In 2021, the HETI Terminology task force conducted a survey to establish acceptable terms that HETI can use in all of its communications. The accepted terms were:

Equine Assisted Services (EAS)
Service Provider (SP)
Service User (SU)

Details about this survey can be found in this Press Release

Following this, the task force published a study based on the results of a global survey on terminology within Equine Assisted Services. This paper can be purchased here  or HETI members can download the paper for free here.
