 Class HistoryThe IESA sanctioned girls basketball in 1979. There was one class of girls basketball until 1986 when the activity was split into 7th and 8th grade classes. From 1990-2005, the Association adopted the format of 7th and 8th grade play based upon a school's enrollment (7A, 7AA, 8A and 8AA). Starting in 2006, 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 |
