“The Collegian”::“PERSONAL STATEMENT
Please write a brief statement (1 paragraph to 1 page) describing why you wish to live at The Collegian. You may include descriptions of your
commitment to academic success, experiences that have taught you to be a good neighbor, and particulars about your lifestyle that are consistent with
The Collegian’s Code of Conduct.”
