What Is the ISA Tree Risk Assessment Qualification (TRAQ)?

The International Society of Arboriculture (ISA) offers TRAQ as an instructor-led credential that demonstrates professional knowledge in tree risk assessment through participation in a training course and passing its accompanying exam. The TRAQ program offers tree care professionals the opportunity to expand their knowledge of the fundamentals of tree risk assessment by learning a standardized, systematic process for assessing tree risk and providing information to tree owners and risk managers for making informed decisions that will promote the safety of people and property and enhance tree benefits, health, and longevity.


The course content is based on ISA’s Tree Risk Assessment Manual and is divided into nine modules:

1.   Introduction to Tree Risk Assessment
2.   Levels of Assessment
3.   Target Assessment
4.   Site Assessment
5.   Tree Biology and Mechanics
6.   Tree Inspection and Assessment
7.   Data Analysis and Risk Categorization
8.   Mitigation
9.   Reporting

Continuing Education Units (CEUs) for ISA Certification Holders 

If you hold an ISA certification, you can earn 14.5 ISA CEUs if you complete the ISA Tree Risk Assessment course, attending at least 80 percent of the instructional portion of the program. These CEUs can be applied to your ISA Certified Arborist® credential, including the Tree Worker credentials. For an ISA Board Certified Master Arborist®, 6 CEUs go to practice, 6 to management, and 2.5 to science.

What Are the Course Objectives?

•   Comprehension of the fundamentals of limited-visual and basic tree risk assessment as defined in the ISA Best Management Practices: Tree Risk Assessment;
•   Knowledge of the principles of advanced diagnostic techniques for assessing tree risk;
•   Mastery of methods for gathering and evaluating information to assess tree risk;
•   Development of reasoned judgments and recommendations for mitigating identified risk.

How Are the TRAQ Course and Exam Presented?

The standard ISA TRAQ course is a two-day, in-person training course followed by a half-day examination. (Instructors may extend the time/length of the course in specific circumstances.) Lectures, discussions, small-group activities, applied case studies, and field activities are all a part of the training process. The examination consists of two parts:

• Written exam: 100 multiple-choice questions. Each question has four answer choices, and only one is correct. You will have two hours to complete the written exam.
• Performance-based exam: An actual, outdoor tree assessment will test your ability to apply tree risk principles to a tree at the training site. You will have one hour to complete the performance-based exam.
