What the South Dakota Journeyman Exam Actually Is
When people search for the SD-JE exam, they are looking for the South Dakota Journeyman Electrician license examination administered under the South Dakota Electrical Commission. The exact test is ICC 531, South Dakota Journeyman Electrician, an International Code Council examination delivered through Pearson VUE. It is not a PSI exam, and it is not the electrical contractor exam (ICC 530) or the Class B exam (ICC 533). Candidates sometimes mix those up when browsing prep material, so confirm the exam number on any practice resource before you spend time with it.
The format is simple. You sit a computer-based written exam of 80 multiple-choice questions with four hours on the clock. Every item has four options and exactly one correct answer. The passing score is 70%, set by Commission rule 20:44:16:03. That works out to a comfortable time budget of three minutes per question, which matters because this is a code-lookup exam: most of your time goes to finding the right article, table or section in the 2023 NEC, not to reading the question.
If you are still working out whether you qualify to sit for it, start with our breakdown of SD-JE requirements, eligibility and prerequisites. This article focuses on what the exam covers once you are cleared to test.
The Nine Headings and the Percentage Problem
The nine content areas come from the South Dakota Contractor/Trades Examination Information Bulletin dated August 19, 2025 (printed page 7). They are headings for the examination content itself, not preparation-curriculum headings from a course provider. In order, they are:
- General Knowledge
- Services and Service Equipment
- Feeders
- Branch Circuit Conductors
- Wiring Methods and Materials
- Equipment Devices
- Control Devices
- Motors and Generators
- Special Occupancies, Equipment and Conditions
The practical consequence: do not build a study plan that skips any of the nine areas because a printed number looks small. With only 80 questions and a 70% cut, a neglected domain can cost you the exam. For more on how the scoring threshold plays out, see what you need to pass the SD-JE exam.
Domains 1-3: General Knowledge, Services, Feeders
Domain 1: General Knowledge
This is the foundation heading, and it is where Chapter 1 and Article 90 style questions tend to live: scope, definitions, and the rules that govern how every other article is applied.
- Know how to use the NEC's structure: chapters, articles, parts, tables and informative annexes, and how Chapters 5 through 7 modify the general rules.
- Be fluent in the Article 100 definitions; many questions turn on a single defined term.
- Practice basic electrical theory the way a journeyman applies it: Ohm's law, power relationships and series/parallel reasoning in practical load and voltage-drop scenarios.
- Do not dismiss this heading as "easy." It is the one most likely to be underestimated, and it supports every other domain.
Domain 2: Services and Service Equipment
Expect questions rooted in service entrance conductors, service disconnecting means, grounding and bonding at the service, and the equipment installed there.
- Service conductor sizing and the load calculation logic that feeds it.
- Grounding electrode system, grounding electrode conductor sizing and bonding requirements at the service.
- Overcurrent protection and disconnect rules for services, including number and grouping of disconnects.
- Working space and clearances around service equipment.
Domain 3: Feeders
Feeders sit between the service and the branch circuits, and they are easy to under-study because candidates lump them in with services or branch circuits.
- Feeder conductor sizing from calculated loads, including continuous and noncontinuous load treatment.
- Feeder demand factors and when each is allowed to be applied.
- Overcurrent protection for feeders and how it coordinates with conductor ampacity.
- Feeder taps and the conditions that govern them.
Domains 4-5: Branch Circuit Conductors and Wiring Methods
Domain 4: Branch Circuit Conductors
This is where ampacity tables, adjustment and correction factors, and conductor selection get tested in applied form.
- Ampacity from the allowable-ampacity tables, with temperature correction and conduit-fill adjustment applied in the right order.
- Terminal temperature limitations and how they cap the usable ampacity of a conductor.
- Branch-circuit ratings, permitted loads and required number of circuits for common occupancy types.
- Conductor identification, color conventions and permitted uses of different insulation types.
Domain 5: Wiring Methods and Materials
This heading carries the largest printed entry in the bulletin, though as noted that figure is not a validated weighting. It is also the broadest in practical terms: the NEC's wiring-method articles are long, and the questions reward knowing which article applies before you start flipping pages.
- Raceway and cable articles: permitted uses, number-of-conductor and fill limits, bending radius, support and securing intervals.
- Boxes and fittings: box fill calculations, volume allowances per conductor and device, and enclosure selection.
- Where each wiring method is permitted or restricted by location, such as damp, wet, concealed or exposed.
- Installation details: protection from physical damage, expansion fittings and underground cover requirements.
Because Domain 5 is so content-heavy, tab and highlight your NEC by article rather than by topic. If you want a compact reminder sheet to run alongside your book work, our SD-JE cheat sheet collects the must-know facts in one place.
Domains 6-7: Equipment Devices and Control Devices
Domain 6: Equipment Devices
This area covers the devices and equipment a journeyman installs on a typical job: receptacles, switches, lighting, panelboards and related equipment.
- Receptacle rating, placement and required protection, including GFCI and AFCI requirements by location.
- Panelboard rules: overcurrent protection limits, circuit directory requirements and working space.
- Luminaire installation and support, including clearances and location restrictions.
