New Qualification: Tree Risk Assessment

The ISA Certification Program has led the way as a credentialing body in the arboricultural industry for many years. In order to meet the needs of the profession and respond to the demands of our stakeholders, we are now exploring new opportunities with qualifications. While qualifications are more well known outside of the United States, as an international organization, ISA is looking to expand training and credentialing opportunities with this new initiative. Qualifications, much like certifications, promote professional development and help set you apart from the competition. But when thinking about which credential is essential to your career, it is important to understand the difference between a certification and qualification.

The first Qualification that ISA plans to launch is on the topic of Tree Risk Assessment. Working with an international panel of experts, ISA is currently developing the qualification and will keep you posted on its availability. For more information on ISA's new program and the transition from the Pacific Northwest Chapter TRACE program expand this section.

Revised CTW Program Proposal

The Credentialing Council has formed a committee to enhance and improve the current Certified Tree Worker (CTW) program based on the current program’s poor response and feedback from tree workers, employers, Certified Arborists and Chapter Liaisons. This communication is meant to provide you with some information on the direction this committee is taking for their program proposal. If you have questions or feedback, contact information has been provided at the bottom of the communication.
