Certified Master Arborist Exam The Certified Master Arborist exam assumes you’ve logged at least three years of documented tree care experience and passed the ISA Certified Arborist credential first. Without foundational knowledge of phytopathology, entomology, and soil chemistry, you’ll struggle through sections on integrated pest management and root health diagnostics. Expect questions demanding practical field judgment alongside theoretical rigor.