- Appliance and equipment disconnecting means and supply requirements.
Domain 7: Control Devices
Control Devices questions often connect to motor circuits and to general switching, so study them alongside Domain 8 rather than in isolation.
- Switches, contactors, relays and the distinction between a disconnecting means and a controller.
- Basic control circuit reasoning: how pilot devices, starters and overload devices relate in a motor circuit.
- Control circuit overcurrent protection and conductor requirements.
- Remote and emergency shutdown concepts where the Code requires them.
Domains 8-9: Motors and Generators, Special Occupancies
Domain 8: Motors and Generators
Motor questions are calculation-heavy and lookup-heavy at once, which makes them a place where practice speed pays off.
- Motor branch-circuit conductor sizing from full-load current tables, not nameplate current, for the conductor calculation.
- Separate motor protection types: overload, short-circuit and ground-fault, and how each is sized.
- Motor disconnecting means and controller requirements.
- Generator installation basics: overcurrent protection, grounding, and transfer equipment for standby systems.
Domain 9: Special Occupancies, Equipment and Conditions
This heading draws from the NEC's special-application chapters. These questions are usually answerable only if you know which article governs the situation described.
- Hazardous (classified) locations: how the classification system works and the wiring-method consequences.
- Health care, assembly, agricultural and similar occupancy-specific rules.
- Special equipment such as signs, pools and fountains, and other articles with their own grounding and bonding rules.
- Emergency systems, standby systems and similar conditions with distinct installation requirements.
Reference Books: What Counts and What Is Merely Permitted
This is an area where candidates get tripped up, so the distinction is worth stating carefully. The exam-specific reference listing names two sources: the 2023 NEC and Ugly's Electrical References, any edition. The Commission began administering 2023 NEC examinations on December 2, 2024, so make sure the code book you study from is the 2023 edition, not an earlier cycle.
Separately, the bulletin's general reference policy permits additional aids: the NEC Handbook, Ferm's Fast Finder Index, and Tom Henry's Key Word Index. These permissions come from the general policy, not the exam-specific source list, so check the current bulletin and your testing confirmation for exactly what you may bring before test day. Do not assume a tabbed, annotated or third-party study edition is allowed.
| Reference | Where it appears in the bulletin |
|---|---|
| 2023 NEC | Exam-specific reference box |
| Ugly's Electrical References (any edition) | Exam-specific reference box |
| NEC Handbook | General reference policy |
| Ferm's Fast Finder Index | General reference policy |
| Tom Henry's Key Word Index | General reference policy |
Sequencing the Nine Areas Over Eight Weeks
You do not need a generic study system here; you need an order that respects how the domains depend on each other. Start with the definitions and structure that everything else relies on, then follow the path electricity takes through an installation: service, feeder, branch circuit, then devices and loads. Save the special-application material for later, when your code-book navigation is fast.
General Knowledge
- Article 90, Article 100 definitions, and NEC layout
- Theory and calculation fundamentals
Services and Service Equipment
- Service conductors, disconnects, grounding and bonding
Feeders and Branch Circuit Conductors
- Load calculations feeding feeder sizing
- Ampacity tables, correction and adjustment factors
Wiring Methods and Materials
- Raceway and cable articles, box fill, support and protection
- Two weeks because the material is broad
Equipment Devices and Control Devices
- Receptacles, panelboards, luminaires, switches and controllers
Motors and Generators; Special Occupancies
- Motor circuit calculations first, then classified locations and special articles
Timed mixed review
- Full-length timed practice using your actual reference books
- Revisit the domains where you were slowest, not just least accurate
For a broader plan built around first-attempt success, see our SD-JE study guide, and when you are ready to test your recall, the practice test offers original questions written in the exam's multiple-choice style. They are not copies of live exam items. If you are wondering how demanding the test really is, read how hard the SD-JE exam is.
Fees, Approval Window and Retake Rules
The order of operations matters. You apply to the Commission first; only after approval can you schedule with Pearson VUE, and you must test within 90 days of approval. Don't apply until your study plan is far enough along to meet that window.
| Charge | Amount |
|---|---|
| Examination fee | $115 |
| State application | $60 |
| Initial journeyman license | $80 |
| Biennial journeyman renewal | $80 |
These are separate charges, so budget for all of them rather than just the exam fee. Our SD-JE certification cost breakdown walks through each one.
Under Commission rule 20:44:16:03, if you fail you must wait 30 days after the first failure before retesting, and 90 days after a failed reexamination. After you pass, license issuance must be completed within 90 days of the passing notification. For scheduling details, see SD-JE exam dates and deadlines.
Standard eligibility 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 education or military credits under ARSD 20:44:16:09 can apply conditionally, but they are not blanket reductions for any schooling or service, and unlicensed work hours do not count. Licenses expire June 30 of even-numbered years, and renewal requires 16 approved continuing-education hours, at least eight of them code hours, with no more than eight approved online hours.
Key Takeaway
Study all nine headings, build your plan around the 2023 NEC and the aids you are actually allowed to use, and schedule only after your approval so the 90-day window works for you, not against you.
