- SD-JE here means the South Dakota Journeyman Electrician exam, ICC 531, issued through the South Dakota Electrical Commission.
- The test is 80 multiple-choice questions in four hours, and you need 70% to pass.
- Commission approval comes first; you must then test through Pearson VUE within 90 days.
- Budget $115 exam fee, $60 application and $80 initial license as three separate charges.
What the SD-JE Credential Actually Is
Several unrelated credentials share the letters "SD-JE." On this site, the term refers to exactly one thing: the South Dakota Journeyman Electrician License Exam, the written examination a candidate must pass to earn a journeyman electrician license from the South Dakota Electrical Commission. The exam itself is designated ICC 531, South Dakota Journeyman Electrician. It is an International Code Council examination, and it is delivered by Pearson VUE, not PSI.
That distinction matters for practical reasons. The credential is a state license rather than a voluntary industry certificate, so passing the exam is one gate among several. You also need documented work experience, an approved application and a paid license. If you want the broader background on the name and what it covers, see our explainers on what SD-JE is and what SD-JE stands for.
Be careful with search results here. The Commission's examinations for electrical contractors (exam 530) and Class B electricians (exam 533) are different tests with different scopes. Everything in this article applies to the journeyman exam only.
ICC 531 Format: Questions, Time and Passing Score
The journeyman exam is a computer-based written test with a simple structure:
| Feature | ICC 531 Detail |
|---|---|
| Delivery | Computer-based, administered by Pearson VUE |
| Number of questions | 80 multiple-choice |
| Answer options | Four choices, one correct answer |
| Time allowed | Four hours |
| Passing score | 70% (Commission rule 20:44:16:03) |
| Code basis | 2023 NEC (examinations on this edition began December 2, 2024) |
Four hours for 80 questions gives you three minutes per item on average. That sounds generous, and for pure recall questions it is. The pressure comes from code-lookup questions, where you must find the right article, table or exception in a large book. A candidate who has never practiced navigating the NEC under time pressure can burn ten minutes on a single question about conductor fill or demand loads.
A 70% passing score on 80 questions is a percentage-based threshold. Do not confuse it with a pass rate, which would describe how many candidates succeed. We have not verified any official cohort pass-rate statistics, so we do not quote any. For a deeper look at the threshold itself, read our guide to the SD-JE passing score, and for an honest take on difficulty, see how hard the SD-JE exam is.
From Apprentice Hours to Approval to Pearson VUE
You cannot simply book a seat. The sequence in South Dakota runs through the Commission first, and the order is rigid.
Step 1: Meet the experience requirement
Standard eligibility is four years and 8,000 hours as a licensed apprentice working under qualifying licensed electrical-contractor supervision. Your hours are documented through employer experience affidavits. Two details trip people up:
- Unlicensed work does not count. Hours logged before you held an apprentice license are not credited toward the requirement.
- Education and military credits are conditional. The rules (ARSD 20:44:16:09) recognize specified Class B supervision and certain education or military credits, but these are targeted credits, not blanket reductions for any schooling or service. Check how your specific background maps to the rule before assuming it shortens your timeline.
Our SD-JE requirements guide walks through eligibility in more detail.
Step 2: Apply and get approval
You submit the Electrician License Application (revised October 2025) along with the required fees. The Commission reviews your qualifications and approves you to test. Approval precedes scheduling. Pearson VUE will not seat you until the Commission has cleared you.
Step 3: Schedule within 90 days
Once approved, you have 90 days to test. This is a real deadline, not a suggestion. Candidates who delay scheduling because they feel underprepared risk letting the approval window lapse. Plan your study calendar around the approval date, not the other way around. Our page on SD-JE exam dates and scheduling covers the logistics.
Key Takeaway
Do the bulk of your studying before you apply, or at minimum before approval arrives. The 90-day clock starts running when you are approved, and a rushed final month is the most common way to waste a $115 exam attempt.
Where Your Money Goes: Test, Application and License
South Dakota separates its charges, which means the headline exam fee is not your total cost. Here is how the pieces break down:
| Charge | Amount | What it covers |
|---|---|---|
| Examination fee | $115 | The ICC 531 test itself |
| State application | $60 | Commission review of your application |
| Initial journeyman license | $80 | Issuing the license after you pass |
| Biennial renewal | $80 | Renewing the license every two years |
Adding the first three gives a baseline of $255 to go from application to an issued license, assuming you pass on the first attempt. A retake means paying the exam fee again. Study materials, code books and any prep course are on top of that. For the full picture, see the SD-JE certification cost breakdown.
