What Is TX-JE?

TL;DR
  • TX-JE here means the Texas Journeyman Electrician License Exam, administered by PSI for the Texas Department of Licensing and Regulation (TDLR).
  • The exam has two separate computer-based portions: NEC Knowledge (56 scored items, 130 minutes) and Calculations (24 scored items, 110 minutes).
  • Each portion needs 70% on its own, and both are covered by one USD 78 exam fee.
  • TDLR may approve testing at 7,000 verified hours, but license issuance still requires 8,000 approved hours.

What TX-JE Means on This Site

On this site, TX-JE is the shorthand for the Texas Journeyman Electrician License Exam: the written, computer-based examination a candidate must pass as part of earning a Texas journeyman electrician license. It is not a general-purpose certificate or a vendor credential. It is a state licensing step, and the state is Texas.

The acronym is easy to confuse, since other credentials abbreviate similarly. Everything in this article refers only to the Texas licensing exam. If you want the same topic under different search phrasings, the site also covers what TX-JE stands for and the meaning of TX-JE.

Preparation is not licensure: Studying for the exam does not make you eligible to sit for it, does not demonstrate field competence, and does not issue a license. Eligibility, testing, and issuance are three separate gates, and this article treats them separately.

Who Runs the Exam and Who Delivers It

Two organizations matter. The Texas Department of Licensing and Regulation (TDLR) is the governing body: it sets eligibility, reviews experience, and issues and renews the license. PSI Services LLC is the provider that delivers the exam at its test centers and publishes the Electrician Candidate Information Bulletin that TDLR links from its electrician exam page.

That bulletin is the authority for the content outline and reference rules discussed below. An older TDLR-hosted bulletin updated March 30, 2023 can still be found by search, but it describes a superseded combined-exam arrangement and should not override the currently linked bulletin. If you find a study guide or forum post built on that older document, treat it as a version-check warning rather than as a source.

Two Portions, Two Timers, Two Passing Standards

Since March 11, 2025, the exam has been delivered as two separate written portions. Both are computer-based multiple choice. The Calculations portion is not a hands-on practical assessment; it is worked numerically, on a calculator, in the same multiple-choice format.

FeatureNEC KnowledgeCalculations
Total questions5926
Unscored questions32
Scored questions5624
Time allowed130 minutes110 minutes
Passing requirement70%70%
FormatComputer-based multiple choiceComputer-based multiple choice

Three practical points follow from this structure:

  • Each portion has its own timer and its own passing requirement. Strength on one does not offset weakness on the other.
  • Unused time does not roll over. Finishing NEC Knowledge early does not buy extra minutes for Calculations.
  • No required order and no combined line. Do not plan around an "85-question, four-hour exam"; that is not how the current route is described.

English and Spanish are both available at PSI test centers. For a deeper look at how difficult each portion tends to feel, see How Hard Is the TX-JE Exam? and the plain-language breakdown in TX-JE Passing Score.

What the Exam Covers: The 20-Row Outline

The published outline is two ten-heading outlines, one for each portion. The site's "20 domains" is a serialization of those two lists, not a claim by the issuer that there are 20 unique weighted domains. Names repeat across the halves because each portion has its own row for the same subject. Those repeated rows are distinct and should not be merged.

Also note what the published numbers are: scored-item allocations, not percentage weights. The scored allocations total 56 for NEC Knowledge and 24 for Calculations. Treat them as how many scored items the outline assigns to each heading, and avoid converting them into official percentages. For the full row-by-row walkthrough, see the TX-JE exam domains guide.

NEC Knowledge (Domains 1-10)

Domains 1-3: Foundations, Services, Feeders

The opening rows set up vocabulary and the supply side of an installation.

  • Domain 1, Definitions, Theory, and Plans (3 items): code definitions, electrical theory and plan reading.
  • Domain 2, Electrical Services, Service Equipment, and Separately Derived Systems (6 items): load knowledge, fault current, service equipment, temporary wiring, grounding/bonding and transformers.
  • Domain 3, Electrical Feeders (3 items): feeder load knowledge, grounded conductors and feeder grounding/bonding, and overcurrent protection.

Domains 4-6: The Heaviest Knowledge Rows

These three headings carry the largest scored allocations in NEC Knowledge, at ten items each. That is an item count, not a published weight, but it tells you where the outline concentrates questions.

