An installation of 857 empty school desks, representing the number of students nationwide who are dropping out every hour of every school day, is on display at the National Mall June 20, 2012 in Washington, DC. The installation was presented by the College Board to call upon presidential candidates who are running for the White House to make education a more prominent issue in the 2012 campaigns and put the nation's schools back on track.
