Who guarantees placement?

[psy]

Does anyone know when Tufts changed from guaranteed placement (i.e., everyone gets a bid, even if they get cut from all three houses or fail to maximize their options) to guaranteed bidding (i.e., if you go through pref and maximize your options throughout recruitment, you are guaranteed a bid)?

Their 2008 viewbook (the latest currently posted on their website) says,
"Please understand that this is a mutual selection process. After each round, you will preference a certain number of chapters and each sorority will preference a certain number of women. Participation in Recruitment does not obligate you to join a sorority nor does it guarantee memberships"

Based on this, it seems Tufts now has guaranteed *bidding*, similar to that done by UT and some other universities, but I remember reading about the sorority system there having guaranteed *placement* when I was looking at colleges in 2005-2006.

I'm just curious as to when they made this switch.

Thanks!
