- The Texas journeyman exam is two separate computer-based portions, NEC Knowledge and Calculations, each needing 70% on its own timer.
- TDLR Fiscal Year 2025 reported 24.46% for Journeyman NEC and 20.56% for Calculations; these are attempt-level figures, not a license probability.
- NEC Knowledge has 56 scored items in 130 minutes; Calculations has 24 scored items in 110 minutes.
- Only permanent index tabs made by the NEC publisher are allowed; NEC Handbooks and loose-leaf, spiral, or ring-bound copies are prohibited.
What "Hard" Actually Means for This Exam
People ask how hard the Texas Journeyman Electrician License Exam (TX-JE) is, and the honest answer has several layers. The exam is open-book, which sounds forgiving. But open-book does not mean easy. It means the test measures whether you can locate, interpret, and apply the correct NEC provision under time pressure, not whether you can recite it from memory.
Difficulty on this exam comes from four sources: a two-portion structure where each portion must be passed separately, a code book that is dense and heavily cross-referenced, calculation questions that punish a single wrong step, and a tested edition that is changing in 2026. This guide breaks down each one so you can judge where you personally are most exposed. If you want the full domain-by-domain breakdown, see our TX-JE Exam Domains 2026: Complete Guide to All 20 Content Areas.
Two Portions, Two Timers, Two Pass Marks
Since March 11, 2025, the Journeyman route has been delivered as two written portions. Both are computer-based multiple-choice. The calculations portion is not a hands-on practical assessment; it is multiple-choice questions that require you to work problems on the supplied electronic notepad and calculator.
| Feature | NEC Knowledge | Calculations |
|---|---|---|
| Total questions | 59 (3 unscored) | 26 (2 unscored) |
| Scored questions | 56 | 24 |
| Time allowed | 130 minutes | 110 minutes |
| Passing requirement | 70% | 70% |
| Format | Computer-based multiple choice | Computer-based multiple choice |
Three structural details raise the effective difficulty:
- Each portion has its own timer. Unused time on one portion does not roll over to the other.
- Each portion has its own passing requirement. Strength in one does not offset weakness in the other.
- No required order is published. You should not assume one portion is a warm-up for the other.
The time per scored item is generous on the Knowledge side and tighter on Calculations. Because you have 110 minutes for 24 scored questions on Calculations, the time pressure is less about speed and more about avoiding a rushed arithmetic or table-selection error. For the exact scoring mechanics, our TX-JE Passing Score 2026: Exactly What You Need to Pass article goes deeper.
What the FY2025 TDLR Statistics Show (and Don't)
TDLR publishes electrician exam statistics by fiscal year. For Fiscal Year 2025, the Journeyman rows read as follows:
| FY2025 Journeyman Row | Passes / Attempts | Reported Rate |
|---|---|---|
| Journeyman NEC | 1,402 / 5,731 | 24.46% |
| Journeyman Calculations | 1,301 / 6,328 | 20.56% |
| Separate unsplit Journeyman row | 1,390 / 5,050 | 27.52% |
These figures are real, but they are easy to misread. Please keep these limits in mind:
- They are attempt-level counts, not unique first-time candidates. Someone who fails and retakes appears more than once.
- They are distinct historical cohorts. The unsplit row reflects a different assessment structure and should not be blended with the two component rows.
- They are not a combined-license passing probability. Do not multiply the two component rates to estimate your odds; the cohorts are not independent or comparable that way.
- They are not results for the 2026 NEC examination. They describe fiscal year 2025 only.
Where the NEC Knowledge Portion Gets Difficult
The Knowledge portion maps to ten content headings (Domains 1 through 10 in our numbering). The published scored-item allocations total 56. Those are item counts, not official percentage weights, and it is worth knowing where the items concentrate.
| Domain | Topic Area | Scored Items |
|---|---|---|
| Domain 1 | Definitions, Theory, and Plans | 3 |
| Domain 2 | Electrical Services, Service Equipment, and Separately Derived Systems | 6 |
| Domain 3 | Electrical Feeders | 3 |
| Domain 4 | Branch Circuits and Conductors | 10 |
| Domain 5 | Electrical Wiring Methods and Electrical Materials | 10 |
| Domain 6 | Electrical Equipment and Devices | 10 |
| Domain 7 | Motors and Generators | 5 |
| Domain 8 | Electrical Control Devices and Disconnecting Means | 1 |
| Domain 9 | Special Occupancies, Equipment, and Conditions | 6 |
| Domain 10 | Renewable Energy Technologies | 2 |
The heavy middle: Domains 4, 5, and 6
Three domains carry ten scored items each, so together they account for 30 of the 56 scored Knowledge items. That is the core of the portion, and it is where the exam gets hard in a practical sense.
