Texas Electrician Exam Simulator (TDLR Journeyman)
A simulator is not there to make you feel good. It is there to show whether your timing, rule selection, and calculation setup hold up across both parts of the current TDLR exam. If it still runs the old single 80-question test, it is rehearsing the wrong exam.

Most prep sites and old forum threads still describe one 80-question test scored as a whole. That format is gone. On March 11, 2025, TDLR split the Journeyman exam into two parts that are timed and scored independently. If a simulator blends the parts into one number, it cannot show you the thing that actually fails people, which is a weak Calculations part hiding behind a decent Knowledge score.
- NEC Knowledge: 59 questions, 130 minutes, 70% to pass.
- Calculations: 26 questions, 110 minutes, 70% to pass.
- Total: 85 questions, two parts, scored separately. Time from one part does not roll into the other.
- Conditions: open book on the NEC 2023, your own soft-bound copy, $78 for both portions.
What a Texas simulator should measure
A score is not the point. The point is finding which mistakes keep costing you, on which part, under the real clock. A simulator earns its time only if it tells you where to go next.
- Known-answer speed: can you bank the easy NEC Knowledge points without opening the book?
- Lookup speed: can you find the controlling rule in the NEC 2023 fast enough to beat the per-question clock?
- Code-family recognition: can you tell whether the answer lives in 210, 220, 240, 250, 310, 314, or 430 before you flip a page?
- Calculation setup: can you name the problem type, dwelling load or motor sizing or box fill, before you touch a number?
- Skip discipline: can you move off a slow Calculations question before it eats the clock?
- Repeat misses: are the same traps still showing up on the same part run after run?
The JourneymanIQ simulator path
- Diagnostic for your first domain-by-domain weakness map across both parts.
- Daily practice routed by your misses, weighted to the part that scored lower.
- Timed sets that rehearse each part on its own clock, not a blended one.
- Full-length two-part mock only after the weak part actually moves.
