The Tsai Electro founder built the Texas Journeyman practice the way he wishes he had been taught. Practice includes a versioned NEC reference registry, timed navigation drills, worked calculation solutions, and dated correction records. Every answer that relies on the code names its NEC article and section. Every question is checked in a separate review pass, and an outside reviewer has checked Journeyman questions against the printed 2026 NEC. You can report an error from any question.
