The document discusses developing quality criteria and impact models for social pedagogical equine-assisted interventions in Finland. There are three main types of these interventions that are offered by professionals to support social growth and well-being through human-horse interaction and social pedagogy. Quality criteria were defined that address the professional competence of instructors, implementation of social pedagogy, defining and monitoring customer goals, safety, and more. An impact model was also created that combines these quality criteria with an impact chain to allow instructors to exemplify possible outcomes and impacts of their specific services. Future research may examine data from these impact models to help choose suitable measuring instruments for intervention studies.
