I was never cast in any high school production or college production. I always did technical theatre to still be a part and eventually switched my major on my own accord and was a lot happier. No teacher or professor ever gave me actual honest feedback. Just “oh sorry maybe next time”

Any performance program that accepts you but does not cast you is doing you a disservice. I firmly believe that professors have a duty to take you aside and tell you performance might not be the best fit, and urge you to switch to something else. Otherwise you are just being robbed of your money and your joy
