Closure Policy: AIM Gymnastics runs 52 weeks per year, but uses a 4-class per month billing system (48 classes per year). This allows us to close up to four times per year for March Break, events, and other closures outside of stat holidays. There are at least four months per year in which families will receive five classes, with no charge for the extra class. In addition to providing unlimited makeup classes for personal absences, we provide two makeup classes each time we are closed.
