TDLR Journeyman Exam Prep for Houston Electricians.
Houston is the largest electrical market in Texas and the densest concentration of journeyman candidates in the state. Between residential build-out across Cypress, Spring, and Sugar Land, the petrochemical corridor running through Pasadena and Deer Park, and the medical center expansion, the demand for licensed journeymen is structural — not cyclical.
What the TDLR exam pass rate actually looks like.
First-time pass rate is around 24-26% on the Calculations section, ~50-55% overall. 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. Houston's employer mix:
- CenterPoint Energy (transmission and distribution)
- Refinery and petrochemical electrical contractors along the Houston Ship Channel
- Texas Medical Center facility electricians (huge ongoing capital projects)
- Residential contractors building the Cypress / Spring / Katy / Sugar Land corridors
- Industrial maintenance at Halliburton, Schlumberger, and the oilfield service shops
The NEC topics that matter most for Houston 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:
- Industrial three-phase calculations (refinery + petrochem electrical contractors run a lot of 480V three-phase work)
- Motor sizing and motor protection (Article 430) — common across industrial and HVAC
- Service entrance calculations on large residential projects (Article 220)
- Grounding and bonding under high-soil-moisture Gulf coast conditions
Where you'll actually take the exam.
PSI operates testing centers at multiple Houston-area locations. Most candidates schedule at the Northwest or Southwest Houston site depending on which side of 610 they live on. PSI lets you reschedule once free; book early in the morning for the freshest cognitive state on the Calculations section.
