We have requirements. Most pledges complete them just fine. There are some who fall short and then their big just cries on the stand for them and get it waived
But if the cause of low retention wasn't can the person do the work, then what was it? That's where I was coming from when I said find out more about them before they get in. Do they plan to do this for a while or are they just willing to be here and do this for this semester, since it isn't that complicated, or are they really here for the long haul?
