Class History
The 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.
