What is the TPAQ Program?
The Tree and Plant Appraisal Qualification (TPAQ) program, developed by the American Society of Consulting Arborists (ASCA), is an interactive training experience that delves into the concepts contained in the 10th edition of the Guide for Plant Appraisal. Using instructor-led discussions and case scenarios to illustrate concepts, you will become proficient in conducting appraisals using the various approaches contained in the guide.

The training culminates with an open-book exam that tests attendees on their comprehension of the material and concepts. Successful candidates will receive a certificate and be entitled to list TPAQ as a credential.

Modeled after the ISA’s Tree Risk Assessment Qualification (TRAQ), the course features cooperative argumentative dialogue between the instructor and course participants, to stimulate critical thinking and to draw out ideas and underlying presuppositions. ISA TRAQ and/or certified arborist credentials along with prior experience in plant or other appraisal techniques (assigning dollar values) are strongly encouraged but are not a requirement. Participants must have and read the 10th edition Guide to Plant Appraisal prior to attending the class.
