Time remaining from one portion does not transfer to the other portion. Candidates should therefore practice the NEC Knowledge and Calculations sections independently and develop a pacing strategy for each.

Open Book Test

The Texas Master Electrician examination is an open book test.

The approved technical reference is the National Electrical Code, NEC, 2026 Edition. Candidates are responsible for bringing their own acceptable NEC book to the examination site.

The examination permits an acceptable soft-bound NEC reference. Loose-leaf, spiral-bound, and ring-bound NEC copies are not permitted in the testing room.

The rental NEC included with this package is highlighted and tabbed to support study and reference navigation. Candidates should use the book repeatedly during the 6 months of course access so that major article locations, tables, definitions, and calculation rules become familiar before examination day.

Open-book testing still requires preparation. Candidates who know the general location of a code requirement can spend more time applying the rule and less time searching through the NEC.

State Requirements

A Texas Master Electrician is licensed to install, maintain, or extend electrical wiring systems and the related apparatus, equipment, and service entrance conductors within the scope established by Texas law.

To apply for a Texas Master Electrician license, an applicant must have held a Journeyman Electrician license for at least two years.

The applicant must also document at least 12,000 hours of on-the-job training under the supervision of a Master Electrician licensed in Texas.

Qualifying experience must be documented and verified. Texas does not allow Journeyman Industrial Electrician experience to be used to qualify for the Master Electrician credential.

The Master Electrician license is an individual credential. A Texas Electrical Contractor license is a separate business license. An electrical contractor must employ a licensed Master Electrician who serves as the Master Electrician of Record. The Master Electrician may also own the contracting business.

A Master Electrician may generally be assigned to only one Electrical Contractor unless the Master Electrician owns more than 50% of the electrical contracting business.

Texas electrician licenses are valid for one year from the date of issuance and are subject to annual renewal requirements.
