I'm not up-to-date with the recent changes to PACE - I was speaking to my experience as an advisor some years ago.
I will try and do some research, however.
Tri Sigma sent some information for us to use for our Alumnae Panhellenic Inforamtional Tea, and I too was really impressed with the program.

I think sometimes we're afraid that there are so many other things available for college students now, that they'll run in the other direction if they know how hard it can be. That IMO underestimates college students, and underestimates our orgs' value too.
