Horsemanship is the human practice of working with horses, from routine handling and training to ridden work, and in welfare science it denotes the quality of that practice as judged from the horse's behavioural and physiological responses [1][2]. It is relational rather than a property of the handler alone: the human–horse relationship emerges from repeated interactions, and the incidence of horse-related accidents depends more on the frequency and amount of contact than on the level of competence [3]. Owner knowledge and experience shape attitudes and management behaviour, which in turn affect welfare [4]. In ridden work, more skilled riders achieve better gait quality, yet behavioural pain markers do not differ consistently with rider skill [2].
