- The South Dakota Journeyman Electrician exam (ICC 531) requires a 70% to pass, set by Commission rule 20:44:16:03.
- The exam has 80 multiple-choice questions, four options each, and a four-hour time limit.
- After a first failure you wait 30 days; after a failed reexamination, 90 days.
- Test within 90 days of Commission approval; Pearson VUE scheduling comes after approval.
The Number: 70% on an 80-Question Exam
If you are preparing for the South Dakota Journeyman Electrician license exam, the passing standard is simple to state: 70%. The exam is officially identified as ICC 531, South Dakota Journeyman Electrician, an International Code Council examination delivered through Pearson VUE (not PSI). It is a computer-based written test with 80 multiple-choice questions, a four-hour time limit, and four answer options per item with exactly one correct choice.
This article is specifically about that exam: the one required by the South Dakota Electrical Commission for journeyman licensure. It is not the electrical contractor exam (530) or the Class B exam (533), and nothing here should be read as applying to those.
What 70% Means in Practice
Seventy percent on an 80-question exam works out to roughly 56 correct answers. We state that as an approximation because the Commission and ICC publish the 70% standard, and candidates should treat the raw-number conversion as a planning figure rather than a published cut score. What matters strategically is this: you can miss about a quarter of the questions and still pass.
That tolerance changes how you should study. A journeyman candidate who has spent years in the field often feels strongest on installation practice and weakest on code navigation. Because every question is a four-option, single-answer item, the exam rewards two skills in particular:
- Fast, accurate code lookup. Many questions are answerable only by finding the right article, table, or exception in the 2023 NEC. Knowing where things live saves minutes per question.
- Careful reading of conditions. Distractors are typically plausible values from a nearby table or a neighboring rule. Reading the occupancy, voltage, conductor material, and installation method before you open the book prevents costly mismatches.
Four hours across 80 questions gives you an average of three minutes per item. That is generous for recall questions and tight for multi-step calculations that require table lookups, so pacing matters. If you want a candid read on how demanding the exam is overall, see our guide on how hard the SD-JE exam is.
Who Sets the Pass Mark and Where It Is Written
The pass mark is not an ICC marketing figure or a testing-vendor preference. It comes from the state. Commission rule 20:44:16:03 sets the 70% passing score and also governs the waiting periods after a failure and the timeline for completing license issuance after you are notified that you passed. The Commission's Wiring Bulletin reproduces the examination, qualification, fee, and renewal rules in one document, and the Commission's exam-policy page summarizes the process.
Here is how the roles divide, which is worth understanding before you schedule anything:
| Body | Role in the Process |
|---|---|
| South Dakota Electrical Commission | Sets eligibility, approves your application, sets the 70% pass mark and retake waits, issues the license |
| International Code Council (ICC) | Develops and owns the ICC 531 examination content |
| Pearson VUE | Delivers the computer-based exam and handles scheduling after Commission approval |
Because the score standard lives in state rule, you should always confirm current details against the Commission's own pages before test day. Our SD-JE requirements guide walks through eligibility and documentation in detail.
Passing Score Is Not a Pass Rate
Candidates frequently conflate two different questions: "What score do I need?" and "What share of people pass?" The first has a clear answer (70%). The second does not have a verified answer that we can responsibly publish. We have not verified any official cohort pass-rate statistics for this exam, so we do not quote one. Anyone who offers a precise pass percentage without citing the Commission or ICC should be treated skeptically.
The distinction matters because the passing score is a fixed requirement you control by preparing, while a pass rate is a population statistic that tells you little about your own readiness. For a measured discussion of what is and is not known, read our article on the SD-JE pass rate.
The Nine Content Areas Behind Your Score
Your 70% is earned across nine official content headings drawn from the South Dakota Contractor/Trades Examination Information Bulletin (August 19, 2025). Every one of them is fair game, so a sound plan covers all nine. The areas are:
1. General Knowledge
The foundation layer that supports every other area.
- Definitions, terminology, and scope from the NEC's early articles
- Basic electrical theory and calculation fluency
- Safety fundamentals and how to navigate the code book efficiently
2. Services and Service Equipment
Where the utility connection meets the building.
- Service conductors, service-entrance sizing, and disconnecting means
- Grounding and bonding at the service
- Overcurrent protection and metering arrangements
3. Feeders
Distribution between the service and downstream panels.
- Feeder sizing and demand-load considerations
- Overcurrent protection and conductor ampacity
- Separately derived systems and feeder grounding
4. Branch Circuit Conductors
The circuits that reach receptacles, lighting, and equipment.
- Ampacity, derating, and temperature correction
- Branch-circuit ratings, loads, and required circuits
- Voltage drop considerations and conductor selection
5. Wiring Methods and Materials
Raceways, cables, boxes, and fittings.
- Selecting and installing the correct wiring method for the environment
- Box fill, conduit fill, support, and protection requirements
- Conductor identification, splices, and terminations
6. Equipment Devices
The hardware that connects loads to the system.
- Receptacles, switches, and device ratings
- Luminaires, appliances, and equipment connections
- GFCI and AFCI protection requirements
7. Control Devices
The means of switching, starting, and managing loads.
