NEW UPDATE: 20/21 LESSONS Stroke Refinement and Proficiency: Swimmers belong here if they can tread and float for more than 1 minute, perform an open and/or flip turn at the wall, swim 100 yards of freestyle and backstroke, swim 50 yards of butterfly and backstroke, and can perform underwater streamlines for 3 body lengths. If the swim lesson level you would like to register your child for is full, please add them to the waitlist, as we tend to create new classes in a session depending on waitlist numbers and class demand. Your account is not charged until you are moved from the waitlist to actual enrollment.
