Much of MAC's success, and the success of its ensembles, can be traced to its classification system which is based on age (locally) and also tied to national standards. Please read below to have a better understanding of where your ensemble will fit, and why. National classes (SNA, INA, SO, IO, SW, and IW) must compete in the same class locally that they will compete in nationally.
