For everyone's FYI, most of these plans are mandated from the top down, not necessarily dreamed up by the Greek Advisor, for whom in most cases this creates a lot of additional work (as well as for the students). This is a paradigm in higher ed that a lot of schools are adopting because presidents and vice-presidents are calling for it. Take a look at "A Call for Values Congruence" put together by a group of college/university presidents and excutive directors for some NIC/NPC groups. While not directly a "Delaware Plan", the "Sample Greek Community Standards" (page 6) certainly parallels it. Here's the link :
