I don't know to be honest with you. I guess it depends on the show you want to see and the person working at the box office. I have done some student rushes in the past where they didn't even ask to see my ID. I have done others that were college IDs only (which didn't bother me considering that I am in college) and others that where you could have used any kind of student ID.
My only question for you is this. Do you have a regular photo ID? I am only asking because if you're trying to use your transcript you might need a photo ID to prove that the name on the transcript is your name. But, other then that, I don't know to be honest with you.
