Swim Instructors work at public pools, private pools, gyms, swimming schools and other facilities that offer swimming lessons. They work with all ages, from infants to adults, teaching swimming lessons in one-on-one and small-group settings. For beginning students, they focus on water safety and becoming comfortable in the water. Instructors work with advanced students on refining their strokes to improve their form. The job duties go beyond just teaching swimming techniques. The Swim Instructor must maintain a safe and engaging environment while providing constant supervision. Customer service is an important aspect of the job, especially when working with younger students and their parents. Swim instructors evaluate the students to ensure they learn the skills. They also document attendance, injuries, incidents and complaints.
