EQUINE Facilitated Interactions (EFI), sometimes referred to under the wider definition Equine Assisted Services (EAS), is an umbrella term that describes the increasingly recognised benefit of facilitated interactions between humans and horses (or other equids such as donkeys) with the purpose of providing individual learning and development, or deeper therapeutic healing.

These interactions are often referred to more specifically in terms of the primary scope of practice and qualifications of the facilitator such as Equine Facilitated/Assisted Learning, or Equine Facilitated/Assisted Therapy or Psychotherapy. For example, one has to be a qualified therapist to practice therapy alongside horses.
