The Bands of America adjudication system is a criteria reference system, in which a band showing proficiency in particular criteria, or meeting certain criteria at a certain level, falls within a scoring range. It is the position of Bands of America that music is the more important aspect of the performance, with marching as the presentation and visual enhancement of the program. Similarly, more emphasis has been placed on the effectiveness of the general effect judges than on fine-line perfection of the performance judges. The weight of the numbers places 60% of the value on music and 40% on visual, as well as 60% on general effect and 40% on performance. Each judge is assigned a specific area on which he or she focuses, ensemble and general effect judges are located at a vantage point from above (i.e. press box), individual performance judges are located on the field.
