What if I don't Want to attend my high school graduation ceremony?

What Will they do? Can they legally NOT GIVE ME my diploma... If, for a hypothetical example, my old public school sent me to an alternative school [and I Was very Well, through technicality, a public school student] could they just say I "have to partake in [their] ceremony" or else I can just take the alternative school's diploma... but, let's face it, Where are you going to get in life With and "alternative" diploma... It's sorta like an "alternative" drivers license, doesn't go over very Well, noW does it?
