An Arborist by definition is an individual who is trained in the art and science of planting, caring for, and maintaining individual trees.

​

Certified Arborists are individuals who have achieved a level of knowledge in the art and science of tree care through experience and by passing a comprehensive examination developed by some of the nation’s leading experts on tree care. Certified Arborists must also continue their education to maintain their certification. Therefore, they are more likely to be up-to-date on the latest techniques in Arboriculture.

​

 ISA Arborist Certification is a nongovernmental, voluntary process by which individuals can document their base of knowledge. It operates without mandate of law and is an internal, self-regulating device administered by the International Society of Arboriculture. Certification provides a measurable assessment of an individual’s knowledge and competence required to provide proper tree care.

​

The International Society of Arboriculture (ISA) was founded in 1924 and has served the tree care industry for over seventy years as a scientific and educational non-profit organization. ISA supports tree care around the world and is dedicated to the care and preservation of shade and ornamental trees. This organization continues to be a dynamic medium through which arborists around the world share their experiences and knowledge for the benefit of society. Aligned on many fronts with other green organizations, ISA is working hard to foster a better understanding of trees and tree care through research and the education of professionals as well as global efforts to inform tree care consumers.
