Classes are initially registered by age. However, if SDS feels a student needs to be transferred into another class due to technique level it reserves the right to do so. Classes are subject to change due to demand and interest. A minimum number of students must be registered in order to run the class. A decision will be made, no later than one week prior to the first day of a class. You will be notified if the class is cancelled and your tuition/registration fee will be refunded.