Whether the licensing investment pays off depends on your career plans. We deliberately avoid quoting salary numbers because we have not verified an official wage figure. If you are weighing the decision, our ROI analysis and salary guide frame the questions to ask rather than promising an earnings result.
The Nine Content Areas You Need to Study
The exam content is organized under nine headings taken from the Contractor/Trades Examination Information Bulletin dated August 19, 2025. Each one deserves a place in your plan.
1. General Knowledge
The foundation layer: definitions, code organization, and the rules for how the NEC itself is applied.
- Know Article 100 definitions cold, because they decide how every other rule is read
- Understand how Chapters 1 through 4 apply generally while Chapters 5 through 7 modify them
- Practice electrical theory basics: Ohm's law, power, series and parallel relationships
2. Services and Service Equipment
Where utility power enters the building and how it is controlled and protected.
- Service conductor sizing and service load calculations
- Grounding and bonding at the service
- Disconnecting means, overcurrent protection and metering equipment requirements
3. Feeders
The conductors between the service and the branch-circuit panels or equipment they supply.
- Feeder sizing, demand factors and load calculations
- Overcurrent protection and conductor ampacity adjustments
- Grounding and bonding for separate buildings and subpanels
4. Branch Circuit Conductors
Circuit sizing, protection and the rules that govern what each circuit can serve.
- Ampacity, correction and adjustment factors
- Continuous versus noncontinuous load treatment
- Voltage drop considerations and required branch-circuit ratings
5. Wiring Methods and Materials
The largest printed entry in the bulletin's table, covering the raceways, cables, boxes and fittings used in installations.
- Raceway and cable types, permitted uses and support requirements
- Box fill calculations and conductor fill in conduit and tubing
- Installation rules for wet, damp, dry and corrosive locations
6. Equipment Devices
Receptacles, switches, luminaires and the devices that connect to the wiring system.
- Receptacle placement, ratings and tamper-resistant and GFCI/AFCI requirements
- Luminaire and lighting equipment installation rules
- Appliance and utilization equipment connection requirements
7. Control Devices
The components that start, stop, protect and regulate circuits and equipment.
- Switches, controllers and disconnecting means
- Overcurrent and overload protective devices
- Basic control circuit concepts as they relate to code requirements
8. Motors and Generators
Motor circuits are a classic source of tricky calculation questions.
- Motor branch-circuit conductor sizing from full-load current tables
- Overload, short-circuit and ground-fault protection for motors
- Generator installation, transfer equipment and related requirements
9. Special Occupancies, Equipment and Conditions
The chapters that modify the general rules for particular settings and equipment.
- Hazardous (classified) locations, healthcare and assembly occupancies
- Swimming pools, signs, solar and other specialized installations
- Specific rules that override or supplement Chapters 1 through 4
For a deeper treatment of each area, our complete guide to all nine SD-JE content areas expands on the topics above.
The Printed Percentage Problem
Most exam-prep articles would now present a tidy weighting chart and tell you to allocate study time accordingly. We cannot do that honestly, and you should be skeptical of anyone who does.
The official bulletin does print a column labeled "percentage" next to the nine content headings. In Domain 1 through 9 order, the printed entries are 5%, 9%, 3%, 15%, 21%, 10%, 3%, 5% and 9%. Add them up and you get only 80%, not 100%. The source does not explain the gap.
The practical consequence is straightforward: study all nine areas. Do not skip Feeders, Motors and Generators or General Knowledge because they show smaller printed numbers. When a table cannot be reconciled, the safe strategy is full coverage with extra time on the areas where you are personally weakest. Our SD-JE study guide builds on this full-coverage approach.
Reference Books: Exam-Listed vs. Generally Permitted
Search interest around "open book" is high, so precision helps here. The exam is not a free-for-all where any book is allowed. There are two distinct layers of reference permission in the bulletin:
| Category | Materials |
|---|---|
| Exam-specific reference box (listed for ICC 531) | 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 two lists are not the same. The 2023 NEC and Ugly's are the books named in the exam-specific box. The NEC Handbook, Ferm's Fast Finder and Tom Henry's Key Word Index come from the bulletin's general reference policy. Before test day, confirm the current rules at the Pearson VUE and Commission sources, including what format a book can be in and whether tabs or annotations are permitted.
