Texas 2023 Master Electrician Exam Prep and Study Guide: 12 Practice Exams + 2 Full Final Exams: Trusted by 50k Electricians

When you’re ready to move from journeyman-level work into master-level responsibility in Texas, the exam is only part of the challenge. The bigger task is proving—on paper and under time pressure—that you can interpret the National Electrical Code confidently, choose the right installation requirements, and complete calculations with professional accuracy.

This Texas Master Electrician Exam Prep and Study Guide is built for that exact moment. With 12 practice exams plus 2 full final exams, it gives you repeated, realistic opportunities to practice how the test actually feels: locate the code section, apply it correctly, and keep moving. You’ll build the habits that matter most for an open-book code exam—fast navigation, clean reasoning, and a calm approach to problem solving.

Instead of relying on vague studying, you’ll use practice-based preparation to spot weak areas, reinforce your strengths, and sharpen your timing. If you’ve ever walked out of a test thinking, “I knew it… I just couldn’t find it fast enough,” this format is designed to help you fix that.

This prep is a fit for:

• Texas journeyman electricians planning to upgrade to Master Electrician
• Test-takers who want to improve NEC speed and accuracy in an open-book setting
• Electricians who want consistent practice with the kinds of code interpretation and calculation questions used on the licensing exam
• Busy professionals who want a structured way to study—without wasting time

Exam Details

The Texas Department of Licensing and Regulation (TDLR) contracts with PSI to deliver electrician examinations. The Texas Master Electrician written exam is organized into two separate portions: NEC Knowledge and Calculations. Each portion is multiple-choice, and you must pass each portion with a minimum score of 70%.

• NEC Knowledge Portion: 75 items (including 5 non-scored items) with 150 minutes to complete
• Calculations Portion: 33 items (including 3 non-scored items) with 170 minutes to complete
• Passing requirement: 70% correct to pass each portion
• Exam fee: $78 for both portions (retake fee is $78 if you fail one portion or both)

The “two-portion” setup matters for your study plan. Even if you feel confident reading code, the calculations portion rewards a different skill set: steady math, correct assumptions, clean steps, and the ability to avoid small errors that cost points. Your prep should train both skills—code navigation and calculation execution—so neither portion becomes a surprise.

The exam content outline highlights major topic areas that commonly appear at the master level. While specific questions vary, your practice should routinely touch the kinds of work you see on real projects: services and equipment, grounding and bonding, feeders and branch circuits, wiring methods, devices and equipment, motors and generators, special occupancies and conditions, and more. Calculations practice often includes load and sizing work that depends on choosing the correct code references and applying them correctly.

Open Book Test

The examinations are open book. The allowed reference is the National Electrical Code (NEC), 2023 Edition, and the Texas Candidate Information Bulletin includes clear rules about what is allowed and what is not allowed in the exam room. The exam also states that effective October 1, 2023, examinations are referenced to the 2023 NEC Code Book.

What is allowed:

• You are responsible for bringing your own NEC 2023 to the exam site.
• Soft-bound editions are allowed.
• Your NEC book may be highlighted, underlined, and/or contain notes prior to the exam session.
• NEC books may be tabbed with permanent index tabs manufactured and/or provided by the NEC publisher.

What is not allowed:

• You may not write, highlight, underline, index, or mark your NEC book during the examination session.
• Homemade/DIY/non-NEC tabs are not permitted.
• Loose-leaf, spiralbound, or ring-bound copies of the NEC book are not allowed in the examination room.
• Additional paper (loose, taped, adhered, stapled, etc.) is not allowed in the exam room.
• The NEC Handbook is not allowed in the examination room.

Open book does not mean easy—it means the exam rewards the electrician who can find the right rule quickly and interpret it accurately. A strong prep strategy focuses on NEC navigation: knowing where definitions live, how chapters are organized, how to use the index effectively, and how to move between articles, tables, and exceptions without losing time.

Licensing Steps

Texas Master Electrician licensing is handled through TDLR. In general, the process includes meeting experience requirements, submitting your application, receiving approval to test, scheduling through PSI, passing the exam portions, and then keeping your license current through renewal.

