The Paul H. O'Neill School of Public and Environmental Affairs is the public policy and environmental studies school of Indiana University with locations on both the Bloomington and Indianapolis campuses. It is the largest and highest-ranked public policy and environmental studies school of its kind in the United States. Founded in 1972, as the Indiana University School of Public and Environmental Affairs, it was the first school to combine public management, policy, and administration with the environmental sciences. O'Neill School Bloomington is the top ranked school of public affairs in the United States. The school received a facelift and expansion when the Paul O'Neill Graduate Center opened for classes in the Spring 2017 semester due to the growing influx of students. In 2019, the name was changed to the O'Neill School of Public and Environmental Affairs in honor of alumnus Paul H. O'Neill who served as the United States Secretary of the Treasury in 2001–2002.
