The ISA Tree Risk Assessment Qualification (ISA TRAQ) is a voluntary qualification program designed to train and assess candidates in a specialized field of arboriculture—tree risk assessment. The training portion of the program is delivered through credential holders who have gone above and beyond the requirements to earn and maintain this credential and also have extensive experience in the practice of tree risk assessment and facilitation of professional training. Today, we are featuring new Approved Instructors for the program.
