DePaul University in Chicago has announced that they are going test optional with the class entering in 2012.
DePaul is believed to be the largest university to date that has gone test optional. While this is a 4 year pilot program there is no reason to expect that it will not be permanent. Many other colleges have implemented test optional status on a provisional basis and to the best of my knowledge, none have reversed their decision.
I congratulate DePaul on taking this step to eliminate the testing requirement in admissions.
