TDLR Journeyman Exam Prep for San Antonio Electricians.
San Antonio runs on institutional electrical work: four military installations under Joint Base San Antonio, the South Texas Medical Center, and a manufacturing base anchored by the Toyota truck plant on the south side. Add the housing push through Alamo Ranch, Stone Oak, and New Braunfels and you get steady demand for licensed journeymen on both the industrial and residential sides of the trade.
What the TDLR exam pass rate actually looks like.
The TDLR FY2025 overall pass rate was 27.52% (1,390 passed of 5,050 (27.52%)), per TDLR Electrician Exam Statistics. The Calculations part is where most candidates lose points. The state-wide failure rate is what most candidates underestimate.
The local market that's hiring you.
The exam tests universal NEC content — but the kind of work you'll actually do shapes which articles you should focus on. San Antonio's employer mix:
- Joint Base San Antonio facility and DoD electrical contractors (Lackland, Fort Sam Houston, Randolph)
- CPS Energy, the largest municipally owned electric utility in the country
- Toyota Motor Manufacturing Texas and its south-side supplier network
- South Texas Medical Center hospital and lab electrical work
- Residential builders across Alamo Ranch, Stone Oak, Schertz, and New Braunfels
The NEC topics that matter most for San Antonio candidates.
The exam content is statewide-uniform. But the practical work you'll do day-one shapes which sections to drill hardest before test day:
- Motor and transformer calculations (Article 430 and 450) for the manufacturing and base-facility work
- Dwelling service calculations (Article 220) for the fast-growing subdivisions
- Grounding and bonding fundamentals, tested hard and used daily on institutional projects
- Conductor ampacity adjustments for South Texas heat (high ambient correction factors)
Where you'll actually take the exam.
PSI operates San Antonio-area testing centers, and candidates from the Hill Country and South Texas often test here rather than drive to Austin or Corpus Christi. Book a weekday morning slot if you can. You want the Calculations part done before the afternoon slump.