Domain 4: Branch Circuits and Conductors (10 items)
This area spans GFCI and AFCI protection, branch circuits, branch-circuit overcurrent protection, conductors, and grounding and bonding conductors.
- Know which locations require GFCI and which require AFCI, and read the exact wording of each requirement.
- Practice finding conductor ampacity and overcurrent rules quickly in the book.
- Separate grounding conductor questions from bonding conductor questions; the exam treats them as distinct.
Domain 5: Electrical Wiring Methods and Electrical Materials (10 items)
This covers raceways and cable trays, boxes and enclosures, cabinets and panels, cables and cords, and underground wiring.
- Expect questions that hinge on a single permitted-or-prohibited use clause.
- Know where fill, support, and burial-depth rules live so you can verify rather than guess.
Domain 6: Electrical Equipment and Devices (10 items)
This covers receptacles and switches, luminaires, air-conditioning, refrigeration and heating equipment, appliances, and workspace clearance.
- Workspace clearance is a classic area where candidates misremember dimensions; look them up every time.
- HVAC equipment rules overlap with motors, so watch for questions that blend articles.
The small domains still matter
Domain 8 (control devices and disconnecting means) carries only one scored item, and Domain 10 (renewable energy technologies, including photovoltaics and electrical vehicle chargers) carries two. It is tempting to skip them. But on a 56-item portion where you need 70%, every item is worth roughly the same, and unfamiliar article layouts in newer topics like photovoltaics and EV charging cost time if you meet them cold on test day.
Why the Calculations Portion Trips People Up
The Calculations portion has its own ten headings (Domains 11 through 20), with 24 scored items total. Names repeat from the Knowledge side, but these are distinct portion-specific rows. Do not treat "Electrical Feeders" in Knowledge and "Electrical Feeders" in Calculations as the same bucket.
| Domain | Topic Area | Scored Items |
|---|---|---|
| Domain 11 | Calculations and Theory | 2 |
| Domain 12 | Electrical Services, Service Equipment, and Separately Derived Systems | 4 |
| Domain 13 | Electrical Feeders | 3 |
| Domain 14 | Branch Circuit Calculations and Conductors | 4 |
| Domain 15 | Electrical Wiring Methods and Electrical Materials | 2 |
| Domain 16 | Electrical Equipment and Devices | 2 |
| Domain 17 | Motors and Generators | 2 |
| Domain 18 | Electrical Control Devices and Disconnecting Means | 1 |
| Domain 19 | Special Occupancies, Equipment, and Conditions | 3 |
| Domain 20 | Renewable Energy Technologies | 1 |
Why 24 items is less forgiving than it looks
At 70%, you need roughly 17 of 24 scored items correct. With so few scored questions, three or four misses from a single weak topic can decide the outcome. The largest allocations are Domain 12 (service and separately derived system calculations) and Domain 14 (branch-circuit calculations), at four items each. Those two areas alone represent a third of the scored items, so a weak spot in service load calculations or conductor sizing is hard to recover from.
The assumptions that cost points
- Copper is assumed unless the question directs otherwise. Do not reach for aluminum values without a prompt.
- Exceptions and optional calculation methods apply only when the question directs you to use them. Applying an optional method uninvited can produce a different answer than the one keyed.
- Multi-step problems compound errors. One wrong table lookup early in a service or feeder calculation carries through every later step.
The calculator rules matter here too: only a silent, battery-powered, nonprogrammable calculator without an alphabetic keyboard or paper printing is allowed. If your usual calculator has programmable memory or a QWERTY-style keyboard, replace it well before test day and practice on the permitted type. Our TX-JE Cheat Sheet 2026: One-Page Review of Must-Know Facts is a good companion for the formulas and rules you will use most.
The 2026 NEC Transition Adds a Version Problem
The tested reference is NFPA 70, the 2026 National Electrical Code, effective September 1, 2026, according to an explicit dated notice in the currently linked bulletin. That creates a genuine difficulty that did not exist in a stable-edition year: candidates can be unsure which edition to buy, which edition their older notes describe, and which edition the questions follow.
One more trap: the current text permits any soft-bound NEC edition into the room, but questions reference the designated tested edition. Being allowed to carry an older book is not proof that older-edition answers are tested. Also, older TDLR-hosted material, including a bulletin updated March 30, 2023 that still shows up in searches, is superseded for this route. Its old combined examination description and reference list must not override the current linked bulletin.
