As a private swim instructor, your duties are to schedule lessons with individual clients, assess their swimming capabilities, and develop training regimens or goals for your client. Your responsibilities depend on the type of instruction you do. If you teach children who have no experience with swimming, your main goal is to provide students with introductory lessons about how to swim and ensure their safety in the water. Private swim instructors for a high school or college athletes develop training strategies and improve their athlete’s skills for competition. Adult private swim instructors have similar responsibilities.
