TX-ME Exam Dates 2026: Testing Windows, Deadlines & Scheduling

Are There Fixed TX-ME Testing Windows?

Unlike licensing exams that run on quarterly or biannual sitting windows, the Texas Master Electrician License Exam does not operate on a fixed calendar of testing dates published months in advance. TDLR (Texas Department of Licensing and Regulation) approves your application, and once approved you schedule your seat directly through PSI, the third-party administrator that runs the computer-based test. This means your personal "testing window" is really a scheduling appointment you control, subject to seat availability at your chosen PSI test center.

That flexibility is good news for candidates who want to test as soon as they feel ready, but it also means the real deadlines that matter for 2026 aren't about a testing calendar - they're about the 2026 NEC code transition and the one-year window TDLR gives you to finish licensing after your application is received. Both are covered in detail below, and both should shape when you sit for the exam far more than any notion of a "testing season."

The September 1, 2026 NEC Transition Deadline

The single most important date on the 2026 calendar for TX-ME candidates is September 1, 2026. According to PSI's bulletin revised July 9, 2026, the exam moves to the 2026 National Electrical Code for all examinations administered on or after that date. This dated notice supersedes any residual references to the 2023 code cycle that may still be circulating in older prep material.

If your test date falls before September 1, 2026, expect questions written against the prior code cycle. If it falls on or after that date, every scored item across both portions - Domains 1 through 10 in NEC Knowledge and Domains 11 through 20 in Calculations - will reference the 2026 NEC. Candidates who studied from an outdated code book, or who bring the wrong edition into the testing room, put themselves at a real disadvantage even before the first question loads.

Registration and Scheduling Mechanics

Before you can pick a date with PSI, TDLR has to approve your application. That approval is the gatekeeper for scheduling, so the practical "deadline" most candidates face is simply how quickly they can assemble a complete application. Here's the sequence:

1. Verify eligibility. You need 12,000 supervised on-the-job hours under a Texas-licensed Master Electrician plus a Journeyman Electrician license held at least two years. A Journeyman Industrial license does not count toward this requirement, and your supervising master must verify the hours. The full breakdown lives in our TX-ME Requirements 2026: Eligibility, Prerequisites & How to Qualify guide.
2. Submit the TDLR application along with the $45 license application fee.
3. Wait for TDLR approval to test. You cannot schedule with PSI until TDLR clears you.
4. Pay the PSI examination fee - $78 covers both portions in one sitting, and a $78 fee applies if you need to retake one or both portions later.
5. Schedule your seat at a PSI center offering computer-based testing in English or Spanish, subject to availability.

Exam Day Timing: Two Portions, 320 Minutes

Scheduling isn't just about picking a calendar date - it's about understanding how your appointment time is structured once you're in the seat. The TX-ME exam is split into two separately timed, separately passed portions, and unused time from one portion cannot carry over to the other. Plan your appointment length and mental pacing around this reality.

• NEC Knowledge portion: 75 administered questions (70 scored, 5 unscored), 150 minutes.
• Calculations portion: 33 administered questions (30 scored, 3 unscored), 170 minutes.
• Combined testing time: 320 minutes across both portions in a single visit.

Each portion requires a 70% score to pass, calculated independently. A strong Knowledge score cannot offset a weak Calculations score, and vice versa - a scheduling and study detail candidates often underestimate. If you're unsure exactly how the score threshold is applied per portion, our TX-ME Passing Score 2026: Exactly What You Need to Pass article walks through it in isolation.

The One-Year Licensing Completion Clock

Here is the deadline that most directly resembles a "window": TDLR requires that all licensing requirements - including passing both exam portions - be completed within one year after TDLR receives your application. Miss that window, and you may need to restart the application process, re-pay the $45 TDLR fee, and re-establish approval to test.

This makes your personal scheduling strategy important. If you fail one portion, you don't automatically lose your passing score on the other - but you do need to retake the failed portion (or both, if you choose) within that same one-year clock, paying the $78 PSI retake fee each time. Candidates who wait too long between attempts, or who schedule their first attempt late in the year after TDLR approval, risk running out of runway.

Scheduling Your Prep Around the 20 Domains

Once you know your target test date, work backward through the content. The exam draws from 20 named domains split across two portions - Domains 1 through 10 make up NEC Knowledge, and Domains 11 through 20 make up Calculations. Several domain names repeat across the two portions (for example, "Electrical Services, Service Equipment, and Separately Derived Systems" appears as both Domain 2 and Domain 12), but they test different skills: recall and code navigation in Knowledge, applied math in Calculations. A full walkthrough of every domain and its scored-item weight is available in our TX-ME Exam Domains 2026: Complete Guide to All 20 Content Areas article.

For a broader framework on structuring these weeks - including how to interleave open-book navigation drills with calculation practice - see our TX-ME Study Guide 2026: How to Pass on Your First Attempt. Running full-length practice sessions on ../ before your scheduled date is one of the most direct ways to rehearse the real 320-minute pacing under exam-like conditions.

Renewal Timing After You Pass

Passing both portions and receiving your license doesn't end the calendar-watching. The individual Master Electrician license is valid for just one year and renews for $45, with four TDLR-approved continuing education hours required each cycle - covering NEC updates, Texas law and rules, and NFPA 70E electrical safety. Mark your renewal date the moment your license issues so continuing education isn't a last-minute scramble.

Note also that the individual Master Electrician license is distinct from the separate Electrical Contractor business license; renewal timing and requirements for the contractor credential are handled separately from the individual license discussed here.
