Swimmers within the team may be at varied levels of competence and require different types of coaching. Using patience and tact is necessary for swim coaches, or they may find themselves face to face with angry parents. Leading swim team members by motivation and inspiration should be a main goal of swimming coaches. Coaches work on personal and team development. They plan practices, drills or swimming exercises and other team events. High school swim coaches select members through a series of tryouts by students hoping to make the team. College coaches choose talented recruits from senior high school swim teams.
