Certified Arborists

Anybody that works in the arborcultural industry can refer to themselves as an arborist. They are not required to have any education or pass any exams. ISA Certified Arborists are individuals who have achieved a level of knowledge in the art and science of tree care through at least three years of experience and have passed a comprehensive examination. They are also required to continue their education in order to maintain their certification, ensuring their knowledge is updated on the latest arboriculture techniques. ISA Arborist Certification is a non-governmental voluntary process that operates without mandate of law. It is an internal self-regulating device administered by the International Society of Arboriculture, and therefore, cannot guarantee or assure the quality of performance. Certification provides a measurable assessment of an individual's knowledge and competence required to provide proper tree care.
