What is ISA Certification?
Certification is a voluntary program providing recognition of one's professional knowledge by one's peers. International Society of Arboriculture (ISA) Certified Arborist recognition is given by the ISA to those who (1) meet the eligibility requirements for admission to the examination as set forth in this application, (2) successfully complete the examination, and (3) maintain the necessary number of continuing education units to recertify after three years.
The objectives of the Certification Program are:
- To be an educational program that will improve technical competency of personnel in the tree care industry.
- To create incentives for these individuals to continue their professional development.
- To provide the public and those in government with a means to identify those professionals who have demonstrated, through a professionally developed exam and education program, that they have a thorough knowledge of tree care practices.
The benefits of the Certification Program include the following:
- Certification builds an individual’s self-image. By studying for and passing the exam, individuals reaffirm to themselves and their peers a thorough knowledge and dedication to arboriculture.
- Certification affords the public and those in government the opportunity to make an informed selection of services based on the knowledge that is represented by the certification designation.
- The process of becoming certified and maintaining the designation provides incentives to the individual to continue his or her ongoing professional development.
- Certification is a tool to help employers both in training their personnel and selecting new employees.

The Arborists’ Certification Study Guide is intended to serve as a recommended program of study. Each chapter in the study guide lists additional references that should be considered for review, such as Arboriculture: Integrated Management of Landscape Trees, Shrubs and Vines (Harris, Clark, and Matheny); Tree Maintenance (Pirone); New Tree Biology (Shigo); the AS4373-1996 Pruning of Amenity Trees; Horticopia Arborist Edition; and Trees, Shrubs and Groundcovers Edition II.
