ISA Tree Risk Assessment Qualification (TRAQ)

The ISA Tree Risk Assessment Qualification (TRAQ) programme provides an opportunity for professionals in the arboriculture industry to expand their knowledge through education and training in the fundamentals of tree risk assessment. This qualification promotes the safety of people and property by providing a standardised 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.

The Tree Risk Assessment Qualification course is a two-day educational course followed by a half day assessment that includes both a written and field component. The course prepares the participant to take the TRAQ assessment to become ISA Tree Risk Assessment Qualified. Participant is required to attend the course and successfully complete the assessment in order to receive this qualification.

Qualified professionals will be:

  • proficient with the fundamentals of limited visual and basic tree risk assessment
  • understand the principles of advance diagnostic techniques for assessing tree risk
  • gather and synthesize information needed to assess tree risk
  • make reasoned judgements and recommendations for mitigating identified risk
Tree Biology and Mechanics:
Participants will learn how to assess wood structure, decay and tree mechanics, and evaluate their impact on likelihood of tree or tree part failure. Participants will also learn how to identify and assess defects and conditions that may affect likelihood of failure.

Tree Inspection and Assessment:
Participants will learn about types of targets, assess the likelihood of a tree or tree part impacting a target, and estimate the consequences of tree or tree part failure. Participants will also learn how to assess site factors that may influence likelihood of failure.

Data Analysis and Risk Categorization:
After learning the tree and target factors that must be assessed, participants will combine likelihood of failure, likelihood of impact, and consequences of failure to derive a risk rating. This rating helps the assessor communicate tree risk to clients and risk managers, and allows comparison of risk levels between trees.

Risk Reporting:
Participants will learn skills for clearly communicating tree risk to clients, both in written and verbal reports. Participants will also learn about the key components that should be included in a report after completing a tree risk assessment.

To be able to register for the course and take the exam, applicants must have earned at least one of the following credentials:

  • ISA Certified Arborist
  • ISA Board Certified Master Arborist
  • An arboriculture or urban forestry degree that is part of a national qualification framework or is from a college or university that is accredited or recognized under a system that is substantially similar to accreditation
