The book is huge
NEC 2023 has more than 800 pages. Without speed-navigation skills, you’ll time out before answering everything.
Real Texas-focused practice. Since March 11, 2025 the TDLR exam is two separately-scored parts: NEC Knowledge (59 questions, 130 minutes) and Calculations (26 questions, 110 minutes), timed separately and open book against your own NEC 2023. Time and code navigation kill most candidates. We train both.
15 questions, about 15 minutes, no signup. You get a domain-by-domain weakness map for the two-part Journeyman exam, so you study the gaps instead of everything.
Take the free diagnosticTDLR’s FY2024 published statistics show 2,365 passes out of 8,490 Journeyman exam attempts. That works out to a 27.86% overall pass rate, which means roughly seven in ten attempts walked away without a license. The exam is open-book, but the book is huge and the clock runs fast. Three things sink most candidates.

Since March 11, 2025 the exam is two parts. You need 70% on each, and the Calculations part is scored on its own, so a strong code score can't carry weak math. Only 20.56% pass the Calculations part.
Voltage drop, conduit fill, motor sizing. The math isn’t hard. Doing it in a stressed exam state, with the timer in your peripheral vision, is.
Every question tagged to a TDLR domain and an NEC article. The engine surfaces what you’re weakest on so your study time goes to the topics that’ll lose you points.

85 multiple-choice questions in two separately-scored parts since March 2025: NEC Knowledge (59 questions) and Calculations (26 questions). The Calculations part is where most candidates lose points, and it is now graded on its own. PSI grades it to TDLR's domain weighting.
The exam is 240 minutes across two separately-timed parts (130 minutes for NEC Knowledge, 110 for Calculations) and you need 70% on each. It is open-book against the NEC 2023. You bring your own soft-bound NEC 2023. You can highlight and underline it ahead of time, but only permanent publisher index tabs are allowed. Homemade or stick-on tabs aren't allowed and the proctor can make you pull them. Verify the current rule with PSI before exam day.
TDLR licenses Journeyman Electricians in Texas. After meeting the work-experience requirement (at least 8,000 hours under a Master Electrician), you submit an application to TDLR, pay the application fee, then schedule the exam through PSI Services. PSI publishes test centers across Texas.
Mike Holt and Tom Henry sell static prep: videos, books, and timed tests that don't adapt to what you already know. JourneymanIQ tracks every question you answer and surfaces the topics you're weakest on. We also focus on the codebook-speed skill (finding rules fast) that decides exam day. Honest comparison: their materials are deeper if you're starting from zero. Our platform is sharper for the last 30 days before your test.
No. Texas exams require your own soft-bound printed copy of the NEC 2023. You can highlight and underline ahead of time, and permanent publisher index tabs are fine. Homemade tabs, sticky notes, loose pages, and loose-leaf, spiral, or ring-bound books are not. Confirm the current rule on the PSI candidate bulletin before your test date. Rules occasionally change.
Most candidates need 30 to 60 days of focused prep. If you failed by a few points last time, 30 days is usually enough. If you're starting from your apprentice license with no recent code review, plan on 60. Our 30-day plan is built around 60 to 90 minutes per day.
