Passing the Texas Master Electrician exam requires more than just reading the code. You need a structured plan that covers every NEC Knowledge subject area, drills your code-navigation speed under exam conditions, and builds the calculation skills tested in the second portion — all before test day.

This 30-day checklist is built around the open-book NEC 2026 and mirrors the two separately scored portions administered by PSI for TDLR: the NEC Knowledge portion (TX-MST-KNOW — 75 items in 150 minutes: 70 scored + 5 unscored pretest) and the Calculations portion (TX-MST-CALC — 33 items in 170 minutes: 30 scored + 3 unscored). Weeks 1–2 build your NEC Knowledge across the ten official subject areas, Weeks 3–4 shift entirely to the Calculations blueprint and full-length simulations, and day 30 is a complete mock exam. Use it alongside Master Electrician Practice for daily practice questions, AI Tutor explanations, and progress tracking.

Need the eligibility details first? Texas requires a journeyman license held for at least 2 years and 12,000 hours of on-the-job training under a Texas-licensed master electrician, with your application approved by TDLR before you schedule your exam at PSI.

The Four-Week Structure

Week 1: NEC Knowledge Foundations — Register for both portions, prepare your NEC 2026, and master the definitions, theory, services and service-equipment knowledge at the top of the KNOW blueprint.
Week 2: NEC Knowledge — Remaining Areas — Feeders, branch circuit conductors, wiring methods, equipment & devices, motors, control devices, special occupancies and renewable energy — the rest of the ten KNOW subject areas.
Week 3: Calculations Foundations — The 125% continuous-load rule, service/SDS sizing (8 scored items), feeder and branch-circuit calculations, wiring-method calcs, and motors & generators (6 scored items) per the TX-MST-CALC blueprint.
Week 4: Simulations & Mock Exam — Full-length TX-MST-CALC and TX-MST-KNOW simulations, open-book navigation speed drills, targeted weak-area review from your mistake log, and a complete mock exam on day 30.

Week 1: NEC Knowledge Foundations: Register, Code Setup & Core Articles (TX-MST-KNOW)

Register for both exam portions, get your NEC 2026 ready, and build the definitions, theory, services and service-equipment knowledge the NEC Knowledge portion tests first.

Register & Review the Official Exam Requirements

Weak-Area Review from the Full Mistake Log

☐Revisit the mistake log you have kept since Day 1 and identify your 2–3 worst subject areas across both portions.
☐Spend the day on targeted practice in exactly those areas — no new general content.
☐Ask the AI Tutor to explain any code requirement that still does not click.

Light Review & Mistake Log Consolidation

☐No new content. Skim your notes and mistake log only.
☐Rehearse the numbers cold: 125% continuous rule, standard ratings in 240.6, and which article owns which topic (230 services, 250 grounding, 430 motors).
☐Review the day-30 mock plan and how you will split the two portions.

Rest & Exam-Day Prep

☐No studying beyond light review — let the material consolidate.
☐Prepare exam-day materials: photo ID, TDLR approval notice, soft-bound NEC 2026 with tabs, and a non-programmable calculator.
☐Go to bed early. Aim for 8 hours of sleep.

Final Mock Exam Day

☐Sit the full mock back to back with a short break: TX-MST-KNOW (75 items, 150 minutes) then TX-MST-CALC (33 items, 170 minutes) — open book, strictly timed, no interruptions.
☐Score yourself at 70% on each portion’s scored items, just like the real exam.
☐Review every miss, then schedule your real exam at PSI — you are ready.

💡 Tips for Maximizing This Checklist

1.Consistency over intensity: Studying 2 hours every day is vastly more effective than cramming 8 hours on weekends.
2.Always study with the code open: Both exam portions are open book — every practice question is also a navigation drill.
3.Track your weak areas: After every quiz and simulation, log the articles you got wrong. Spend the next day reviewing them.
4.Simulate real exam conditions: In Week 4, run simulations in a quiet room with no phone, a strict timer, and only your NEC 2026 and calculator.
5.Use the Master Electrician Practice AI Tutor: When a code requirement doesn't click, ask the AI Tutor to explain it in plain language.

Frequently Asked Questions

Is the 30-day Texas master electrician study checklist really enough to pass?▼

The 30-day checklist is designed for focused, intensive preparation. It works best for candidates who already hold a Texas journeyman license (required for at least two years before you can sit for the master exam), have documented their 12,000 hours of on-the-job training under a Texas-licensed master electrician, and are comfortable reading the NEC. If you are starting from zero, consider combining this plan with an 8–12 week study timeline using the Master Electrician Practice adaptive platform to build baseline knowledge before the 30-day sprint.

Which exam does this checklist cover?▼

It covers both separately scored portions of the Texas Master Electrician exam administered by PSI for TDLR: the NEC Knowledge portion (TX-MST-KNOW — 75 items in 150 minutes: 70 scored + 5 unscored pretest) and the Calculations portion (TX-MST-CALC — 33 items in 170 minutes: 30 scored + 3 unscored). Both are open book with the NEC 2026, and both require a 70% score on the scored items to pass.

Which code book and edition do I need?▼

The reference code book at the Texas test center is the National Electrical Code (NEC) 2026 edition — Texas adopted it effective September 1, 2026. Bring a soft-bound NEC 2026 with manufacturer tabs installed — tabbing is permitted. You may also bring a non-programmable calculator for the Calculations portion.

How many hours per day should I study?▼

Most master candidates should plan for 2–4 hours of focused study per day. Some days in Weeks 1 and 2 (NEC Knowledge) may require 3–4 hours for code reading, while Weeks 3 and 4 focus more on active practice (calculation drills and timed simulations). Consistency matters more than cramming — study every day, even if only for 90 minutes.

Can I print the checklist?▼

Yes! The print view uses a clean white background with black text for easy reading and checkmark tracking. You can also get the free PDF by entering your email in the signup form at the top or bottom of this page.

What if I miss a day?▼

Don't panic. The 30-day plan is a guide, not a rigid requirement. If you fall behind, combine lighter days or extend the plan by a few days. The key is to maintain momentum — completing Weeks 3 and 4 (calculations practice and full simulations) is critical for exam readiness. Use the Master Electrician Practice AI Tutor to catch up on missed topics quickly.
