Because of the large number of teams in the conference, the conference has historically been divided geographically into sub-conferences and divisions. Prior to the 2014–15 school year, there were four conferences: Suburban East, Suburban North, Suburban South and Suburban West.[1]
In 2018, the St. Louis Suburban Public High School Athletic and Activities Association re-aligned their conferences into various pools by sport. This decision essentially made the existing sub-conferences and divisions irrelevant, as a given school competes against a different pool of schools in each sport. For purposes of athletic competition, pool assignments are based on the following factors: athletics offered, competitive balance, competitive trends, diversity, and school size. The number of pools varies from two (boys volleyball) to five (football), depending on the sport, with most sports having three or four pools.[2] Pools may be realigned if one or more of the previously mentioned standards are not met.
The Suburban Conference has some historic rivalries between its schools, but also those that are generally unknown outside the community.
(Note: most of the following information mainly applies to football. The intensity of these rivalries, and their rivalries in general, can vary by sport.)
The most notable and historic rivalry between any Suburban Conference member school is, by far, the rivalry between the Kirkwood Pioneers and the Webster Groves Statesmen football teams. Their "Turkey Day Game" on Thanksgiving has been a St. Louis tradition for well over a century, with the winner of the game being awarded the "Frisco Bell" trophy. It is the only remaining traditional Thanksgiving Day football game between two Missouri high schools, and is the only one in the state to be held after the MSHSAA State Championship game. This game's traditional date also means that they are the only two schools in the state to have an extra bye week during the regular season.
A generally unknown rivalry is the battle between the Mehlville Panthers and the Oakville Tigers. There is a noticeable "big brother, little brother" hatred between the two Mehlville School District high schools, Mehlville High being the older, more established institution compared to its counterpart. Students usually know someone attending the other school, influenced both by the schools’ close proximity to one another and the district's feeder system.[3]
