A free preview lesson is exactly what it sounds like – a free, no-obligation chance to bring your child to a Foss Swim School for a private session. It’s a chance for you to see Foss Swim School in action, see if you like it, and see how your child responds. It’s also the best way to get a precise level recommendation, since the instructor can see what your child already knows about swimming and how they perform.
