PIMBA events provide both healthy competition and constructive feedback for performing bands. Directors pay membership dues in order for their ensemble to be classified as a member of the circuit. Classifications are broken down by the number of performing students in an ensemble. The current classifications are as follows: • Class A: 1–54 members • Class AA: 55– 74 members • Class AAA: 75–99 members • Class AAAA: 100+ members Directors may also choose to have their ensemble perform in judged exhibition or Festival Class. These bands will not be placed but will still receive judges' commentary and an individual score. From 1997 to 2012, PIMBA also featured a National Class– qualifications for this class included placing in the top five at BOA Regional competitions for two consecutive years or by special request of the director. The final competition to take place for each season is the PIMBA Championships. At the championships, bands receive final scoring in their respective classes with the top scoring band from each class being crowned a PIMBA Class Champion. The championships has historically been held at the following locations: 's Mighty Falcon Marching Band performing at a competition in 2022. •
