The football team of Westfield High are the "Westfield Wolverines".
The "Westfield Wolverines" are the actual high school football team of Westfield Academy in Westfield, NY.
The "shooting victims" are actual people who work on "American Horror Story" and is an in-joke among crew members: Jay Cannavo is the AHS production assistant, Luke Maxcy is the Director's Guild of America Trainee working on AHS, Josh Sathre is production secretary for AHS, Mark Finstein is a set decorator, etc...
Only one cast member playing a high school student is actually high school age: Taissa Farmiga, age 17. Bianca Lawson is 32, Evan and Allessandra are both 24, and Brad is 25.
The Westfield library is a partial reconstruction of the Columbine library. 
The design of the "Westfield Wolverines" mascot is from Dave Turton, Designer's Website . The font of the school's logo is possibly based on the logo of Westfield, Virginia, as well.
