When a professional becomes an ISA Certified Arborist, they should be recognized by their peers and the public as a tree care professional who has attained a generally-accepted level of knowledge in core and broad areas of arboriculture field as identified through periodic job task analyses.  \nDomains  \nDomains are the major responsibilities or duties that characterize the practice of arboriculture. The weight or percentages denote the amount of the exam that is devoted to each domain.  \n• Tree Biology (11%)  \n• Tree Identification and Selection (9%)  \n• Soil Management (7%)  \n• Installation and Establishment (9%)  \n• Pruning (14%)  \n• Diagnosis and Treatment (9%)  \n• Trees and Construction (9%)  \n• Tree Risk (11%)  \n• Safe Work Practices (15%)  \n• Urban Forestry (6%)  \nTree Biology Weight: 11%  \nTask A: Specify and recommend tree work based on knowledge of tree anatomy, physiology, and biomechanics.  \nKnowledge of: Skill in:  \n1. Root anatomy and functions  \n2. Trunk, branch, twig, and leaf anatomy and functions  \n3. Respiration, photosynthesis, and energy allocation and storage within the tree  \n4. Water movement within the tree (i.e., root uptake, transpiration, and water transport structures)  \n5.
