Wise Swim school offers swim lessons with very low ratios (4 to 1). The lessons use a variety of teaching tools that assist students in the development of their skills. The teachers all do a wonderful job and the program is clearly laid out. When you look at the prices, they seem high and they are higher than other lessons. However the ratios are much lower. Other lessons I have seen are either 1 to 6 or 1 to 8 ratios. I have also seen other programs where the teachers appeared to not be trained as well.
