Western Chapter ISA Certified Tree Workers are individuals who have a minimum of 18 months experience professionally climbing
trees in a safe and efficient manner to perform tree care. They have knowledge in the major aspects involved in tree care including,
tree biology, cabling, planting, pruning and safety. Applicants are required to complete a written knowledge based exam and a practical
skills evaluation which includes knot tying. Skills evaluations are conducted in either climbing or aerial lift operations.
NOTE: THE WESTERN CHAPTER’S CERTIFIED TREE WORKER PROGRAM IS INDEPENDENT OF THE ISA’S CREDENTIAL.
