Industry Terms

Animal-Assisted Intervention (AAI)

Animal-assisted interventions are goal-oriented and structured interventions that intentionally incorporate animals in health, education, and human service for the purpose of therapeutic gains and improved health and wellness. Animal-assisted therapy (AAT), animal-assisted education (AAE), and animal-assisted activities (AAA) are all forms of animal-assisted interventions. In all these interventions, the animal may be part of a volunteer therapy animal team working under the direction of a professional or an animal that belongs to the professional himself.

Animal-Assisted Therapy (AAT)

Animal-assisted therapy is a goal-oriented, planned, structured, and documented therapeutic intervention directed by health and human service providers as part of their profession. A wide variety of disciplines may incorporate AAT. Possible practitioners could include physicians, occupational therapists, physical therapists, certified therapeutic recreation specialists, nurses, social workers, speech therapists, or mental health professionals.

Animal-Assisted Education (AAE)

Animal-assisted education is a goal-oriented, planned, and structured intervention directed by a general education or special education professional. The focus of the activities is on academic goals, prosocial skills, and cognitive functioning with student progress being both measured and documented.

Animal-Assisted Activities (AAA)

Animal-assisted activities provide opportunities for motivational, educational, and/or recreational benefits to enhance quality of life. While more informal in nature, these activities are delivered by a specially trained professional, paraprofessional, and/or volunteer, in partnership with an animal that meets specific criteria for suitability.

*The terms AAI, AAT, AAE, and AAA are the preferred industry terms. The term ‘pet therapy’ should be avoided because it is inaccurate and misleading. The term was widely used several decades ago to refer to animal training programs. By contrast, the currently preferred terms imply that the animal is acting as a motivating force to enhance the treatment provided by a well-trained person.

Therapy Animal

Therapy animals, such as those who participate in the Pet Partners Therapy Animal Program, provide affection and comfort to members of the public, typically in facility settings such as hospitals, assisted living, and schools. These pets have a special aptitude for interacting with members of the public and enjoy doing so. Therapy animal handlers volunteer their time to visit with their animals in the community.

A therapy animal has no special rights of access, except in those facilities where they are welcomed. They may not enter businesses with “no pets” policies or accompany their handler in the cabin of an airplane regardless of their therapy animal designation.

Assistance Animal (also commonly called Service Animal)

Assistance animals are defined as dogs and in some cases miniature horses that are individually trained to do work or perform tasks for people with disabilities. Examples include guide dogs for people who are blind, hearing dogs for people who are deaf, or dogs who to provide mobility assistance or communicate medical alerts.

Assistance dogs are considered working animals, not pets. The work or task a dog has been trained to provide must be directly related to the person’s disability. Guide, hearing, and service dogs are permitted, in accordance with the ADA, to accompany a person with a disability almost anywhere the general public is allowed. This includes restaurants, businesses, and on airplanes.

Emotional Support Animal

An emotional support animal, sometimes also referred to as a comfort animal, is a pet that provides therapeutic support to a person with a mental illness. To be designated as an emotional support animal, the pet must be prescribed by a licensed mental health professional for a person with a mental illness. The prescription must state that the individual has an impairment that substantially limits one or more major life activities, and that the presence of the animal is necessary for the individual’s mental health.

Per the ADA, individuals with emotional support animals do not have the same rights to public access as individuals with a service dog. Emotional support animals may only accompany their owners in public areas with the express permission of each individual venue and/or facility management. Emotional support animals may live with their owners in locations covered by the Fair Housing Amendments Act (FHAA) regardless of a “no pets” policy, and may travel with their owners on airplanes with documentation as required by the airline. Although most frequently dogs, other species may be prescribed as emotional support animals.

Facility Animal

A facility animal is an animal who is regularly present in a residential or clinical setting. These animals may be a variety of species from dogs and cats to birds and fish. They might live with a handler who is an employee of the facility and come to work each day or they might live at the facility full time under the care of a primary staff person. Facility animals should be specially trained for extended interactions with clients or residents of the facility, which may include AAA, AAE, or AAT. These animals do not have special rights of access in public unless they are accompanying and directly supporting a client with a disability.

Pet Partners Terms


The process through which a therapy animal team becomes part of the Pet Partners Therapy Animal Program. This process confirms that the team meets the requirements of our program and is suitable to participate in AAI. There is a distinction between registration and certification. Therapy animal teams are registered, not certified. Certification implies that an independent third party has assessed an individual’s mastery of knowledge and skills. For example, a doctor is certified by a Board of Medicine, not the medical school where they completed their education. At this time, no independent certifying bodies for therapy animals exist.

Therapy Animal Team

A unique combination of one handler and one animal working together that registers through Pet Partners to participate in volunteer AAI in their community. Because Pet Partners believes in the importance of proactive handling both for animal welfare and client safety reasons, we emphasize the importance of balance between a skilled handler, an appropriate animal, and a positive, communicative relationship between the two. Our registration process is designed to assess this through a combination of coursework and evaluation.
