What is the swimming ratio for 4-year-old children?

• A. 4:1
• B. 1:1
• C. 2:1
• D. 3:1

Answer: (A)

Young children in water need close, continuous supervision. For four-year-olds, the standard supervision arrangement is one instructor for up to four children. This four-to-one ratio lets the instructor keep everyone within reach, monitor each child’s comfort and safety, and respond quickly if someone needs help, while keeping the class size manageable. Ratios that are tighter (like one-to-one, two-to-one, or three-to-one) require more staff per child and aren’t the baseline for typical preschool swimming classes, though they might be used in special cases. So the best choice reflects safe supervision balanced with practical staffing, which is four children for every instructor.
