We are building the most effective study platform for the master electrician exam in all nine states we serve — Texas, Colorado, New Hampshire, Vermont, Maine, Delaware, Arkansas, Kentucky, and Wyoming — combining AI technology with real NEC expertise to help licensed electricians go from journeyman to master with confidence.
Our mission is simple: help every qualified master electrician candidate pass their state's master electrician exam and earn the license that lets them run jobs and own a business — in Texas, Colorado, New Hampshire, Vermont, Maine, Delaware, Arkansas, Kentucky, and Wyoming. We believe preparing for the master exam should not be a guessing game. Too many candidates walk into the testing center unprepared — not because they lack skills, but because they lack study tools that reflect the true open-book exam experience.
Traditional study materials for electrical exams are outdated, difficult to navigate, and rarely offer the depth of official-blueprint practice needed to build real confidence. The National Electrical Code is dense, realistic practice questions are scarce, and its chapter-and-article structure can feel overwhelming without a structured approach. The code edition matters too: Texas and Colorado test against NEC 2026, while the other seven states we serve — New Hampshire, Vermont, Maine, Delaware, Arkansas, Kentucky, and Wyoming — test against NEC 2023. We set out to change that by building a platform that adapts to each candidate's learning pace, identifies weak points, and offers targeted practice where it matters most — from service and feeder sizing to the Article 310 ampacity tables that anchor the Texas Calculations portion.
At the heart of our mission is a commitment to safety. Every master electrician who signs off on a job is responsible for the people who will live and work in the buildings they wire. By ensuring that license candidates are thoroughly prepared to apply the NEC correctly, we are contributing to safer electrical installations across all nine states we serve.
Master Electrician Practice is not a simple flashcard app. It is a specialized, AI-powered study platform engineered from the ground up around the official master electrician exam blueprints of nine state licensing boards. In Texas, candidates sit two separately scored exams — NEC Knowledge (TX-MST-KNOW, 75 items in 150 minutes — 70 scored plus 5 unscored pretest) and Calculations (TX-MST-CALC, 33 items in 170 minutes — 30 scored plus 3 unscored), both open-book against the NEC 2026 at the PSI test center. Colorado candidates take a single Master Electrician exam (90 items in 240 minutes, 70% passing score) on NEC 2026, with the reference NEC provided at the test center. The seven NEC 2023 states — New Hampshire, Vermont, Maine, Delaware, and Arkansas, whose boards license masters directly, plus Kentucky and Wyoming via the ICC 701 route — each run a single master exam through their board's testing vendor. Every question, every explanation, and every algorithm is designed to reflect the true exam experience at your state's testing center.
Our practice content is generated and reviewed against each state board's official blueprint — in Texas, the ten NEC Knowledge subject areas and the ten Calculations subject areas with their real weights, and in the other eight states, the blueprint subject areas set by that state's board or, for Kentucky and Wyoming, the ICC 701 standard. Every question is tagged by subject area, NEC article, topic, difficulty level, and exact code reference — making it easy for candidates to target their weak areas and train their code-navigation speed.
The AI adjusts question difficulty in real time based on your performance. Master a topic and the system challenges you further; struggle and it offers more foundational exercises. This ensures efficient, targeted study sessions.
Timed practice exams replicate the real open-book testing environment for your state: the separate NEC Knowledge and Calculations portions that Texas candidates take, or the single comprehensive exam format used in Colorado and the other seven states — each with its real item counts and time limits. Build code-navigation speed and confidence before exam day.
Get instant, plain-language explanations of complex NEC requirements. Ask questions naturally and receive exam-focused answers that reference the exact articles and tables.
Detailed analytics show your performance in every NEC chapter and calculation area. Track accuracy by article, monitor difficulty progression, and review your exam history — always know exactly where you stand.
Programmer & AI Specialist — Founder of Master Electrician Practice
Chuck Onekeo is a programmer and AI specialist with extensive experience building intelligent systems for technical education. Frustrated by the lack of modern, adaptive study tools available to electrical license candidates, Chuck decided to build the platform he wished he had when preparing for his own technical exams.
Combining his expertise in artificial intelligence, machine learning, and full-stack development, Chuck designed Master Electrician Practice from the ground up as an adaptive learning system tailored specifically to the open-book NEC master exams of the nine states we serve. The platform's AI engine dynamically adjusts question difficulty, generates contextual explanations, and provides personalized study recommendations based on individual performance.
Chuck's vision for Master Electrician Practice goes beyond helping candidates pass their exams. He believes that well-prepared electricians complete safer, code-compliant installations, and that technology — especially AI — has the power to dramatically improve how electrical professionals prepare for high-stakes license exams.
The path to a master license is demanding in every state we serve. Texas shows how much is at stake: candidates must hold a journeyman license for at least two years, document 12,000 hours of on-the-job training under a Texas-licensed master electrician, and then master the National Electrical Code across its nine chapters, pass two timed, open-book, code-navigation portions, and develop the tab-flipping speed that makes the difference on exam day. Despite the high stakes — Texas sees roughly 7,400 master exam attempts a year with a pass rate around 19–22% — most candidates rely on dense manuals, scattered PDFs, and word-of-mouth advice to prepare.
The same gap exists for master candidates in Colorado, New Hampshire, Vermont, Maine, Delaware, Arkansas, Kentucky, and Wyoming — candidates whose state boards publish official blueprints but who are left to hunt for practice content that actually matches them. We saw a gap that technology could fill. The same AI techniques that power recommendation systems, language models, and adaptive tutoring platforms could be applied to master exam preparation — and the result is a study experience that is more effective, more engaging, and more performant than anything currently available to master candidates.
Key problems we set out to solve:
We are committed to building a platform that genuinely helps master candidates succeed. That means:
Every question is reviewed against the code edition used by your state's exam — NEC 2026 in Texas and Colorado, NEC 2023 in the other seven states. We regularly update our question bank to stay aligned with current code editions and exam bulletins.
We offer a free tier so every candidate can try the platform, plus affordable monthly, yearly, and lifetime plans. No hidden fees, no surprises.
Our success is measured by your success. We continuously improve the platform based on candidate feedback and performance data to maximize pass rates.
We are just getting started. The platform evolves constantly with new features, more practice content, and improved AI capabilities. Our long-term vision is to become the go-to study resource for master electrician candidates in every state we serve — Texas, Colorado, New Hampshire, Vermont, Maine, Delaware, Arkansas, Kentucky, and Wyoming — supporting electricians at every stage of the licensing ladder, from journeyman to master. Whether you are just beginning your NEC Knowledge review or grinding through service and motor calculations, Master Electrician Practice is built for you.
