Credentials

Maintaining Your Credentials

All ISA Certifications are valid for three years. To maintain your certification, you must earn a minimum number of ISA Continuing Education Units (CEUs) by the end of the three-year period and pay a recertification fee. Or, you can retake and pass the exam. The number of CEUs required depends upon the credential you hold:

  • ISA Certified Arborist: 30 CEUs
  • ISA Certified Arborist Utility Specialist: 6 Utility CEUs + 30 Arborist CEUs = 36 total
  • ISA Certified Arborist Municipal Specialist: 12 Municipal CEUs + 30 Arborist CEUs = 42 total
  • ISA Certified Tree Worker Climber Specialist: 15 CEUs
  • ISA Certified Tree Worker Aerial Lift Specialist: 15 CEUs
  • ISA Board Certified Master Arborist: 60 CEUs; 20 each in Science, Practice, and Management

The TRAQ credential is valid for five (5) years from the date it is earned. A credential holder is required to take the TRAQ Renewal Course and pass the exam every five (5) years in order to renew the credential. No CEUs are needed to maintain this qualification. However, ISA certification holders will be offered 14.5 CEUs for attending the full course and 5 CEUs for attending the Renewal Course.

Recertification Fees

Your renewal date will be on June 30 or December 31, depending on the date of your original certification exam. Notification of your renewal date will be mailed one month in advance. Please make sure your contact information is current to ensure delivery of any mailed notices.

Retaking the Exam

If you do not meet minimum CEU requirements and/or pay the renewal fee, you must retake the certification exam and pay appropriate fees to recertify. Be sure to include your previously assigned ISA Certification number on the application to ensure the number is reassigned to you.

Only bona fide ISA credential holders are eligible to advertise ISA credentials. Until you have successfully passed the exam, you should refrain from advertising yourself as ISA Certified so as to not mislead the public and violate federal trademark law. Refer to ISA Ethics and Integrity for more information.

Need CEUs?

CEUs can be earned through a variety of continuing education and training opportunities. There are many other arboriculture resources through which CEUs can be earned. ISA encourages active participation in Chapters, Professional Affiliations, and Associated Organizations.

Tracking Your CEUs

ISA will track how many CEUs you have and how many you need for renewal. You may also check your CEUs status here.
