 Class HistoryFrom 1976 to 1984 there was one class of Girls Volleyball, which was split equally into Class A and Class AA by school size in 1985. From 1989 through 2006, Classes A and AA were further divided into 7th and 8th grade levels (7A, 7AA, 8A and 8AA). Starting in 2007, the Association adopted a four class system in each grade level (7-1A, 7-2A, 7-3A, 7-4A, 8-1A, 8-2A, 8-3A and 8-4A).  The current classification system assigns 25% of the schools to each of the four classes. How Class Split is Determined |
