There are three sections available: small jazz ensemble, large jazz ensemble and community ensemble. In school ensembles, ensembles must comply with the following conditions:
1. Members of the ensemble must be enrolled as full time school students at the school or group of schools that they are representing.
2. Staff members or outside players may fill a vacancy in the band when there are insufficient students to make up a full ensemble.
However, there must be no more than two outside players per band and these individuals must be identified before the adjudicated performance, should not fill a principal chair in the ensemble and must not feature as a soloist. Exception to this rule must be requested in writing.
