Is that actually a program? I thought that was just a supplemental (and optional) form one could fill out as part of their application package. If that's the supplemental form you're talking about, does filling that out mean that you hear earlier?? Or maybe you just mean hearing re: interviews.
WildZooVet, hoodle (who hasn't been posting on the boards for a while, but may still be around somewhere) is in the VSTP program. I remember her saying that they interviewed earlier than everyone else. In early to mid Feb, maybe? You might want to PM her, I'm sure she could answer some of your questions.
Good luck!
