Journeyman Electrician Prep Course Texas: Passing TDLR
A journeyman electrician prep course in Texas only works if it drills the two skills the TDLR/PSI exam actually tests: fast NEC code lookups under a strict time limit, and electrical calculations done without a calculator app. Generic multi-state courses that skip Texas’s split exam format and its NEC-only reference rule waste study hours you don’t have.
Texas splits its journeyman written exam into two separately timed, separately scored sections, and a course built for a different state’s single-section format won’t match that structure. Picking a course that mirrors TDLR’s actual exam layout matters more than picking the course with the most video hours.
What does the Texas journeyman exam actually cover?
The Texas Department of Licensing and Regulation, through its vendor PSI, splits the journeyman written exam into an NEC Knowledge portion and a Calculations portion, each requiring a 70% score to pass. TDLR’s current Candidate Information Bulletin puts the NEC Knowledge portion at 59 scored questions in 130 minutes and the Calculations portion at 26 scored questions in 110 minutes, and time from one section does not carry over to the other.
Both sections are open book against the 2023 NEC, and TDLR confirms on its exam information page that candidates bring their own soft-bound copy. That single fact should drive most of your prep course decision: you’re not being tested on memorized facts, you’re being tested on how fast you can find the right table, article, or exception in your own book.
What should a Texas-specific prep course actually teach?
A course built for the TDLR exam should teach code navigation as a timed skill, not a reading assignment. If a course spends more time explaining electrical theory than running you through timed lookups in the actual 2023 NEC, it’s built for a licensing exam in general, not for TDLR’s format specifically.
Look for three things before you pay for a course:
- Practice questions in TDLR’s real split format (separate NEC Knowledge and Calculations sets, each timed to match the real 130-minute and 110-minute limits).
- Code navigation drills, not just answer keys, so you build the muscle memory to find Article 220 or a conduit fill table in under a minute.
- Worked calculation problems covering service sizing, feeder sizing, motor loads, and voltage drop, since Calculations is scored as its own pass/fail section and a weak score there fails you even with a strong NEC Knowledge score.
What should you skip?
Skip any course that treats “journeyman electrician exam prep” as one national product with a state selector bolted on. TDLR’s two-part format, its open-book NEC-only reference rule (no NEC Handbook, no loose-leaf binding), and its 7,000-hour eligibility threshold are specific enough that a course built primarily for another state’s single-section exam will leave gaps in exactly the areas TDLR tests hardest.
Also skip courses that don’t disclose which NEC edition they’re built on. Texas has referenced the 2023 NEC since October 1, 2023, and TDLR’s exam content is scheduled to move to the 2026 NEC on September 1, 2026. A course still teaching the 2020 code, or one that doesn’t say which edition it uses, can actively cost you points on exam day.
What does it cost and how long does it take to prepare?
Serious TDLR candidates typically spend 4 to 8 weeks in structured prep, splitting time between NEC lookup drills and calculation practice, on top of the 7,000 to 8,000 on-the-job training hours TDLR already requires before you’re eligible to test. Prep course prices for Texas-specific journeyman materials commonly run in the $20 to $150 range depending on whether you’re buying a standalone practice-question set or a full guide-plus-code-book bundle; the exam itself is a separate cost.
TDLR charges a $30 non-refundable application fee to review your license application, separate from the $78 examination fee PSI charges for the journeyman electrician exam, which covers both the NEC Knowledge and Calculations portions together. If you fail one portion, you retake only that portion, but you pay the $78 fee again for the retake.

What are the TDLR logistics you need to plan around?
You need 7,000 hours of on-the-job training under a Texas-licensed Master Electrician just to sit for the exam, and TDLR requires the full 8,000 hours before it issues the actual journeyman license, according to the journeyman electrician application page. You submit your application and $30 fee by mail, and once TDLR approves it, you schedule your PSI exam directly.
PSI runs testing centers in most major Texas metros, including Austin, Houston, Dallas, San Antonio, and El Paso, and you can schedule online or by phone once TDLR clears you. Bring your soft-bound 2023 NEC and a valid government-issued ID; electronic notepads are provided at the test center, so you don’t need your own calculator paper.
How AmpExam fits into a Texas prep plan
A generic study guide can teach you the code sections. What closes the gap on exam day is rehearsing the exact TDLR format: a timed NEC Knowledge set followed by a separately timed Calculations set. AmpExam’s practice tool is built around that split so you walk into the PSI test center having already felt the 130-minute and 110-minute clocks running out on you at home, where a wrong guess costs nothing.
FAQ
How many practice questions should I do before the TDLR exam? Aim for enough repetition that code lookups become automatic, typically several hundred practice questions split roughly in proportion to the real exam (about 70% NEC Knowledge, 30% Calculations). Volume matters less than timing yourself against TDLR’s actual 130-minute and 110-minute limits so pacing isn’t a surprise on test day.
Is the TDLR journeyman exam hard to pass? It’s a 70%-to-pass, open-book exam on material you’ve already worked with on the job, so the difficulty is mostly about speed under time pressure, not unfamiliar content. Candidates who fail most often run out of time on code lookups rather than not knowing the material at all.
Can I retake just the part of the TDLR exam I failed? Yes. TDLR and PSI score the NEC Knowledge and Calculations portions separately, so if you pass one and fail the other, you only retake the portion you failed. You’ll pay the $78 exam fee again for that retake, so it’s worth over-preparing the weaker section rather than risking a second sitting.
Do I need a separate calculator for the Calculations portion? You need your own calculator, but it must be silent, battery-operated, non-printing, and without an alphabetic keyboard; TDLR and PSI both bar programmable or text-capable calculators from the test room. A basic scientific calculator you’ve already practiced with is safer than borrowing an unfamiliar one on exam day.