The bigger point is this: having a book in the room does not help if you cannot use it quickly. Index-based lookup is a skill. Practice finding answers by keyword, by article and by table, and time yourself. Candidates who treat "open book" as a substitute for knowledge usually run short of time.
A Domain-Ordered Study Sequence
Rather than a generic calendar, order your study around how the content builds. The logic is that later domains assume you already understand earlier ones. This sample sequence runs eight weeks; stretch or compress it to fit your approval window.
General Knowledge and code navigation
- Learn how the 2023 NEC is organized and how to search it quickly
- Memorize key Article 100 definitions
- Tab your book and practice looking up topics against a timer
Services, Feeders and Branch Circuit Conductors
- Work service, feeder and branch-circuit load calculations until the steps are automatic
- Practice ampacity corrections, adjustment factors and overcurrent protection selection
- Review grounding and bonding as it applies at each level
Wiring Methods and Materials plus Equipment Devices
- Spend extra time here, since this area carries the largest printed entry
- Drill box fill and conduit fill calculations
- Learn permitted uses by location type for each wiring method
Control Devices and Motors and Generators
- Practice motor circuit sizing using the full-load current tables
- Review protection requirements for motors and generator installations
Special Occupancies, Equipment and Conditions
- Study hazardous locations, healthcare, pools and other special topics
- Focus on how these chapters modify the general rules
Full-length timed practice
- Take 80-question practice sets under a four-hour limit
- Review every miss by finding the exact code section
If you want realistic reps, our SD-JE practice test offers original questions in the exam's multiple-choice style. All practice items are written fresh; none are claimed copies of live exam content. For fast review in the final days, the SD-JE cheat sheet condenses must-know facts.
If You Fail: Waiting Periods and Deadlines
Commission rule 20:44:16:03 sets out what happens if you do not pass, and the waits are not interchangeable:
- After a first failure: you must wait 30 days before retesting.
- After a failed reexamination: the wait extends to 90 days.
The retake wait is a built-in study period, so use it deliberately. Pull your score report, identify which of the nine content areas gave you trouble, and rebuild those areas rather than rereading everything. Also keep an eye on your approval window; confirm with the Commission how a retake interacts with your original 90-day testing deadline so you are not caught off guard.
After You Pass: Licensing and Renewal
Passing the exam is not the finish line. The rule also requires that license issuance be completed within 90 days after your passing notification, so pay the $80 initial license fee and finish any remaining paperwork promptly.
Once you are licensed, renewal follows a fixed rhythm:
- Licenses expire June 30 of even-numbered years.
- Renewal requires 16 approved continuing-education hours.
- At least eight of those hours must be code hours.
- No more than eight hours may be approved online courses.
- The biennial renewal fee is $80.
The online cap is the detail that catches people. If you plan to complete all 16 hours from your couch the week before June 30, you will find that half must come from another format. Spread your hours across the two-year cycle and verify course approval before enrolling.

Frequently Asked Questions
Yes. On this site, SD-JE means the South Dakota Journeyman Electrician License Exam, which is ICC 531. It is an International Code Council exam delivered by Pearson VUE. It is not the electrical contractor exam (530) or the Class B exam (533).
The exam has 80 multiple-choice questions, each with four options and one correct answer, and you have four hours. The passing score is 70%, set by Commission rule 20:44:16:03.
The charges are separate: a $115 exam fee, a $60 state application fee and an $80 initial journeyman license fee. Renewal is $80 every two years. Study materials and any retakes are additional. See our full cost breakdown for details.
The Commission must approve you before you can schedule with Pearson VUE, and you must then test within 90 days of that approval. Plan your preparation around that window.
The exam-specific reference box lists the 2023 NEC and Ugly's Electrical References (any edition). The bulletin's general policy separately permits the NEC Handbook, Ferm's Fast Finder Index and Tom Henry's Key Word Index. Confirm current rules with the Commission and Pearson VUE before test day, and practice fast lookups so the books actually help.
