The Atlanta Journal Constitution won a 2012 Hillman Prize for exposing a massive teacher cheating ring in Atlanta’s schools. The scam has been called the largest academic fraud in U.S. history. 

Closing arguments began Monday in the trial of 12 teachers accused of changing answers on standardized test papers to give their students higher scores. Twenty-one of the original 35 defendents struck plea bargains, and 2 others have died.
