and the rules for how to read and apply the code. These underpin everything else.
- Know where definitions live and how they change the meaning of a rule
- Understand mandatory vs. permissive language and how exceptions modify rules
Domains 3-4: Chapter 2 Wiring and Protection; Chapter 3 Wiring Methods and Materials
The core of daily installation work: branch circuits, feeders, services, grounding, overcurrent protection, and the wiring methods and raceway fill concepts that follow.
- Branch-circuit and feeder requirements and sizing logic
- Grounding and bonding rules and where they apply
- Wiring method selection, support, and installation limits
Domain 5: Chapter 4 Equipment for General Use
Motors, transformers, lighting, appliances, and other equipment installations.
- Motor circuit conductor and protection sizing
- Transformer protection and installation rules
Domains 6-8: Chapters 5, 6, and 7
Special occupancies, special equipment, and special conditions and systems. These chapters amend or supplement the general rules, so they reward careful reading.
- Recognize when a special-occupancy rule overrides a general rule
- Pay attention to exceptions that change what is permitted in particular locations
Domain 9: Chapter 8 Communication Systems
Outside and entering-building communication systems, including how they interact with grounding and bonding.
Domain 10: Chapter 9 Tables
The tables are where many calculation questions are won or lost: conductor properties, conduit fill, and related data.
- Practice finding the right table and the right row quickly in an untabbed book
Domain 11: Applied Electrical Theory, Electrical Systems and Equipment
Ohm's law, power, single- and three-phase relationships, voltage drop, and system behavior. This area drives the calculation items.
- Voltage drop and conductor sizing under load
- Load calculations, including multifamily scenarios

Open Book Does Not Mean Easy
The AJ exam is open book, but the terms are tightly controlled. You work from a department-supplied, untabbed softcover NEC and Laws and Rules Booklet and a department-provided desk calculator. Personal reference books and electronic devices are prohibited.
The word untabbed is the one that trips people up. Many candidates train with a heavily tabbed, highlighted personal codebook and then discover on exam day that they cannot find anything quickly in a clean book. Since your passing score depends on getting at least 56 of 80 right within a five-and-a-half-hour window, navigation speed is part of your score.
Key Takeaway
Train the way you will test. Practice in an unmarked copy of the same NEC edition, rely on the table of contents and index, and use a plain desk calculator. Our practice test platform is built around this closed-navigation reality so your lookup speed is tested before the real exam.
A good drill: take a question, write down the article number you expect before opening the book, then confirm. Over time you build a mental map of where rules live, which cuts lookup time dramatically.
The September 8, 2026 Transition and Your Score Target
Your 70% target is measured against a specific NEC edition, and timing matters. DLI's dated announcement places the 2026 NEC examination transition on September 8, 2026. That is distinct from the August 17, 2026 field-code adoption date, which governs what is enforced on job sites. Do not conflate the two.
| Date | What It Governs |
|---|---|
| August 17, 2026 | Field-code adoption (what inspectors and installers apply in the field) |
| September 8, 2026 | Examination transition to the 2026 NEC |
Study materials built on the wrong edition can cost you points on article numbers, exceptions, and table references. Verify that your prep matches the edition for your test date, and see our exam dates guide for scheduling considerations.
Passing Score vs. Historical Pass Rate
Candidates frequently confuse the passing score with the pass rate. They are different things. The passing score is the 70% you must achieve. The pass rate is the share of candidates who historically succeeded.
The most recent historical journeyworker figures come from the April 14, 2026 Board of Electricity meeting minutes: 42% by total examinations and 45% by test taker, with 349 testers. Three points are essential when interpreting these numbers:
- They predate the 2026 NEC examination change and should not be presented as a pass rate for the new version.
- They are not the passing score. A 45% pass rate does not mean you need 45% to pass.
- The two figures differ because one counts every exam attempt and the other counts individual people.
If You Fall Short: Reexamination Mechanics
Missing the 70% threshold is not the end of the road, but it does cost time and money. Failed candidates must wait at least 30 days after notification before applying for reexamination, and the application or reexamination fee is $50 per attempt.
That 30-day window is best used diagnostically. After a failed attempt, reconstruct which areas felt slow or uncertain: Chapter 9 table lookups, multiple-correct items, load calculations, or special-occupancy exceptions. Then rebuild your plan around those gaps instead of simply re-reading everything. For a full cost picture across attempts, see the certification cost breakdown.
Eligibility and Fees Before You Sit
Your passing score only matters once you are approved to test. DLI requires 48 months of qualifying experience, including at least 24 months of wiring and equipment installation, subject to DLI experience-category limits. Approved two-year electrical education may provide up to 12 months of credit. Employer verification and application approval are required before you can schedule.
The experience-category limits are a common source of surprise: not every month of electrical-adjacent work counts equally, so confirm how your hours are categorized before you assume you are eligible. Our requirements guide explains how to document and qualify your experience.
After You Pass: License Term and Renewal
Once you meet the 70% requirement and receive your license, the credential is not permanent. Journeyworker licenses have two-year terms ending in the original issue month. Renewal costs $53 and requires 16 approved continuing education hours, including at least 12 NEC hours and up to four approved related hours.
