In therapeutic riding the lessons are developed around equestrian skill development and progression. Learning to ride is the objective. While learning to ride may be the objective, in the process of learning to ride comes the therapeutic value. The long term goals may be physical, psychological, educational, cognitive, skill and/or recreational based. Therapeutic Riding Instructors are the primary professionals responsible for the design and implementation of the therapeutic riding session. The lessons can be taught privately, semi-privately or in groups of 3-6 students. The instructors will enlist the help of volunteers to aid the riders during lessons. These assistants may be horse leaders, side walkers or communicators. Depending on the goals of the individual riding students, the instructor may also involve educators or medical professionals to give input to the lesson plan.
