The University of Iowa's 2013 Council Publication lists the required GPA for each chapter. Assuming what's listed is accurate, I think it's great to be so upfront.
I'd add a link to it, but am not sure how to do that from my iPad. Sorry!
Panhellenics need to put warnings in their recruitment information. If they don't, women with low GPAs will think they were only allowed to rush so PH could collect the fees.
I remember a girl who rushed in 2005 at a Georgia school. She had a 2.5 and I was astounded that PH let her rush but her mom said none of the literature said a thing about grades. The PNM was cut from every group after first rounds. Greek mom was sad and her daughter was mad about the wasted fee.
