Online Learning and CEU Opportunities
Webinars and webcasts can be an opportunity to learn (and earn CEUs) from anywhere. Many organizations offer monthly free or paid live and on-demand webinars, covering a variety of topics helpful for arborists and urban foresters.
For webinars that do not offer pre-approved ISA CEUs, but that cover content in the ISA exam domains, you can apply for post-approval credit.
Many organizations are adding more webinars to their offerings. Check the websites below for dates, times, and CEU information and check our calendar for specific opportunities.
