New to Cathodic Protection
Start with the basic corrosion cell, anodes and cathodes, electrolyte paths, protective current, and why CP changes structure-to-electrolyte potentials.
Cathodic protection learning for field work and study
Learn cathodic protection through formulas, field examples, technical guides, and certification-style practice.
Cathodic Academy organizes CP measurements, criteria, calculations, survey methods, system behavior, and troubleshooting into practical learning paths. Start where you are: beginner concepts, certification study, field testing, formulas, or data interpretation.

Where should I start?
Studying for Certification
Follow CP 1 through CP 4 study pages, then use practice questions and quizzes to check weak spots before reviewing deeper references.
Need a Formula
Find CP calculations with variable definitions, units, worked examples, and field interpretation notes.
Doing Field Testing
Use Technical Practice Guides for survey setup, valid data conditions, common mistakes, and interpretation logic.
Interpreting Measurements
Understand what a reading means, what current condition produced it, and what can make it misleading.
Practice Questions and Quizzes
Use static practice questions for careful review and randomized quizzes for faster self-checking.
Built for practical CP learning
Field measurements, criteria, formulas, and standards-aware explanations in one place.
The site is designed for CP learners, field technicians, inspectors, engineers-in-training, and certification candidates who need more than definitions. Pages connect readings to current condition, reference electrode placement, IR drop, current distribution, criteria, and common field mistakes.
Cathodic Academy is an independent educational resource. It supports learning and interpretation, but it does not replace official standards, employer procedures, project specifications, site safety requirements, or qualified professional judgment.

Why CP stops feeling like black magic
Everything has to balance.
Cathodic protection is physics and chemistry. Current must complete a path. Electrons moving through metal are paired with ionic activity in the electrolyte. A formula is not just math; it shows which variables must balance for the system to behave the way it does.
Use formulas and quizzes first if that helps you find your weak spots. Then follow the related measurements, criteria, and system pages to understand why the result occurs.
