Texas Electrician License Levels: Apprentice, Residential Wireman, Journeyman, Master

Texas has four primary electrician license tiers governed by TDLR (Texas Department of Licensing and Regulation), each requiring progressively more experience and authorizing a broader scope of work. If you are working toward an electrician license in Texas — or deciding which exam to sit for next — understanding how the tiers differ will save you time and study effort.

The Four Texas Electrician License Tiers

All three written exams are administered by PSI on behalf of TDLR. All are open book — you bring your own tabbed copy of the 2023 National Electrical Code (NEC). Loose-leaf, spiral-bound, or ring-bound copies are not permitted. A score of 70% or higher is required to pass each exam.

Electrical Apprentice: The Starting Point

The Electrical Apprentice registration allows you to legally work and gain experience under direct supervision of a licensed Journeyman or Master Electrician. There is no exam — you simply apply through TDLR, pay the fee, and register. You must be at least 16 years old.

The apprentice registration is the clock-starting mechanism. Every hour you work as a registered apprentice under a licensed electrician counts toward the 4,000, 8,000, or 12,000 hours you will need for the higher license levels. Each employer must complete an Experience Verification Form (Form ELC017) signed by the supervising licensee.

Apprentice registrations renew annually. Apprentices enrolled in a TDLR-registered apprenticeship training program satisfy their annual CE requirement through program enrollment rather than the 4-hour CE course required of licensed electricians.

Residential Wireman: The First Licensed Tier

The Residential Wireman license is the first tier that requires passing a written exam. It authorizes you to wire single-family and multi-family residential structures — a significant step up from working as an apprentice.

Experience required: 4,000 hours under a licensed Master Electrician or Residential Wireman, verified by Experience Verification Forms from each employer.

The exam focuses on NEC content relevant to residential wiring:

• NEC Residential Wiring and Branch Circuits (30%) — Article 210 in depth: the 6-foot receptacle spacing rule, 24-inch countertop spacing, GFCI requirements (210.8), AFCI requirements (210.12), the two required small appliance circuits (210.52(B)), laundry circuit, outdoor receptacles, garage receptacles, hallway receptacles, bathroom placement within 3 feet of basin, tamper-resistant receptacle requirements
• Services, Feeders, and Load Calculations (25%) — dwelling unit load calculation: 3 VA/sq ft general lighting load, small appliance circuit demand, range demand from Table 220.55, the 125% continuous load sizing rule
• Overcurrent Protection, Grounding, and Bonding (22%) — Articles 240 and 250: standard breaker ratings, EGC sizing (Table 250.122), grounding electrode system, neutral-to-ground bond at service only
• Wiring Methods and Materials (13%) — NM cable (Article 334), EMT (358), PVC conduit (352), burial depths, box fill calculations (314.16)
• Texas Licensing Rules and TDLR Regulations (10%) — Texas Occupations Code Chapter 1305, 16 TAC Chapter 73, license types and experience requirements

The most concentrated study area for the Wireman exam is Article 210. Candidates who know every receptacle spacing rule, every GFCI and AFCI requirement, and every exception in Article 210 consistently pass. Those who do not consistently struggle on a third of the questions.

Journeyman Electrician: The Broader License

The Journeyman Electrician license dramatically expands your scope. A Journeyman can perform electrical work on both residential and commercial projects. This is the license most working electricians hold as their primary credential.

Experience required: 8,000 hours — double the Residential Wireman requirement.

Important change as of March 11, 2025: The Journeyman exam was restructured into two separate parts:

• Knowledge portion — tests NEC concepts, definitions, installation requirements, and code application
• Calculations portion — tests mathematical application of NEC: load calculations, conductor sizing, conduit fill, motor circuit sizing

Both parts must be passed. Candidates can take them on the same day or separately. Check the current TDLR/PSI Candidate Information Bulletin for exact question counts and time limits, as these were updated with the March 2025 format change.

The Journeyman exam covers substantially more NEC territory than the Wireman exam:

• NEC Fundamentals across Articles 100, 110, 200, and 300
• Wiring methods across residential and commercial applications — more article coverage than Wireman
• Overcurrent protection and grounding in greater commercial depth
• Services and feeders with commercial demand calculations
• Special occupancies — Articles 500–590 covering hazardous locations, healthcare facilities, temporary installations
• Motors — Article 430: conductor sizing, overcurrent protection, controller requirements

The practical difference from the Wireman exam: the Journeyman exam requires fluency with commercial NEC articles that simply do not appear on the Wireman exam. Candidates transitioning from Wireman to Journeyman should focus their additional study on Articles 430 (motors), 500-series (special occupancies), and the expanded calculation requirements.

Master Electrician: The Top Tier

The Master Electrician license is required to operate an electrical contracting business in Texas. Every electrical contractor license in Texas must be qualified by a licensed Master. Masters can supervise both Journeymen and apprentices and are responsible for code compliance on all work performed under their license.

Experience required: 12,000 hours — typically representing 6+ years of combined apprentice and licensed electrician experience.

The Master exam is the longest: 100 questions in 300 minutes (5 hours). It tests all Journeyman content plus:

• Advanced load calculations — service sizing for commercial buildings, optional calculation methods, demand factor stacking
• Motor circuit calculations — Article 430 in full: conductor ampacity, overcurrent device sizing for different motor types, control circuit protection
• Emergency and standby systems — Articles 700, 701, 702
• Hazardous locations — Class I, II, and III; Division 1 and 2; Zone classification
• Contractor business requirements — vehicle identification, insurance requirements, supervision obligations, continuing education

The Master exam's advanced load calculation and motor circuit questions are where most candidates who fail lose points. These require working through multi-step NEC procedures quickly under time pressure — the 5-hour exam is generous by question count, but the calculation questions take significantly longer than straightforward code-lookup questions.

Annual License Renewal

All Texas electrician licenses — Residential Wireman, Journeyman, and Master — renew annually with TDLR. Renewal requires 4 hours of continuing education from a TDLR-approved provider, covering the NEC, Texas laws and rules, and NFPA 70E electrical safety. This is different from many states where electrician licenses renew every 2–3 years.

The Open-Book Advantage — and Its Real Limits

All three Texas electrician exams are open book with the 2023 NEC. This is an advantage, but only if you have prepared your code book and know how to navigate it quickly. The time limits are tighter than they appear once you factor in calculation questions.

Candidates who pass consistently report the same preparation pattern:

1. Tab the NEC before the exam using publisher-provided tabs only (no homemade tabs, no loose inserts)
2. Know where Articles 110, 210, 215, 220, 230, 240, 250, 300, 310, 314, 334, and 430 start from memory
3. Practice navigating from question to the relevant NEC section in under 90 seconds
4. Work through practice calculations with the NEC open — not memorizing answers, but practicing the lookup-and-calculate workflow

Memorizing specific code values is less important than developing fast, accurate code navigation. The exam rewards candidates who have internalized the NEC's structure, not those who have memorized facts that can be looked up.

Which Exam Should You Sit For

• You have 4,000 verified hours: Residential Wireman. First step to independence.
• You are a Wireman with 8,000 hours: Journeyman. The commercial scope expansion is a significant income and career upgrade.
• You are a Journeyman planning to start a contracting business: Master. Required to pull permits and hold an electrical contractor license in Texas.
