Take your pruning knowledge beyond “where to cut” and learn how to build a true pruning prescription.
ISA Michigan is bringing the Prescription Pruning Qualification Course to Wixom, Michigan, October 27–29, 2026, taught by Dr. Edward F. Gilman and Nick Markley.
This practical, applied program teaches arborists how to strategically plan, specify, and implement objective-based pruning using industry standards, ISA Best Management Practices, current research, and real-world application.
The goal is simple: improve communication between the person prescribing the pruning, the production arborist completing the work, and the tree owner — while creating clearer, more consistent work orders and pruning outcomes.
Participants can choose from two training tracks:
Day 1 – Producers
Open to arborists and others involved in pruning work. Spend the day learning tree architecture, tree response to pruning cuts, and how to guide urban-compatible tree structure. Producers receive a certificate of completion. ISA Certification is not required.
Days 1–3 – Prescribers
Designed for ISA Certified Arborists who want to take the process further by learning how to prepare pruning prescriptions. Days 2 and 3 include prescription development, outdoor exercises, discussion, review, and an exam. Those who pass become PPQ qualified.
The program is especially valuable for arborists who prune trees, prescribe pruning, prepare work orders, or manage pruning contracts.
