ISA Utility Specialist case studies
ISA Utility Specialist · Put your knowledge to work in context.
The ISA Certified Utility Specialist credential is a specialty certification for arborists and vegetation managers who work on or around electric utility rights-of-way. It signals that the holder understands the unique blend of arboriculture, regulatory compliance, safety, and program management that utility vegetation management demands. The exam is intended for practitioners such as utility foresters, vegetation management coordinators, contract supervisors, and consulting arborists who already hold the ISA Certified Arborist credential and want to demonstrate advanced, utility-specific competence. Content spans program administration and planning; human resources, safety, and training; budgeting and work planning; regulations and standards such as NERC FAC-003, ANSI A300, and OSHA; tree biology and growth response to utility pruning; pruning practices and clearance standards; integrated vegetation management and herbicide use; and public and landowner relations. The ISA Utility Specialist case studies are 5 cases and about 2,993 words.
