TRAQ Certification

The TRAQ certification is the newest certification available in the arboriculture field. It was developed by the Tree Risk Assessment Qualifications Board (TRAAQB) to meet the needs of those who work in the field of tree risk assessment. The TRAQ certification requires at least one year of experience and a degree or certificate in forestry or forestry-related studies.

The purpose of this certification is to provide a level of training that will allow arborists to work independently as tree risk assessors. It is designed to be less comprehensive than other certifications like the Certified Arborist (CA) and Certified Consulting Arborist (CCA).
