Becoming Qualified

The ISA Certification Program has led the way as a credentialing body in the arboricultural industry for many years. In order to meet the needs of the profession and respond to the demands of the stakeholders for advanced certificate-based programs, ISA has expanded its training and credentialing opportunities to include qualifications.

When thinking about which credential is essential to your career, it is important to understand the difference between a certification and qualification. Certification is a voluntary process by which individuals are tested on a body of knowledge gained from training and/or experience. Testing is designed to demonstrate individuals have met predetermined and standardized criteria and maintenance requires continuing education units. Qualifications include a specifically designed learning event followed by an assessment to confirm individuals have achieved the intended learning outcomes. Learn more about the difference between Certifications and Qualifications.

Tree Risk Assessment Qualification

TRAQ is an ISA qualification program that trains arborists how to use the methodologies outlined in the ISA Best Management Practices for Tree Risk Assessment. This qualification promotes the safety of people and property by providing a standardized and systematic process for assessing tree risk. The results of a tree risk assessment can provide tree owners and risk managers with the information to make informed decisions to enhance tree benefits, health, and longevity.
