East vs. West Traditionally for state championship competition for team sports, Pennsylvania is divided into Eastern and Western regions. Districts 1, 2, 3, 4, 11, and 12 usually make up the Eastern Region; Districts 5, 6, 7, 8, 9, 10 usually constitute the Western Region. The winners of each region compete against each other for the state championship. However, since the creation of District 12 with the admission of the Philadelphia Public Schools into the PIAA, the East vs. West format has been abandoned for some sports in certain classifications, particularly at the Class AAAA level where there are more large schools in the East. For example, in PIAA football, District 3 schools compete in the early rounds of the state playoffs against Philadelphia schools in some classes, and against Pittsburgh schools in others. == Sports ==
