Dean's List is pretty much like honor roll but on the college level. My sister got on it the first semester at Bucknell University, and they'll send a letter home letting you know. Sometimes the local newspaper might feature your name also.
At Pitt they recognized Dean's List the first time I made it, with a certificate. I didn't get a certificate other times I made the list. Requirements to make it is a 3.50 semester QPA along with no grades below C and no W, I, etc. grades.
