University of Utah apparently requires 3 academic and three supervisor letters. What does this mean supervisor letters? I can get letters from the vice-president of my school, my scholarship supervisor, and the sponsor of a club I am in. Is this what they mean? Only one of them have their doctorate. I have been all over their website and can't find an answer. Also, I would like to use a letter from the head TA of my service learning internship. Although it was a class I took for credit, it really had an impact on me and I think she would write an awesome letter. Could this be a community letter?
