Instructor support

Every unit opens with an instructor panel. Ask a question and the answer is grounded in that unit's text and cited back to it — the same way an instructor points you to the code article instead of guessing. Diagrams are drawn on request.

It tracks the topics you keep missing and drills them, runs timed exam simulations under real time pressure, takes voice questions and photos of your work, and teaches in Spanish.

Career prep, not a license.

Fieldora Academy provides exam preparation and trade education. Completion does not grant a state license and is not a substitute for required apprenticeship hours or board-administered exams. Always verify current requirements with your state licensing authority before you sit for an exam or accept work.
