How do you become a certified arborist?

Certified arborists have additional training and experience that set themselves apart from other tree consultants. Most have earned a degree in the field of arboriculture, horticulture, landscape architecture, or forestry from a regionally accredited educational institute. Organizations such as the ISA provide rigorous training and guidelines for certification that include one to three years of experience, depending on formal education level, and adherence to a strict code of ethics.
