What should I ask about a swim school’s instructor-to-student ratios in practice?

Begin with the school’s own policy. What ratio does it advertise for each level, and who sets it? Then ask for class lists and instructor schedules for a few typical weeks. Check whether the numbers in the pool match the policy, especially in the busiest time slots.

Next, sit on the deck. Watch whether instructors can see and reach each child, how they handle a nervous beginner, and whether helpers or lifeguards are present. Ratios that look fine on paper may not hold when a child needs one-on-one attention.

Finally, ask how absences are covered. Does the school keep spare instructors, merge classes or cancel? Ask about complaints from parents and what was changed. Your insurer and lawyer can tell you how ratios affect coverage and obligations. A school that keeps its ratios honest, even when it costs revenue, is usually one that families trust. Ask too about how instructors are trained and supervised, and whether newer instructors work beside experienced ones. A good ratio is less useful if the person leading the class is unsure of the level.

Key takeaways

• Compare the advertised ratio with class lists and what you see in the water.
• Ask how absences and oversubscribed classes are handled.
• Have your insurer and lawyer confirm what ratios affect.
• Ask how new instructors are trained and supervised.
