Regarding Economic Diversity raised by @brantly above – a valid point. However, the University has announced a focused effort to increase the number of Pell Grant recipients over the next five years. There have been a few articles on progress to date and the targets – unfortunately none from 2016. Here is a sample – http://www.huffingtonpost.com/2015/06/29/washington-university-diversity_n_7690054.html
It will be interesting to see how diverse this next incoming class is – but given the University’s ongoing fundraising priorities that earmark resources to address the needs of those needing financial assistance, I would expect the positive trend to continue. Wash U definitely has a ways to go.
