Why most candidates struggle
Why most TDLR candidates struggle
TDLR’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.

Texas amendments add complexity
TDLR uses NEC 2023 with state-specific amendments. Generic prep misses these and you walk in confident on the wrong rule.
Calculations under pressure
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.

TDLR exam questions, answered
What's on the TDLR Journeyman electrician exam?
80 multiple-choice questions across calculations, wiring methods, grounding and bonding, branch circuits, motors, and general code. The Calculations section is where most candidates lose points. The exam is graded by PSI to TDLR's domain weighting.
How long is the TDLR exam and what's the passing score?
The exam is 4 hours and you need 70% to pass. It is open-book against the NEC 2023 plus Texas amendments. The book is allowed; tabs and highlights you brought yourself are typically allowed. Verify the current rule with PSI before exam day.
How do I register for the TDLR Journeyman exam?
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.
How is JourneymanIQ different from Mike Holt or Tom Henry?
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.
Can I bring an electronic codebook into the TDLR exam?
No. Texas exams require a physical printed copy of the NEC 2023 with Texas amendments. Tabs and highlights are typically allowed; sticky notes and loose pages are not. Confirm the current rule on the PSI candidate bulletin before your test date. Rules occasionally change.
How long should I study for the TDLR exam?
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.
