For over 100 years, ISA has been dedicated to advancing arboriculture by supporting the professional development and expertise of practitioners across the globe. To carry forward this commitment another century, ISA will launch a newly updated credentialing system and pricing structure on 15 July 2025.

What's Changing?

Our new credentialing system and pricing structure are designed to:

• Streamline the credentialing and recertification process;
• Enhance multilingual and mobile accessibility;
• Provide fair, transparent pricing with standardized 20% discounts for both ISA members and credential holders; and
• Ensure fees are reflective of the full spectrum of Credentialing Services provided by ISA.

Temporary Credentialing System Web Outage

To make way for the new system, ISA have a planned web outage from 7-14 July 2025. During this time, the following Credentialing Services will be impacted: 

• CEU management and upload;
• Application submission; and
• Examination enrollment.
