    This is a 3-day course which includes two days of training and demonstrations culminating in an exam. The successful candidate will receive the Prescription Pruning Qualification being recognized nationwide. You must be an ISA Certified Arborist to attend the qualification course. However, it is not required to attend DAY ONE ONLY.

    This new pruning paradigm shifts the decision of which branches to prune from the production arborist to an informed prescriber. It establishes a protocol resulting in consistency between the arborist preparing the prescription and the production arborist. This credential teaches you how to prescribe and perform pruning in accordance with industry standards and ISA’s BMP, which is supported by the latest research and experience.

    All PRESCRIBER registrations will be reviewed to verify the prerequisite. Before the event, registrants will be emailed a link to the PPQ Manual to study. A hard copy will be given during check-in at the event. Cancellation refunds are available up to 7 working days before the event. Attendee substitutions will be honored for Day 1 ONLY.

    Instructors:

    Lindsey Purcell, Consulting Arborist, LP Consulting Group
