Why are lessons only 20 minutes long when there is one swimmer in a class?
In a 30-minute lesson with multiple swimmers, each swimmer gets a break while another swimmer takes a turn. With only one swimmer, it becomes a focused, private lesson. We find that 20 minutes of instruction is all that most children can absorb in one lesson. The bottom line is that a 20-minute private lesson provides similar instruction as a 30 minute semi-private group lesson.
