The Proper Way to Wear a Mortarboard

"[T]he mortarboard should be horizontal (parallel) to the floor. Imagine it to be a flat surface on which a cup or book can be placed. If the mortarboard is tilted upward, it is worn incorrectly. Some graduates position the mortarboard poorly to accommodate hairstyles. However, it should be flat and secure on top of the head."