1. Meet the experience requirements. TDLR’s Master Electrician requirements include holding a Journeyman Electrician license for at least two years and documenting 12,000 hours of on-the-job training under the supervision of a Texas-licensed Master Electrician.
2. Document your experience. Experience must be verified as required by TDLR. Make sure your documentation is complete and matches how the state expects hours and supervision to be reported.
3. Submit your initial application by mail. TDLR states you must apply by mail for the initial Master Electrician license application, and it includes a non-refundable $45 application fee.
4. Receive eligibility approval. Once TDLR approves your eligibility, you receive instructions to schedule your exam.
5. Schedule your exam with PSI. You’ll select a test center, date, and time through PSI’s scheduling process.
6. Pass both portions of the exam. You must pass NEC Knowledge and Calculations at the required score level.
7. Renew to keep your license active. TDLR notes electrician licenses are valid for one year and must be renewed annually.

Because the exam is open book and code-referenced, your documentation and eligibility steps are only one side of the process. The other side is building exam performance: timed problem solving, code lookup skills, and consistent accuracy across a wide range of NEC topics.

State Requirements

TDLR regulates electricians in Texas, and state guidance emphasizes that anyone who performs—or offers to perform—non-exempt electrical work in Texas must be licensed and perform that work through a licensed electrical contractor.

For Master Electrician applicants, the key state-level requirements and expectations typically include:

• Experience and supervision: documented on-the-job hours under appropriate supervision, consistent with TDLR requirements
• Journeyman status: meeting the required time holding the Journeyman Electrician license before applying
• Application method: initial application submitted by mail with the stated fee
• Exam approval and scheduling: eligibility approval before scheduling through PSI
• Ongoing maintenance: annual renewal to keep licensing current

Master licensure reflects a higher level of responsibility, including planning, oversight, and code compliance decisions that affect safety and project outcomes. That’s why the exam looks beyond basic definitions and tests whether you can apply NEC requirements in real-world scenarios.

Reference Books

• National Electrical Code (NEC), 2023 Edition
  The allowed open-book reference for Texas electrician examinations. Candidates must bring their own compliant NEC to the exam site. Soft-bound editions are permitted; loose-leaf, spiralbound, or ring-bound copies are not allowed. Publisher-provided permanent index tabs are allowed; homemade/DIY tabs are not.

Test Information and Study Materials

Good preparation includes knowing what to expect at the test center and training yourself to work within the exam structure. The Texas Candidate Information Bulletin explains that both portions are multiple choice, and time does not roll over from one portion to the next. That means your pacing for NEC Knowledge is separate from your pacing for Calculations.

Build your study plan around two outcomes:

• NEC Knowledge performance: locate the correct rule quickly, interpret it correctly, and avoid overthinking exceptions unless the question specifically directs you to consider them.
• Calculation consistency: solve methodically, check units, confirm assumptions, and avoid “rushing errors” that turn correct knowledge into wrong answers.

How to train with 12 practice exams + 2 full finals:

• Start with diagnostic practice. Take one practice exam early to identify weak areas. Don’t guess what to study—use your results to decide.
• Create a miss-tracker. For every missed question, note the topic and the NEC area involved. Over time you’ll see patterns (grounding, motor rules, conductor sizing, special occupancies, etc.).
• Practice code navigation on purpose. When you review, do a “second lookup” even if you got the question right. The goal is to shorten the time it takes you to confirm an answer.
• Use timed sessions. Set a timer and work in blocks that match exam pressure. Timing practice helps you avoid getting stuck and teaches you when to move on.
• Separate your study by portion. Some days should be code-heavy; other days should be calculation-focused. This mirrors the two-portion exam and prevents one skill from dragging down your score.
• Save the finals for later. Treat the full final exams like dress rehearsals. Use your NEC book exactly as you plan to use it on test day.

Open-book success tips that matter for Texas:

• Get comfortable with the index. The index can be faster than flipping chapters if you know how to search terms effectively.
• Know where tables live. Many time-consuming questions involve tables. Practice locating them quickly and reading them correctly.
• Reduce “hunt time.” The exam is timed. Every minute you spend searching is a minute you’re not answering questions.
• Stay compliant. Use only NEC publisher-provided permanent index tabs. Avoid anything that risks non-compliance on exam day.

Most electricians don’t fail because they “don’t know electrical work.” They struggle because test-day pressure exposes gaps in navigation, pacing, or calculation accuracy. Practice exams help you train those exam-specific skills so your knowledge shows up when it counts.
