What is the difference between an arborist and a certified arborist?

A: Arborists are trained professionals that are knowledgeable and equipped to provide proper tree care. They are specially trained to provide a variety to services to maintain trees. 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.
