Bands are split into four classes—A, B, C, and D—determined by the size of the schoolthe band represents, though bands are permitted to participate in the class immediately larger than the one they would otherwise be assigned to if they wish. Prior to 1983, bands were assigned to one of seven District sites around the state. Bands receiving a Division I rating at their District advanced to State Preliminaries for their class, and the top five bands from each class preliminary performed in that class's State Finals the same evening. Beginning in 1983, State Preliminaries was removed, and instead bands receiving a Division I rating at District competition advanced to, depending on their geographic location, either the North Regional or South Regional for their class, two weeks after District. The top five bands from each regional in each class then advanced to State Finals the following week, resulting in ten bands per class at Finals. Numerical division ratings were replaced with Gold/Silver/Bronze/Participation ratings in 2004, but otherwise the format remained essentially unchanged through 2007. Beginning in 2008, the top ten bands from each class at each Regional site will advance to a new Semi-State round of competition, held the week immediately following Regionals. Of the twenty bands in each class at Semi-State, the top ten will then advance to State Finals the following week.
Scheduling
From 1983 through 2007, State Finals was typically scheduled for either the seventh or eighth Saturday after Labor Day, with Regionals being the Saturday prior and District two or three Saturdays before Regionals. An open weekend was allotted between District and Regionals should a change of date for District be necessitated by inclement weather ; however, no such weekend was allotted between Regionals and State Finals due to the difficulty of securing venues for the final two stages of competition. The weekends prior to District, generally beginning with the first Saturday after Labor Day, were used for various unsanctioned invitational competitions organized by high schools and, occasionally, colleges or other independent organizations. Beginning in 2008, State Finals was pushed back to the first Saturday in November, on the ninth Saturday after Labor Day. The move was necessitated by the decision of the administrators of the Indiana Convention Center to schedule the Future Farmers of AmericaNational Convention on the weekend that had historically been used for State Finals. To create a truer top ten bands from around the state, ISSMA created the semi-state round. Previously, it was merely the top five from each of the regions. The schedule up to and including Regionals weekend remains the same.