The Open-Book Rules Candidates Underestimate
Because the exam is open-book, preparation of the physical book is part of the preparation itself, and the rules are strict.
| Item | Allowed or Prohibited |
|---|---|
| Soft-bound NEC | Allowed |
| NEC Handbook | Prohibited |
| Loose-leaf, spiral-bound, or ring-bound copy | Prohibited |
| Existing notes, highlighting, underlining | Allowed |
| Permanent index tabs manufactured/provided by the NEC publisher | Allowed |
| Homemade, DIY, or non-NEC tabs | Not authorized |
| Added paper or writing/marking in the book during the exam | Prohibited |
| Electronic notepad | Supplied |
The practical consequence: do your annotation and tabbing at home, using only publisher-made permanent tabs. A book full of sticky flags or hand-labeled tabs is a problem you do not want to discover at the check-in desk. Then practice navigating the book using your tabs under timed conditions, because a well-tabbed book you cannot navigate quickly is only marginally better than an untabbed one.
The Other Hurdle: 7,000 Hours, 8,000 Hours, and the One-Year Clock
Many people searching "how hard is the exam" are really asking how hard the whole path is. Eligibility and licensure are separate steps with different hour thresholds:
- TDLR may approve early testing at 7,000 verified qualifying on-the-job hours under a Texas-licensed Master Electrician.
- License issuance requires 8,000 approved hours, supervisory verification, the application, and background review.
- Each supervising Master Electrician must verify the applicable experience.
- All requirements must be completed within one year after TDLR receives the application.
That one-year window is a quiet source of difficulty. Attempts are unlimited within the eligibility period, but each retake of one or both portions costs USD 78, and the separate initial TDLR application fee is USD 30. A scattershot approach that burns through multiple retakes costs real money and calendar time. See our TX-JE Requirements 2026: Eligibility, Prerequisites & How to Qualify and TX-JE Certification Cost 2026: Complete Pricing Breakdown articles for the full process and fee picture.
Key Takeaway
The fee is USD 78 for both portions, and a retake of one or both is also USD 78, not USD 39 per portion. If you are confident in one portion and shaky on the other, the economics favor spending extra prep time on the weak one before scheduling rather than testing early and paying again.
A Domain-Ordered Prep Plan
Generic study advice is everywhere; what matters here is sequencing by where the scored items sit. This plan assumes roughly six weeks and a tabbed NEC in hand. Adjust the length to your own timeline, and see the full TX-JE Study Guide 2026: How to Pass on Your First Attempt for more detail.
Book setup and Domains 1 to 3
- Buy the book edition confirmed against the current bulletin and apply only publisher-made permanent tabs.
- Work through definitions, theory, plan reading, services, and feeders so you learn the book's layout early.
The ten-item domains (4, 5, 6)
- Spend the most reading time here: branch circuits and conductors, wiring methods and materials, equipment and devices.
- Drill GFCI/AFCI locations, raceway and box rules, and workspace clearance until you can find each in under a minute.
Domains 7 to 10
- Cover motors and generators, control devices and disconnects, special occupancies, and renewable energy topics including photovoltaics and EV chargers.
Calculations: Domains 11 to 14
- Concentrate on service, separately derived system, feeder, and branch-circuit calculations; these hold the largest Calculations allocations.
- Practice on a permitted calculator and write out every step.
Calculations: Domains 15 to 20, plus timed review
- Finish the remaining calculation areas, then run timed sessions for each portion separately, honoring each portion's own clock.
Whatever practice material you use, remember that practice questions, including ours, are independently authored preparation, not actual issuer or provider questions and not an official mock exam. You can try our practice questions at the main practice test site.
Frequently Asked Questions
The FY2025 TDLR statistics show it is selective: 24.46% for Journeyman NEC (1,402 of 5,731 attempts) and 20.56% for Journeyman Calculations (1,301 of 6,328 attempts). Those are attempt-level historical figures, not your personal odds or a combined license passing probability, so use them as context rather than a prediction.
In the FY2025 data, Calculations had the lower reported rate. In practice, difficulty depends on your background. Candidates strong in code navigation may struggle with multi-step math, while others have the reverse problem. Each portion requires 70% separately, so you need both.
No. A soft-bound NEC is allowed, but the NEC Handbook and loose-leaf, spiral-bound, or ring-bound copies are prohibited. Existing notes, highlighting, and underlining are fine, but the only authorized tabs are permanent index tabs manufactured or provided by the NEC publisher. Homemade or non-NEC tabs are not allowed.
Each portion has its own passing requirement, and attempts are unlimited within the eligibility period. A retake of one or both portions costs USD 78. Check the current bulletin and our TX-JE Exam Dates 2026: Testing Windows, Deadlines & Scheduling guide for rescheduling rules, including the two-day cancellation notice.
The currently linked bulletin carries an explicit notice that the 2026 NEC is effective September 1, 2026. The bulletin has unresolved rendering conflicts in its revision date and one reference line, so confirm the current PSI/TDLR bulletin before buying a book or writing edition-specific notes. Allowance to carry an older soft-bound book does not mean older-edition answers are tested.
Difficulty on this exam is manageable when you treat it as two distinct assessments, prepare the physical book carefully, and put your study hours where the scored items concentrate.
