ISA Certification is a voluntary program that tests and certifies your achievement of a professional level of knowledge and skill in the field of arboriculture. When you become an ISA Certified Arborist®, you are recognized by your peers and the public as a tree care professional who has attained a generally-accepted level of knowledge in areas such as tree biology, diagnosis, maintenance practices, safety, and other subject and practice areas within the tree care profession as identified through periodic job task analyses. Hiring a Certified Arborist provides tree owners and government decision makers the opportunity to become better informed about proper tree care and their selection of services based on the expertise represented by your credential.
Achieving ISA Certification also builds your self-image. By studying for and passing the certification exam, you demonstrate a dedication to your own professional development and the advancement of proper tree care practices. The process of becoming ISA Certified and maintaining the designation provides you with personal incentive to continue your arboricultural education and training. Presenting your ISA credential to potential employers makes you more competitive in the job market, and for employers, encouraging ISA Certification is a tool to assist in training their existing tree care personnel.
