The University of Pennsylvania will not be making any changes to its early admissions policy in the near future. That according to Dean of Admissions, Lee Stetson, who said Penn's decision to admit nearly half of each year's freshman class early plays a large role in creating a positive campus culture (meaning Penn is filled with students happy to be at Penn).
From The Daily Pennsylvanian article: "He estimated that Penn was the first-choice college for 75 percent of students here, which makes a demonstrable difference in their dedication and involvement."
