Class History
From 1930 to 1972, there were two classes of basketball, Class A
(Heavyweight) and Class B (Lightweight). An additional class was added in 1973--Class C (7th Grade). The Heavyweight and Lightweight classes were based on age, height and weight. From 1977-1984, the Heavyweight class was divided into two classes based upon enrollment--(A & AA). From 1985-2006, the Association adopted the format of 7th and 8th grade play based upon a school's enrollment (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.
