 1200 +/- students attend Shelby County High School, grades 812.Shelby County is unusual among U.S. high schools because it, like neighboring Martha Layne Collins High School, houses grades 812, while most schools house grades 912.However, the 8th Grade students at the two high schools are merely housed there, and are enrolled as students at their respective middle schools, in addition to participating in after-school activities there (Shelby West for Collins, Shelby East for SCHS).
