TPAQ Instructor Training

In 2018 ASCA announced the launch of the Tree and Plant Appraisal Qualification (TPAQ). Designed as an instructor-lead program, the goal of TPAQ is to help industry professionals advance their knowledge of the theory and application of appraisal approaches, methods, and techniques using The Guide to Plant Appraisal 10th edition as the text for the program.
