One caveat: as mentioned above by nichols51 (quoting Jon Boeckenstedt), these draw rates are inflated for those schools that have a sizable number of Early Action/Early Decision admits.
If those are eliminated from the numerator (Yield Rate), then the actual draw will be maybe about 60-70% of what I posted above, in other words ranging from ca.
1-2 for the 2nd tier private uni’s (WUStL, Emory, Gtown, Johns H., CMU, USC etc) to
3-4 for the 2nd-echelon Ivies + Vanderbilt, Rice and Northwestern to
5+ for CalTech, Columbia, Chicago, Duke + HYPSM.
The general observation still holds that a highly selective private college or university should probably have a draw rate comfortably north of 1.0 to stand out as an elite private institution.