  • Domain 4, Branch Circuits and Conductors (10): GFCI/AFCI protection, branch circuits, branch-circuit overcurrent protection, conductors, and grounding/bonding conductors.
  • Domain 5, Electrical Wiring Methods and Electrical Materials (10): raceways/cable trays, boxes/enclosures, cabinets/panels, cables/cords and underground wiring.
  • Domain 6, Electrical Equipment and Devices (10): receptacles/switches, luminaires, air-conditioning/refrigeration/heating equipment, appliances and workspace clearance.

Domains 7-10: Motors, Controls, Special Conditions, Newer Technology

  • Domain 7, Motors and Generators (5): motors and generators.
  • Domain 8, Electrical Control Devices and Disconnecting Means (1): control devices and disconnecting means.
  • Domain 9, Special Occupancies, Equipment, and Conditions (6): special occupancies, swimming pools/fountains/similar installations, RVs/mobile homes/park trailers/marinas, data-processing/communications equipment, emergency systems and miscellaneous equipment.
  • Domain 10, Renewable Energy Technologies (2): photovoltaics and electrical vehicle chargers.

Calculations (Domains 11-20)

The Calculations outline mirrors the same subject areas, with its own allocations. Because it is a separate portion with a separate pass requirement, its rows deserve separate study time.

DomainNameScored itemsSubjects
11Calculations and Theory2Electrical theory
12Electrical Services, Service Equipment, and Separately Derived Systems4Load calculations, service equipment, grounding/bonding and transformers
13Electrical Feeders3Feeder load calculations and overcurrent protection
14Branch Circuit Calculations and Conductors4Branch-circuit calculations, overcurrent protection, conductors, and grounding/bonding conductors (the outline continues on p. 14)

19Special Occupancies, Equipment, and Conditions3RVs/mobile homes/park trailers/marinas, data-processing/communications equipment and miscellaneous equipment
20Renewable Energy Technologies1Electrical vehicle chargers and photovoltaics

In Calculations, Domains 12 and 14 carry the largest allocations at four items each. One instruction applies throughout: assume copper conductors unless the question directs otherwise, and use exceptions or optional calculation methods only when the question directs you to.

The 2026 NEC Transition and the Source Conflicts

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 notice is the basis for preparing against the 2026 edition.

The bulletin itself, however, contains rendering discrepancies that this article reports rather than smooths over:

  • The visible cover says Updated 7/9/2026, while the extracted text says Updated 9/15/2026.
  • On printed page 8, the rendered allowed-reference line still reads 2023 Edition, while the extracted text reads 2026 Edition. Both versions display the explicit September 1, 2026 transition to the 2026 NEC.
Confirm before you buy: The dated notice supports 2026 preparation, but you should check the current PSI/TDLR bulletin before purchasing a code book or any edition-specific study material. Permission to bring an older soft-bound NEC is not proof that older-edition answers are tested; questions reference the designated tested edition.

This is also why older competitor pages built around the 2023 NEC or an aggregate exam description should be read as outdated rather than authoritative.

Open-Book Rules: Books, Tabs, Notes, Calculators

The exam allows a code book, but the rules are strict, and the penalty for misunderstanding them is arriving at the test center with a book you cannot use.

ItemStatus
Soft-bound NEC (under the current text, any soft-bound edition is admitted)Allowed
NEC HandbookProhibited
Loose-leaf, spiral-bound or ring-bound copiesProhibited
Existing notes, highlighting and underliningAllowed
Permanent index tabs manufactured/provided by the NEC publisherAllowed
Homemade, DIY or non-NEC tabsNot authorized
Adding paper or writing/marking in the reference during the examNot allowed
Electronic notepadSupplied at the test center
Silent, battery-powered, nonprogrammable calculator with no alphabetic keyboard or paper printingAllowed

Because annotation is limited to what already exists in the book, the time to mark it up is during preparation, using the publisher's own tabs. Your tab placement should follow the outline: Domain 4 through 6 subjects, along with the service, grounding and motor articles, are natural anchors. The calculator rule matters just as much; practice with the exact kind of device you will be permitted to use.

7,000 Hours to Test, 8,000 Hours to Be Licensed

Eligibility and issuance are different events, and mixing them up is a common source of confusion.

  • Early testing: TDLR may approve a candidate to test at 7,000 verified qualifying on-the-job hours worked under a Texas-licensed Master Electrician.
  • Issuance: the license itself requires 8,000 approved hours, supervisory verification, the application, and background review.
  • Verification: each supervising Master Electrician must verify the applicable experience.
  • Deadline: all requirements must be completed within one year after TDLR receives the application.

