Want to pick up some hours for a short-term commitment? Seek WSI to teach all levels of swim classes to children. Maximum eight kids per class, often fewer than four because classes are drop-in. Classes run June 25-August 2, on Mondays, Tuesdays, and Thursdays. There are two sets of half-hour classes per day - 9:30-11:30 and 3:30-5:30. Can teach mornings, afternoons, or both.
