About the Certified Arborist Program 

ISA Arborist Certification is a non-governmental, voluntary process by which individuals can document their base of

knowledge.  Certification provides a measurable assessment of an individual’s knowledge and competence required to provide proper tree care.

Certification is not a measure of standards of business practice.  It can only attest to the tree knowledge of an individual, and cannot guarantee or assure quality performance.  This booklet is to serve as a directory only and not as a recommendation of any company in the Illinois Arborist Association. 

Certified Arborists are individuals who have achieved a level of knowledge in the art and science of tree care through at least three years experience and have passed 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 status as an ISA Certified Arborist.  This ensures that the latest information, techniques and research in arboriculture is always updated and made available to the arborist.
