The primary competitive season for most NWAPA members is the fall marching band season. More than 5,000 students and 20,000 spectators will attend NWAPA events from September to November each year. The most popular events are those whose history predate the founding of the circuit, including: Pacific Coast Invitational sponsored by
Sprague High School, Sunset Classic sponsored by
Sunset High School, and the University of Oregon Festival of Bands. The competitive season ends with the NWAPA Championships hosted the last Saturday of October or first Saturday of November by one of the circuit members, or by either
University of Oregon or
Oregon State University. The first circuit marching band championship was hosted in 2000.
Event model Events or "shows" are scheduled via a bidding process which begins several months before the competitive season. Considerations for awarding an event include available volunteer personnel and experience, past show sponsor history, and available facilities. As of 2017, show sponsors must pay NWAPA an administrative fee, and all participating band attendance fees are also retained. As a result of this change, adjudicator travel, lodging, and other administrative functions are coordinated by NWAPA and not the show sponsor. This alleviated a number of on-going issues for sponsors, such as travel and lodging arrangements for visiting adjudicators. The modified system required fewer adjudicators. However, NWAPA's handbook was changed the following year to increase the number of adjudicators to the previous number.
Captions and rubric Scoring is based on three broad categories: Effect, Music and Visual. The categories are further divided into six reference criteria, or captions, with each given a maximum value of 200 points, or up to 20 points when factored. One adjudicator is assigned to each caption, including one adjudicator for Percussion and Auxiliary. An additional adjudicator is responsible for Timing & Penalties. The final score is tabulated by adding all captions, once factored, less any penalties. NWAPA does not have captions for
drum majors,
twirling teams and majorettes, or
dance teams. Performance excellence by a drum major is recognized by the Music or Visual adjudicators where appropriate. Twirlers and dance teams would fall under the responsibility of the Auxiliary adjudicator. Almost all participating bands will perform with a
color guard team.
Placements and awards Beginning in Fall 2017, scores are no longer announced at shows. Podium placings (1st, 2nd and 3rd) are announced for each class following prelims, as well as awards for High Brass, High Visual, High General Effect, High Auxiliary, and High Percussion. For finals, only top five placing bands are announced, along with caption awards. At NWAPA Championships, an overall champion is also announced. Caption recaps and scores are made public following the show.
Event flow Most events consist of two rounds: preliminary and final. In the preliminary round, bands compete based on class. The highest placing bands advance to the final round.
Preliminary round As of 2019, the performance order of performance for each class was set as A, AA, and AAA for all future events. Units within each class perform in order drawn at the beginning of the season. Each show sponsor sets a maximum number of bands who will advance to the final round; typically between twelve and fifteen bands. The highest scoring band in each class automatically advances to the second round, as well as the next-highest scoring bands, regardless of class, up to the maximum number allowed.
Final round Finalists are ordered into groups of four, five or six based on their preliminary score called
neighborhoods. The performance time for each band is the result of a random draw within each neighborhood. The size of each neighborhood is based on the number of competing bands who are advancing to the final round. All finalist bands compete in Open class.