Passing both portions, then, does not by itself produce a license. Attempts are unlimited within the eligibility period, but that period is bounded by the one-year completion window. The full prerequisite picture is in TX-JE Requirements, and scheduling considerations are in TX-JE Exam Dates.

Fees and Test-Day Mechanics

ItemAmount
Exam fee (covers both portions)USD 78
Retake of one or both portionsUSD 78 (not USD 39 per portion)
Initial TDLR application fee (separate)USD 30

On test day, expect the following:

  • Government identification that matches your registration.
  • Arrival 30 minutes early.
  • At least two days' notice to cancel or reschedule.
  • A tutorial of up to 15 minutes, which sits outside examination time.

For a full pricing breakdown, including how fees combine over the licensing process, see TX-JE Certification Cost.

What the Historical Pass Data Does and Does Not Say

TDLR's Fiscal Year 2025 exam statistics report three separate rows for the journeyman level:

RowPass ratePasses / attempts
Journeyman NEC24.46%1,402 / 5,731
Journeyman Calculations20.56%1,301 / 6,328
Separate unsplit Journeyman row27.52%1,390 / 5,050

Read these carefully. They are distinct historical attempt-level cohorts. They are not counts of unique first-time candidates, not a combined-license passing probability, and not results for the 2026 NEC examination. Do not multiply the two component rates together, do not blend the unsplit row with the split rows, and do not treat any of them as a forecast of your own result. More context is in TX-JE Pass Rate.

A TX-JE-Specific Prep Sequence

Because the portions are scored separately, a sensible plan builds NEC navigation first, then calculation fluency on top of it. This sketch is tied to the outline rather than to a generic calendar; adjust the pace to your own schedule. A fuller method is in the TX-JE Study Guide, and a quick-reference recap is in the TX-JE cheat sheet.

Phase 1

Book setup and Domains 1-3

  • Apply publisher-made tabs to your soft-bound NEC.
  • Work definitions, theory and plan reading, then service, grounding/bonding and feeder subjects.
Phase 2

Domains 4-6, the ten-item rows

  • Spend the most reading time on branch circuits, wiring methods and equipment, since each carries ten scored items.
  • Practice finding GFCI/AFCI, raceway fill, box and workspace-clearance rules quickly.
Phase 3

Domains 7-10 and special conditions

  • Cover motors and generators, disconnecting means, pools, RVs/marinas, emergency systems, photovoltaics and EV chargers.
Phase 4

Calculations, Domains 11-20

  • Start with services and branch circuits (Domains 12 and 14), then feeders, motors and equipment.
  • Practice with an allowed-style calculator and the copper-unless-directed assumption.

Any practice material you use, including the questions on our main practice test site, is independently authored supplementary preparation. It is not actual issuer or provider content, not an official mock exam, and not a measure of practical field competence.

After the License: Term, Renewal, and Work

Once issued, the journeyman license has a one-year term. Annual renewal costs USD 30 and requires four hours of TDLR-approved continuing education covering the NEC, Texas electrician law and rules, and NFPA 70E safety. Those renewal topics are not extra exam domains.

Journeyman licensure matters because it is the credential employers look for when staffing electrical crews in Texas. For role types, see TX-JE jobs. For pay, the site's salary guide and the broader worth-it analysis take a dated, source-based approach rather than assuming a guaranteed license premium. No article here guarantees passing, earnings, eligibility, or issuer endorsement.

Frequently Asked Questions

What is the TX-JE exam?

It is the Texas Journeyman Electrician License Exam, delivered by PSI Services LLC for TDLR. It consists of two computer-based multiple-choice portions: NEC Knowledge and Calculations.

Do I have to pass both portions?

Yes. Each portion has its own timer and its own 70% requirement, and neither portion replaces the full route. The USD 78 exam fee covers both portions, and retaking one or both also costs USD 78.

Can I bring any NEC book and add my own tabs?

No. Bring a soft-bound NEC; the NEC Handbook and loose-leaf, spiral-bound or ring-bound copies are prohibited. Only permanent tabs manufactured or provided by the NEC publisher are authorized, and homemade or non-NEC tabs are not.

Do I need 8,000 hours before I can take the exam?

Not necessarily. TDLR may approve testing at 7,000 verified qualifying hours under a Texas-licensed Master Electrician, but license issuance requires 8,000 approved hours, supervisory verification, application and background review.

Which NEC edition should I study?

The current bulletin's dated notice designates the 2026 NEC, effective September 1, 2026. Because the bulletin shows rendering discrepancies, confirm the current PSI/TDLR bulletin before buying a book or edition-specific materials.