- Controllers, switches, and disconnecting means
- Control circuits and overload protection concepts
- Coordination between control gear and the equipment it serves
8. Motors and Generators
A calculation-heavy area that rewards table fluency.
- Motor branch-circuit conductor and protective-device sizing
- Overload protection and motor control basics
- Generator installation, transfer equipment, and related requirements
9. Special Occupancies, Equipment and Conditions
The Chapter 5 through 8 territory where context changes the answer.
- Hazardous (classified) locations and other special occupancies
- Special equipment and special conditions with modified rules
- Recognizing when a general rule is amended by a special-purpose article

The Bulletin Table Quirk: Why We Omit Percentages
Here is something most prep sites gloss over. The official bulletin includes a table of the nine content headings with a column labeled "percentage." When you add up the printed entries (5%, 9%, 3%, 15%, 21%, 10%, 3%, 5%, 9% in Domain 1 through 9 order), they total only 80%, not 100%. The source does not explain the gap.
We handle that honestly rather than papering over it. We do not renormalize the numbers to force them to 100%, we do not relabel them as question counts, and we do not guess at a missing 20% topic. As a result, you will notice that the domain descriptions above carry no percentages. The only safe reading is a loose one: Wiring Methods and Materials carries the largest printed entry (21%), which suggests it deserves generous study time, but that figure is not a validated weighting allocation.
Key Takeaway
Treat all nine areas as testable. Give extra time to Wiring Methods and Materials because of its large printed entry, but do not skip small-looking areas like Feeders or General Knowledge. With only about a quarter of the exam as your margin for error, a weak area you ignored can sink an otherwise strong score.
References You Can Use While Testing
Because the exam draws on code lookup, the reference policy affects your score as much as your knowledge does. The bulletin lists exam-specific source books, and it separately describes a general reference policy. Keep the two ideas distinct:
| Category | What Is Listed |
|---|---|
| Exam-specific reference box | 2023 NEC; Ugly's Electrical References (any edition) |
| General reference policy (separately permitted) | NEC Handbook; Ferm's Fast Finder Index; Tom Henry's Key Word Index |
The Commission began administering 2023 NEC examinations on December 2, 2024, so you should study from the 2023 edition, not an older one. Tabbing, highlighting where permitted, and practicing with the index tools you intend to bring will make a measurable difference in how many of your four hours you spend hunting for answers. Always verify the current reference rules on the Commission's exam page and in the candidate bulletin before test day, since policies about what you may bring into the testing room are set by the state and the test center.
If You Miss the Mark: Waiting Periods
Falling short of 70% is not the end of the road, but the rules impose real delays, so it is worth knowing them in advance. Under Commission rule 20:44:16:03:
- After your first failure, you must wait 30 days before retesting.
- After a failed reexamination, the wait increases to 90 days.
Those waits are failure-dependent, meaning they apply based on your attempt history, not as a blanket rule for everyone. The practical lesson: treat your first sitting as a real attempt. Passing on the first try keeps your license timeline intact and avoids the compounding delay. Our first-attempt study guide outlines how to prepare so that a retake never becomes necessary.
Fees, Approval Window, and License Timing
Your score is only one gate. The process also has a sequence and several distinct charges that candidates sometimes blur together. Keep them separate:
| Charge | Amount |
|---|---|
| Exam fee | $115 |
| State application | $60 |
| Initial journeyman license | $80 |
| Biennial journeyman renewal | $80 |
The sequence matters. The Commission approves your application first, and only then do you schedule through Pearson VUE. Once approved, you must test within 90 days. After you receive notice that you passed, license issuance must be completed within 90 days under the same rule. Miss either window and you may find yourself repeating steps, so schedule deliberately. For the full pricing picture, see our certification cost breakdown, and for scheduling logistics see our guide to exam dates and testing windows.
Eligibility itself is not about your score. The standard path is four years and 8,000 hours as a licensed apprentice working under qualifying licensed electrical-contractor supervision, documented through employer experience affidavits. Specified Class B supervision and certain education or military credits can count under ARSD 20:44:16:09, but those are conditional credits, not blanket reductions, and unlicensed work hours do not count.
A Score-Driven Study Plan
Since 70% is the target and the nine areas are all testable, build your plan around closing gaps rather than polishing strengths. One practical sequencing, assuming a roughly six-week runway before your approved testing window:
Foundations and Services
- General Knowledge: definitions, code navigation, and the calculation basics everything else uses
- Services and Service Equipment, then Feeders, since both build on the same sizing logic
The Heavy Middle
- Branch Circuit Conductors and Wiring Methods and Materials, given the latter's large printed entry
- Equipment Devices and Control Devices, tying hardware to the rules that govern it
Calculations, Specials, and Full Runs
- Motors and Generators table work; Special Occupancies, Equipment and Conditions with attention to how special rules modify general ones
- Timed practice runs mirroring 80 questions in four hours, then targeted review of misses
Use original practice questions that test the 2023 NEC rather than memorizing leaked or claimed live items; the goal is code fluency, not recall of specific questions. You can drill every area with our SD-JE practice test platform, and our one-page cheat sheet is useful for final-week review. If you are weighing the investment, our analysis of whether the certification is worth it and the salary guide treat earnings as a research topic rather than a guarantee.
