The Tournament of Bands sanctions about 140 marching band competitions throughout each fall, corresponding roughly with
high school football season. Bands are judged on a 100-point linear scale by judges both on the field and in the press box. Bands are also divided into groups based on their size, and judged only within their group. Sizes are as follows: In addition to the group sizes, there are three levels of performance classification that a member may elect to participate:
Open Class (formerly
Championship) – Highest level of competition, intended for experienced bands.
A Class (formerly
Regional and
Invitational) – Intended for young bands prepared to compete at the regional or state-level.
Festival Class – Intended for young and developing bands. No scores are given for this class, only ratings. Every class and group combination is available at all TOB-sanctioned events and Chapter Championships, or regional championships. Festival Class is not available at the annual Atlantic Coast Championships, only Open and A Class. == Indoor activities ==
