The scope of Animal Assisted Interventions spans several interdisciplinary areas. AAII has outlined membership categories in an effort for better inclusion and representation of what our members have explained that they do, and how different work in AAIs is categorized around the world. We understand that there are variations in the requirements or prerequisites for ones’ professional or volunteer representation, for example, in some regions, a social worker is considered ‘therapy’ and in another region it is not. The addition of several new categories speaks to those differences. It is very possible that an individual or organization may belong to more than one membership category. Please carefully review the descriptions and criteria for each category before applying for your membership.
