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 qualification consists of a two-day educational course followed by a half-day assessment that includes both a written and a field component. You must attend the course and successfully complete the assessment in order to receive this qualification.

To support reliable and consistent delivery of program resources, promote fairness and impartiality, and reduce ISA's carbon footprint, candidates approved for the ISA TRAQ Program will no longer automatically receive printed materials by mail. Instead, all participants will be provided digital access to the material required to prepare for the program. 

When applying to participate in a TRAQ event, applicants must agree to the terms, conditions, and policies.
